Overview
You have just received Mirra Advanced OF Charts, or you are evaluating it. This tutorial takes you from an empty NinjaTrader chart to reading order flow confidently, in the order you will actually need things.
Work through Parts 1 to 4 on your first day — that is about 20 minutes and you will be trading with it. Parts 5 to 9 explain every feature in depth; read them as you go.
Close NinjaTrader completely — the whole platform, not just the chart. Installing while it is running is the most common cause of setup problems.
Run the installer and follow the prompts. It places everything where NinjaTrader expects it.
Start NinjaTrader. The first launch prepares the product automatically and may take a few extra seconds.
Activate your licence. Open Help → About, copy your Machine ID, and email it to [email protected] from your registered address. If settings open but nothing draws, activation is the first thing to check.
Your First Chart
Open a chart. Pick a liquid instrument you know well — NIFTY futures, BANKNIFTY, RELIANCE futures or a global future like ES. Set the timeframe to 5 minutes to start.
Add the indicator. Right-click → Indicators → Mirra Advanced OF Charts → Add → OK.
Set your market. Reopen the indicator settings and go to group 00. Exchange & Session:
Exchange preset → choose your exchange (NSE, MCX, CME…). This one dropdown calibrates imbalance volume, big-trade size, rows per bar and absorption range sensibly for your market.
Volume notation → INR Lakh/Crore for Indian markets (1.25L, 3.02Cr) or International K/M for global markets.
Lot mode → Auto for F&O so volumes read in lots; Off for cash equity and spot indices.
That is the entire required setup. The chart is now trading-ready.
Step 4 — Read the header. The dashboard's title line confirms your setup: ◆ MIRRA OF · NIFTY · Row 2.5 · Lot 75. Row = price per row; Lot appears only when lot mode is active. If numbers ever look smaller than you expect, check for that Lot tag — you are seeing lots, not units.

Reading it
Reading a Footprint
This is the core skill. Everything else supports it.
Each bar is a column of price rows. In the default BidXAsk mode, every row shows two numbers: sell volume on the left, buy volume on the right at that price. So 4,875 | 9,165 means 4,875 traded into the bid (sellers hitting) and 9,165 traded into the ask (buyers lifting) at that price.
Use case: you no longer ask "was that green candle strong?" — you see whether buyers actually paid up, and at which prices.
Above and below each bar: total volume on top, net delta underneath (green positive, red negative). Benefit: bar size and net aggression in one glance.
The coloured markers tell you what happened. The most valuable ones to learn first:
Yellow box — the bar's POC (highest-volume price). Use case: acts as a micro support/resistance on retests.
Purple band — the bar's value area, where ~70% of volume traded. Benefit:
separates real business from rejected extremes.
Green/red dots beside cells — imbalances, where one side overwhelmed the other diagonally. Use case: shows exactly which prices were fought over.
Shaded green/red zones — stacked imbalances forming support/resistance.
Benefit: these are among the highest-probability levels on the chart; they extend right until price closes through them.
Rings at the cluster edges — big trades: a green ring on the right for a large buy print, a red ring on the left for a large sell print. Use case: spot the moment a large participant steps in, and on which side.
▲ / ▼ triangles — delta divergence: price and flow disagreed. Benefit: the earliest warning that a move is running out of committed flow.
◆ diamond — delta flip: conviction changed sides with force. Use case: one of the best entry triggers when it happens at a zone or VWAP.
○ circle — absorption: heavy volume in a tiny range. Benefit: the absorbing side usually wins, so this often marks reversals.
Exercise: scroll back through yesterday's session. Find one shaded zone, then watch what price did when it returned to it. Do this three times and zones will stop being decoration and start being levels you trade.
Your First Trade Decision
Open the AI Guidance panel (top-left by default). It answers four questions in the order a trader actually asks them:
MARKET — what is happening? A headline verdict such as INITIATIVE BUYING CONFIRMED or FAILED AUCTION AT LOWS, with a confidence % and whether price is inside, above or below value. Beneath it: the key numbers (Δ, CumΔ, UT/DT, COT↑, COT↓), the session phase, and how long this verdict has held (since 14:00).
EVIDENCE — why? Five bullets: control split, flow narrative, auction type and aggression, inventory, and the nearest key level.
NEXT — what is most likely? Rotation-versus-trend odds plus the concrete trigger: "Hold above IB High 23975.00 → trend continuation; back inside → failed break."
RISK — what would invalidate this? A price: "below 23923.00 — bias voided; stand aside and reassess."
PLAN — the action line, coloured to the bias. When confidence is under 50%, it opens with "Low conviction — half size".
Use case: you are watching four charts and need to know which one deserves attention right now. Benefit: entry logic and exit logic in one card, with the numbers behind it visible so you can verify rather than trust blindly.
The Statistics Table
Below the chart sits a table with one column per bar. You choose which rows appear — 14 individual switches in group 06. Statistics.

Use case: most traders need three or four of these, not fourteen. Switch the rest off and the chart returns that space to price. Benefit: a table built around your method rather than someone else's.
Tip:Stats font size is separate from the footprint font, and row height auto-expands if the font would not fit — text can never be clipped.
You can also print COT ↑ / COT ↓ directly on the bars (group 04. Signals → Show COT on bars). Use case: watching continuation pressure without looking down at the table.
Levels That Matter
These are the reference prices professionals trade around. All are tagged with their price at the right edge.
VWAP — the institutional fair-value benchmark. Buyers control above it, sellers below. Use case: the single most watched intraday level; pullbacks to it are classic entries.
VWAP ±1σ / ±2σ bands — statistically stretched zones. Benefit: the ±2σ band plus a divergence marker is a high-quality mean-reversion setup.
Session VPOC (gold line) — the session's highest-volume price, computed at tick precision so it matches the Mirra Market Profile product exactly. Use case: a magnet — price repeatedly returns to it.
Developing VPOC (blue steps) — how fair value migrated through the day.
Benefit: one of the cleanest trend reads available; rising VPOC with rising price is a healthy uptrend.
Naked POCs (gold dashed rays) — prior sessions' VPOCs that price has not yet returned to. Use case: excellent profit targets and reaction levels. They can also raise an alert when touched.
Initial Balance (IB High / IB Low) — the opening period's range. Use case: a clean break signals a trend day; a failure back inside signals rotation. The AI panel's trigger and risk lines are built around these levels.
Session profile (right edge) — the volume histogram for the session. Benefit: high-volume nodes are support/resistance; low-volume gaps are where price travels fast.
Live price dot — a gold dot marking the current traded price. Use case: instantly locate where the market is trading among all these levels.

Feature guide
Every setting in Mirra Advanced OF Charts, in the order it appears in NinjaTrader's Properties panel. Each entry tells you what it does and why it matters, with its default and range. The defaults are trading-ready — you can use the indicator immediately and tune at your own pace.
Group 00 · Exchange & Session
The first four settings calibrate the indicator to your market. Set these once.
Exchange preset
Default: Custom
What it does
selects a calibration profile for your market, supplying sensible values wherever a threshold is left at 0 (Auto)
Why it matters
a "big trade" on NIFTY is nothing like one on the LSE; selecting your exchange means every signal is sensibly scaled from the first bar instead of after an hour of manual tuning
Options
Custom, NSE India, BSE India, MCX India, CME, CBOT, NYMEX, COMEX, Eurex, ICE, LSE, JPX Osaka, HKEX, SGX, ASX, B3 Brazil, Crypto
Volume notation
Default: INR Lakh/Crore
What it does
chooses how volumes are written on the chart — Indian Lakh/Crore (1.25L, 3.02Cr) or international K/M
Why it matters
numbers you read at a glance should be in the units you think in
Options
INR_Lakh_Crore, International_K_M
Lot mode
Default: Off
What it does
converts displayed volumes into lots. Off shows raw units; Manual uses the lot size you enter; Auto detects it live from the trade stream and self-corrects if the exchange revises it
Why it matters
an F&O trader seeing "66 lots" of aggressive buying can act immediately; "4,950" means nothing
Options
Off, Manual, Auto
Lot size (manual)
Default: 1
What it does
the contract's lot size, used when Lot mode is Manual
Why it matters
exact control for a specific contract (for example NIFTY 75, BANKNIFTY 35)
Options
1 to 100000
Group 01 · Display
How the footprint looks, and how each trade is classified.
Display mode
Default: BidXAsk
What it does
what each price row shows. BidXAsk puts sell volume and buy volume side by side (the classic footprint); Delta shows the net; UpTickXDownTick uses the Indian tick convention.
Why it matters
BidXAsk suits most futures; switch to UpTickXDownTick on spot indices and cash equity where tick direction is the true aggression read
Delta source
Default: Auto
What it does
the single most important setting — how each trade is classified as buying or selling. Auto uses bid/ask when the feed provides a genuine spread and the tick rule otherwise; BidAsk forces spread-based; UpDownTick forces tick-direction.
Why it matters
every number in the product flows from this. Auto is correct for almost everyone — it also health-checks the feed and locks to the tick rule on instruments with no real spread
Theme
Default: MirraDark
What it does
MirraDark or MirraLight colour scheme
Why it matters
matching your chart background keeps every number readable
Auto-fit view on load
Default: on
What it does
widens bar spacing once when the indicator loads so footprints are legible immediately
Why it matters
you never have to stretch a chart manually to read numbers. It only widens, only once — your own zooming afterwards is always respected
Show central candle
Default: on
What it does
draws a slim candle down the middle of each footprint
Why it matters
keeps familiar price structure visible while you read the cluster; turn off to pack bid and ask columns closer
Auto-fit bar spacing
Default: 42
What it does
the target spacing in pixels used by auto-fit
Why it matters
raise for more room between bars on a large monitor; lower to fit more bars on screen
Options
20 to 80
Show volume/delta totals
Default: on
What it does
prints total volume above and signed delta below each bar
Why it matters
the fastest read of a bar's size and net aggression without consulting the table
Show info dashboard
Default: on
What it does
the glass summary card with session delta, volume, and the BUY/SELL and UT/DT gauges
Why it matters
a three-second read of whether the session is one-sided or balanced before analysing any single bar
Auto row size
Default: on
What it does
automatically chooses how much price each row covers, based on instrument and timeframe
Why it matters
NIFTY, BANKNIFTY, crude and equities all become readable with zero setup, and it adapts when you change timeframe
Target rows per bar (auto)
Default: 0 (Auto)
What it does
how many rows auto-sizing aims for per bar; 0 uses your Exchange preset's value
Why it matters
raise for finer price resolution when scalping; lower for a cleaner, chunkier footprint on higher timeframes
Options
0 to 60
Row tick adjust (auto +/- ticks)
Default: 0
What it does
fine-tunes the automatic row size by adding or removing ticks per row
Why it matters
you keep the convenience of auto-sizing while nudging granularity to taste — no need to switch to fully manual
Options
−1000 to 1000
Ticks per row (manual)
Default: 5
What it does
the fixed ticks-per-row used only when Auto row size is off
Why it matters
total control for traders who want an exact, unchanging row size on every chart
Options
1 to 1000
Font size
Default: 11
What it does
text size for the footprint numbers
Why it matters
raise on high-resolution monitors; lower to fit more data on screen
Options
6 to 24
Min cell volume filter
Default: 0 (show everything)
What it does
hides row volumes below this number
Why it matters
on very liquid instruments it strips out trivial prints so only meaningful volume stands out
Brand color (Accelpix / mirracharts.com)
Default: Blue
What it does
Blue or Yellow for the on-chart brand mark and the statistics label accent
Why it matters
pick whichever contrasts best with your theme
Show live price dot
Default: on
What it does
a gold dot at the current traded price on the right edge
Why it matters
among VWAP, VPOC, IB and band tags, this tells you instantly where the market actually is
Volume shows the row total; DeltaPercent shows the net as a percentage;
Group 02 · Imbalance
Finding where one side genuinely overwhelmed the other.
Imbalance ratio %
Default: 300
What it does
how lopsided a diagonal comparison must be to count as an imbalance (300 = one side is 3× the other)
Why it matters
your signal-to-noise dial. Raise to see only the most extreme fights; lower to catch subtler pressure
Options
100 to 10000
Min imbalance volume (0 = Auto)
What it does
the minimum volume a cell needs before it can be flagged; 0 uses your Exchange preset's value
Why it matters
prevents imbalances built on tiny prints. On index instruments with very large volumes, raising this substantially is the single best way to reduce marker clutter
Stacked count
Default: 3
What it does
how many imbalances must stack vertically to create a support/resistance zone
Why it matters
lower to 2 for more zones on quiet instruments; raise to 4 for only the strongest institutional walls
Options
2 to 10
Highlight imbalances
Default: on
What it does
colours imbalanced cells brightly
Why it matters
makes lopsided prints jump out of the cluster instantly; turn off if you prefer reading only the dots
Show imbalance dots
Default: on
What it does
draws a green or red dot beside each imbalanced cell
Why it matters
a clean directional marker that stays readable even when you zoom out
Show stacked S/R zones
Default: on
What it does
draws the shaded zones created by stacked imbalances, extending right until price closes through them
Why it matters
these are among the highest-probability levels on the chart — the core of the zone-retest trade
Keep broken zones visible
Default: off
What it does
keeps zones on the chart after price has closed through them
Why it matters
turn on when reviewing or back-testing to study how price reacted to old zones; leave off for a clean live chart
0 (Auto).
Group 03 · Bar Structure
The volume structure inside each individual bar.
Show bar POC boxes
Default: on
What it does
highlights each bar's Point of Control (its highest-volume price) with a yellow box
Why it matters
shows where each bar found fair value — a natural micro support/resistance and a magnet on retests
Show bar value area
Default: on
What it does
shades the price range holding roughly 70% of that bar's volume
Why it matters
instantly separates where the business happened from the thin extremes where price was rejected
Value area %
Default: 70
What it does
the percentage of volume that defines the value area
Why it matters
70 is the market-standard definition; change it only if your methodology uses a different convention
Options
30 to 95
Show unfinished auctions
Default: on
What it does
marks bar extremes that traded with volume on both sides, meaning the auction there was not completed
Why it matters
these levels are statistically likely to be revisited — excellent targets and reaction zones
Frame max bid/ask cells
Default: on
What it does
outlines the bar's single largest bid cell and largest ask cell
Why it matters
locates the heaviest volume in a bar at a glance, which is where absorption and defence usually occur
Group 04 · Signals
The classic order-flow events, detected and marked for you.
Show delta divergence
Default: on
What it does
marks bars where price and delta disagree (▲ bullish, ▼ bearish)
Why it matters
the earliest warning that a move is running out of committed flow — a cue to tighten stops or prepare to fade rather than chase
Show delta flip
Default: on
What it does
marks bars where delta conviction flips sign with force versus the prior bar (◆)
Why it matters
one of the highest-quality entry triggers when it happens at a zone, VWAP or naked POC — it is the moment control changes hands
Show absorption
Default: on
What it does
marks bars where large volume traded inside a very small range (○)
Why it matters
absorption means one side is soaking up everything the other throws at it; the absorbing side usually wins, making this a powerful reversal signal at extremes
Absorption volume factor
Default: 2.5
What it does
how many times the average volume a bar needs before it can count as absorption
Why it matters
raise to flag only extreme events; lower to catch more moderate absorption
Options
1.0 to 20.0
Absorption max range (ticks) (0 = Auto)
Default: 0 (Auto)
What it does
the maximum bar range still considered absorption; 0 uses your Exchange preset's value
Why it matters
the essence of absorption is huge volume, tiny range, so this keeps the definition honest for your instrument
Show big trades
Default: on
What it does
marks large prints with a ring — green on the right of the cluster for a large buy, red on the left for a large sell
Why it matters
reveals individual large participants stepping in, and on which side, which often marks the start or defence of a move
Big trade size (0 = Auto)
What it does
the size that counts as a big trade; 0 uses your Exchange preset's value. 0 (Auto).
Why it matters
calibrate per instrument — a good rule is 10–15× the average trade size, which you can compute from the statistics table as Volume ÷ Trades. Read in lots when Lot mode is on
Options
0 to 10,000,000
Big trade calculation
Default: IndividualPrint
What it does
how the threshold is tested IndividualPrint requires one single trade at a price level to reach it — the true "large participant" detector. CumulativeRow also qualifies a level whose total buy or sell volume reaches it — an accumulation detector.
Why it matters
switch to CumulativeRow when you care about where size accumulated rather than who printed one big order
Show COT on bars
Default: off
What it does
prints C↑ above and C↓ below each bar beside the totals
Why it matters
continuation pressure at the extremes without looking down at the table
Group 05 · Levels & Profile
The session-level reference lines professionals trade around.
Show session profile
Default: on
What it does
draws the right-edge volume histogram for the session, split by buy/sell
widen for detailed shape analysis; narrow to reclaim chart space for price
Options
5 to 40
Show session VPOC line (gold)
Default: on
What it does
draws the session's highest-volume price, computed at tick precision
Why it matters
the session's fair-value magnet — price repeatedly gravitates back to it, making it a prime target and decision level. Tick precision also means it matches the Mirra Market Profile product exactly
Show developing VPOC steps (blue)
Default: on
What it does
shows how the VPOC migrated through the session
Why it matters
watching fair value climb or fall in real time is one of the cleanest trend reads available
Show naked POC rays
Default: on
What it does
draws prior sessions' VPOCs that price has not yet returned to touch
Why it matters
"unfinished business" levels act as strong magnets — excellent profit targets and high-probability reaction points; they can also raise an alert when touched
Show session VWAP
Default: on
What it does
the volume-weighted average price line, with a price tag at the right edge
Why it matters
the institutional fair-value benchmark. Buyers control above it, sellers below — the single most watched intraday reference
Show VWAP ±1σ/±2σ bands
Default: on
What it does
standard-deviation envelopes around VWAP, each tagged with its price
Why it matters
the ±2σ band marks statistically stretched extremes — prime mean-reversion territory, especially when a divergence marker appears there
Group 06 · Statistics
The numeric table beneath the chart. Three controls plus fourteen row switches.
Show statistics table
Default: on
What it does
master switch for the table
Why it matters
the hard, objective numbers behind the visual footprint
Stats row height (px)
Default: 15
What it does
the height of each row
Why it matters
raise for readability, lower to fit more rows in less chart space. Row height automatically expands if your chosen font would not fit, so text can never be clipped
Options
10 to 30
Stats font size
Default: 10
What it does
text size inside the table, independent of the footprint font
Why it matters
keep large readable footprint numbers while running a compact table, or vice versa
Options
7 to 16
The fourteen row switches
What it does
each turns one row on or off
Why it matters
this is your table builder. Most traders need three or four rows, not fourteen; switch off the rest and the chart returns that space to price. All are on by default
Setting
What it shows
Row: Ask
buy-side volume for the bar
Row: Bid
sell-side volume for the bar
Row: Delta
net aggression (Ask − Bid), green/red tinted
Row: Max Δ
the highest the running delta reached inside the bar
Row: Min Δ
the lowest the running delta reached inside the bar
Row: COT ↑
delta accumulated since the bar's high was set; strongly negative means sellers pressed a rejected high (hidden downside pressure)
Row: COT ↓
delta accumulated since the bar's low was set; strongly positive means buyers attacked a rejected low (hidden upside strength)
Row: B% / A%
the bid/ask percentage split (41/59 = 59% buy-side)
Row: Cum Δ
session-cumulative delta; is pressure building or stalling?
Row: Volume
total traded volume for the bar
Row: UpT Vol
volume traded on upticks
Row: DnT Vol
volume traded on downticks
Row: UT/DT
the uptick/downtick ratio, the primary aggression read on Indian instruments
Row: Trades
number of individual trades; Volume ÷ Trades gives average trade size
Group 07 · AI Assist
Show AI Assist panel
Default: on
What it does
displays the AI Guidance card, which reads VWAP position, session delta, UT/DT pressure, bar conviction, COT continuation, active zones, divergence, flips, absorption and tape pace together, then presents: MARKET (headline verdict, confidence %, value position, key numbers, session phase and how long the verdict has held), EVIDENCE (five supporting bullets), NEXT (rotation-versus-trend odds and the concrete trigger), RISK (the invalidation price) and PLAN (the action line).
Why it matters
a fast second opinion that also teaches — the numbers behind the verdict are visible, so you verify rather than trust blindly. It is fully local and deterministic: the same data always produces the same reading
AI panel position
Default: TopLeft
What it does
places the panel in any of the four chart corners
Why it matters
move it wherever it does not cover your price action; each position is aware of the dashboard, statistics table and brand marks so nothing overlaps
Group 08 · Auction Levels
Show level price labels
Default: on
What it does
draws price tags at the right edge for VWAP, VPOC, the VWAP bands and the active Initial Balance
Why it matters
you always know the exact price of your key levels without hovering or measuring — essential when placing orders quickly
Show Initial Balance lines
Default: on
What it does
marks the high and low of the session's opening period
Why it matters
breaks and holds of the Initial Balance are core session-structure trades — a clean break often signals a trend day, a failure back inside signals rotation. The AI panel's trigger and risk lines are built around these levels
Initial Balance minutes
Default: 60
What it does
the length of the opening period
Why it matters
match your market's convention; 60 minutes is the global standard, though some Indian traders prefer 30
Highlight fast tape
Default: on
What it does
turns the volume total orange when the bar's trade pace reaches roughly 2× average
Why it matters
spots bursts of urgent activity that a static volume number would hide — often the signature of news or a large participant entering
Group 09 · View Range
View range
Default: All
What it does
plots All bars, Current Session Only, or a Custom Range between two timestamps.
Why it matters
isolate a single session or a specific window for focused study; the session profile rebuilds for exactly the range you select, with its own VPOC and value area
Range start / Range end
What it does
define the Custom Range window
Why it matters
review a specific event day, or run two chart instances side by side (yesterday versus today) for a true comparison of two sessions' order flow
Group 10 · Alerts
Nineteen settings: four global controls, then an on/off switch and a sound file for each of the seven events.
Enable alerts
Default: off
What it does
the master switch
Why it matters
lets you step away from the screen and be called back only when something you care about happens
Default alert sound
What it does
the sound file used by any event that does not have its own
Why it matters
pick something distinctive so you recognise a Mirra alert instantly among other platform sounds
Alert cooldown (sec, per event)
Default: 10
What it does
suppresses repeats of the same event type within this window
Why it matters
in a choppy market a single event type can fire repeatedly — the cooldown keeps alerts useful instead of overwhelming
Options
0 to 600 (0 disables)
Alerts active from (HH:mm) / Alerts active until (HH:mm)
What it does
restrict alerts to a time window The seven event pairs — each event has an on/off switch and its own sound file (leave the sound blank to use the default).
Why it matters
no alerts during pre-open noise or after you close your desk. Overnight windows (for example 18:00 to 02:00 on MCX) are handled correctly
All seven event switches are on by default, but nothing fires until Enable alerts is switched on.
Setting
What it shows
Alert: stacked zone + Zone sound (blank = default)
a new stacked S/R zone formed
Alert: divergence + Divergence sound
delta divergence detected
Alert: delta flip + Flip sound
conviction flipped sign with force
Alert: unfinished auction + Unfinished sound
a bar extreme printed an unfinished auction
Alert: big trade + Big trade sound
a print reached your big-trade threshold
Alert: naked POC touch + Naked POC sound
price touched a prior session's untested VPOC
Alert: AI strong bias + AI bias sound
the AI verdict became strongly directional
Group 11 · Institutional Data (L2+)
Advanced order-book features. Off by default — they require a Level 2 / depth-of-market subscription.
Data level
Default: Auto
What it does
Auto, Level 1, Level 2, or Tick-by-Tick
Why it matters
tells the indicator what your feed actually provides so it uses the richest data available without guessing
Enable institutional (L2) features
Default: off
What it does
the master switch for the depth features below
Why it matters
unlocks order-book analysis for subscribers with depth. If depth is not detected, a one-time notice appears and the footprints continue working perfectly
Show book-pressure gauge
What it does
adds a BOOK gauge summing resting bid versus ask size across the top levels
Why it matters
shows where passive liquidity is leaning, which often precedes where price can and cannot go
Show liquidity walls
What it does
draws the largest resting orders on each side as labelled level lines
Why it matters
hidden support and resistance that no price chart reveals — large players showing their hand
Wall min resting size
What it does
the minimum resting size that counts as a wall
Why it matters
tune per instrument so only genuine walls are drawn
Show iceberg zones
What it does
marks prices where resting size keeps refilling as it is hit
Why it matters
reveals a large hidden order being worked quietly — classic institutional accumulation or defence at a level
Iceberg refill count
What it does
how many refills are needed before a zone is flagged
Why it matters
raise to reduce false positives, lower to catch icebergs sooner
Book gauge depth levels
What it does
how many book levels the gauge sums
Why it matters
widen for a broader liquidity picture, narrow to focus on the top of book
Group 12 · Marker Colors
Twelve colour pickers and one size control. Every choice saves with your chart template, so your setup travels with you.
Marker size %
Default: 100
What it does
scales all signal markers together
Why it matters
on 4K monitors the default markers can look small; on a busy scalping chart you may want them subtler. One dial adjusts them all proportionally
Options
50 to 200
Why this group matters: traders are highly personal about chart colours, and colour-blind traders often need specific palettes. Each picker changes one marker only, so you can make the signals you trade loud and the rest quiet.

Group 10. Alerts. Seven events can alert independently: stacked zone, divergence, delta flip, unfinished auction, big trade, naked POC touch, and AI strong bias.
Each has its own on/off switch and its own sound file.Use case: give zones a bell and big trades a chime — you learn which signal fired without looking at the screen.
Two settings make alerts livable:
Alert cooldown (seconds) — suppresses repeats of the same event type.
Benefit: a choppy market cannot machine-gun your speakers.
Alerts active from / until — for example 09:15 to 15:30. Benefit: silence outside market hours. Overnight windows (18:00 to 02:00 for MCX) work correctly.
A practical starting setup: enable alerts 09:15–15:30, cooldown 30 seconds, and switch on only stacked zone, delta flip and naked POC touch — the three events most traders act on. Leave the rest visible on the chart but silent.
Your Daily Routine
Open your charts and confirm the exchange preset and lot mode in the header
Check the AI panel on each — the headline tells you which chart is in play
Mark the levels you will trade around: VWAP, VPOC, IB High/Low, any naked POC
Wait for a level test — watch the footprint at that level for absorption, a
delta flip, or a stacked zone holding
Take the trade with an invalidation price, using the RISK line as a starting
reference
Let alerts watch the rest while you focus on your one chart
The discipline that makes order flow work: do not trade in the middle of the range. Wait for price to reach a level where the footprint can tell you something.

Settings That Are Commonly Misread
"My volumes suddenly look small." Lot mode is on and you are reading lots. The dashboard header shows a · Lot 75 tag when this is active.
"Big trade rings appear too often." Raise Big trade size — and remember it is read in lots when Lot mode is on. Also check Big trade calculation: CumulativeRow qualifies more levels by design than IndividualPrint.
"A threshold shows 0." That is the Auto convention, not an empty setting — 0 means "use my Exchange preset's calibrated value". Type any number to override it permanently.
"Some cells show 0 on one side." On instruments without a genuine bid/ask spread — spot indices and cash equity — classification uses the tick rule, so each trade is either an uptick or a downtick, never both. For decision-grade delta on a stock, use the futures contract.

FAQ
Common questions
Why do some cells show 0 on one side?
On instruments without a genuine bid/ask spread — spot indices such as NIFTY_I, and cash equity — classification uses the tick rule, so each trade is either an uptick or a downtick, never both. Real data, not a gap. For decision-grade delta on a stock, use the futures contract, where a real spread exists.
Why are there blank gaps inside a cluster?
Those are prices where no volume traded — price gapped through them. Mirra does not draw empty rows so the real data stays readable. Coarser rows remove the gaps.
Why did my volumes suddenly get smaller?
Lot mode is on and you are reading lots. Check the dashboard header — if it shows · Lot 75, that is why. Set Lot mode to Off for raw units.
My big-trade rings appear too often.
Raise Big trade size (a good rule is 10–15× average trade size, which is Volume ÷ Trades from the statistics table), and remember it is read in lots when lot mode is on. Also check whether Big trade calculation is set to CumulativeRow, which qualifies more levels by design.
