mzBigTrade

The mzBigTrade indicator detects and visualizes significant trades in the order flow. It aggregates tick data into trades, applies configurable volume and order flow filters, and renders the results as markers on the price chart. The indicator includes iceberg order detection, DOM pressure/support analysis, aggression (sweep) detection, and smart/predatory trade identification.

Data required: Level 1 (tick data)

Presentation Modes

ModeDescription
DefaultTrade markers are attached to chart bars at the price level where the trade occurred
TapeTrade-by-trade visual tape scrolling across the chart. Trades that pass filters are rendered with configurable marker size; trades below filters appear as small dots

In Tape mode, the tape can be placed over the chart, on the right margin, or on both. Use Tape: position offset, px to shift the tape left or right.

Marker Types

MarkerDescription
LineHorizontal line at the trade price level. Line length is proportional to trade volume. Configurable thickness scaling
BubbleCircle marker. Size is proportional to trade volume. Shows volume text inside
BoxRectangle marker. Size is proportional to trade volume. Shows volume text inside
BarVertical bar spanning the full price range of the trade. Clearly shows the sweep range of aggressive trades

Marker Position

Controls where the marker is placed relative to the trade's price range:

PositionDescription
FirstFirst tick of the trade
LastLast tick of the trade
HiHighest price of the trade
LoLowest price of the trade
POCPoint of Control — price level with the most volume in the trade
StackedTrades organized vertically as a chain within each bar (see Stacked Tape below)
StackedByTimeTrades of each bar laid out as a single time-ordered column (see Stacked by Time below)

Note: Stacked and StackedByTime positions are available for Bubble and Box markers only.

Stacked Tape

When Marker position is set to Stacked, trades are organized vertically by bar like a chain, in the order they arrive from the order flow. New buy trades are added at the top, and new sell trades at the bottom of each chain.

Stacked tape is useful when working with non-reconstructed tape or when there are many small trades for the instrument. Recommended for use on tick-based timeframes (e.g., 20 Ticks).

Stacked by Time

When Marker position is set to StackedByTime, all trades of a bar are laid out as a single column ordered by trade time, earliest first. Buy and sell trades share the same column — unlike Stacked, where buys grow upward and sells grow downward from the trade price. This makes the sequence of the bar's order flow easy to read.

Stacked by time: from bar edge (default: true) anchors the column at the bar edge it grows from — the high for an up bar, the low for a down bar — instead of at the trade price.

Click to Stack

Instead of switching Marker position permanently, you can stack a single bar on demand. With Click: stack trades by time enabled (default), left-click a bar holding two or more trades to temporarily lay its trades out as a time-ordered column. Click any of its trades again to revert.

Click-to-stack is available in Default presentation mode, with Bubble, Box, or Bar markers, and with Marker position set to First, Last, Hi, Lo, or POC. The stacked state is temporary — it is not saved and resets when the chart or script reloads.

Filtering

Filter Type

TypeDescription
AutoAutomatic statistical filtering. The number of displayed trades is calculated as Days x Trades per day. The largest trades within that range are shown. Iceberg size, DOM pressure, and DOM support are also considered in the selection. This filter is calculated when historical data is loaded and does not change live
ManualFine-grained filtering with individual controls for trade volume, iceberg, DOM pressure, DOM support, and selection. Use Logic to combine filters

Note: In Auto mode, the actual number of trades on the chart may exceed the calculated number if the loaded data spans more days than the Days value.

Filter Logic

When using Manual filter type, the Logic setting controls how multiple enabled filters are combined:

LogicDescription
ANYA trade passes if any enabled filter condition is met
ALLA trade passes only if all enabled filter conditions are met

Trade Volume Filter

The primary filter for selecting trades by volume:

  • Trade: min volume — minimum trade size (default: 50)
  • Trade: max volume — maximum trade size; set to -1 for unlimited (default: -1)

Volume-is-Multiple-of

This filter identifies market participants trading with significant rounded sizes. When enabled, only trades whose volume is evenly divisible by the specified value are shown.

Example: With value set to 100, trades with volumes of 100, 200, 300, 400, etc. will be displayed.

Iceberg Detection

Iceberg orders are large hidden orders executed in smaller visible portions. The indicator detects iceberg activity using three algorithms.

AlgorithmData requiredDescription
HardLive or Market ReplayUses volumes on best bid/ask price levels to calculate the size of the hidden liquidity. Strict detection requiring strong evidence of iceberg behavior
SoftLive or Market ReplayAdds positive DOM pressure (if any) to the iceberg size calculated by the Hard algorithm. Relaxed detection that flags more potential iceberg activity
TapeAny, including historicalEstimates hidden refilling-iceberg volume from the trade's fill composition rather than from the order book

Hard and Soft read the order book, so they work on live or Market Replay data only — NinjaTrader 8 does not provide the Level 2 data needed to reconstruct the book on historical bars. The Tape algorithm has no such limitation.

When iceberg volume is detected, the trade marker is rendered with a special border (Iceberg color). The iceberg border is shown if the iceberg value is greater than or equal to the iceberg filter threshold, even if the Iceberg filter is disabled.

Tape Algorithm

The Tape algorithm looks at how a trade was filled. A refilling iceberg leaves a distinctive trace: a run of consecutive fills of identical size at the same price, as the hidden order is replenished after each hit. That run is called a clip.

Two thresholds define what counts as a clip:

  • Iceberg: tape min clip (default: 20) — the minimum identical-fill size to consider.
  • Iceberg: tape min refills (default: 3) — the minimum number of consecutive identical fills that qualify as a refilling iceberg.

For a confirmed clip of N fills of size C, the hidden volume is estimated as (N − 1) × C, plus the trailing partial fill when it does not exceed the clip size. The result is deduplicated against the order-book estimate at the trade's start price, so enabling Tape alongside Hard or Soft does not double-count the same liquidity.

Because it reads the stored fill composition of an already-reconstructed trade, the Tape algorithm works on cold historical data where the order book is unavailable. Reconstruct tape must be enabled — but unlike Hard and Soft, the Tape algorithm also works with Reconstruct tape: timestamps only enabled, which is what makes it the iceberg algorithm to use when backtesting.

Tape is an independent toggle, not a value of the Iceberg: algorithm setting — you can run it on its own or together with Hard/Soft. Its result is written into the same iceberg volume, so the iceberg filter threshold, Marker size relative to = Iceberg, the Iceberg Volume Profile, and the pop-up all use it unchanged. Changing a Tape parameter recalculates the chart on the fly, with no reload.

note

The Tape algorithm is not available in the free version.

DOM Pressure

DOM pressure measures how aggressively a price level at the best bid or ask is defended — repeatedly consumed by same-side market orders and replenished within a short window. It is derived from the Level 1 quote stream (the volumes resting at the best bid/ask). Rather than measuring the liquidity change at the moment a single trade executes, mzBigTrade now follows a price level across trades with a refill-signature engine.

A signature forms when a level is hit and refilled again and again. As long as the level keeps being replenished the signature stays open; it closes when refills stop (idle timeout) or price walks too far from the level. The net refilled volume becomes the trade's DOM pressure:

  • Positive DOM pressure — the level was, on balance, refilled faster than it was consumed. Liquidity is being absorbed and the level acts as resistance to the trend
  • Negative DOM pressure — the level was, on balance, pulled: more liquidity was withdrawn than replenished (requires DOM pressure: track pulling)

DOM pressure detection is feed-time based and available on live data and Market Replay only — it does not run on cold historical bars. It is not available in the free version.

Detection vs. Display Filters

The DOM pressure settings split into two groups:

  • Detection (refill window, idle timeout, min refills, min volume, track pulling, max deviation from level) shape which signatures are recognized. They take effect only on freshly processed data, so changing one on a running chart prompts a chart reload.
  • Display filters (min abs. volume, min traded sig volume, min hold duration, min/max intensity) decide which recognized signatures are shown. They apply on the fly with no reload. A trade shown only because of its DOM pressure disappears when it no longer passes; a trade that also passes the trade-volume filter keeps its marker but loses the triangle.

Visualization

When Show DOM pressure is enabled, DOM pressure is drawn as a triangle in the Buy/Sell marker-border color, with the value printed inside it (auto-scaled). Negative DOM pressure (liquidity pulling) uses the Liquidity pulling line outline style.

As a level keeps being defended, its signature re-anchors onto newer trades ("moves right"), so the marker rides forward to the trade where the defense finally broke instead of appearing on the first hit.

Enable Show DOM pressure span to draw a 1-tick band at the level price spanning the signature's extent — from its first refill to the anchor trade — together with a proportion bar comparing the volume traded by the signature's refills against all volume traded at the level. Hovering the band shows that trade's pop-up.

The pop-up reports the signature on its own line, for example:

DOM pressure: 250-Lot (12) @7510.5 3.4s 74/s traded 180/240/75%

This reads as a net +250 contracts refilled across 12 refills at price 7510.5, held for 3.4 seconds at 74 contracts/s, with 180 of the 240 contracts traded at the level (75%) coming from the signature. The lead value is signed — a negative number means the level was net pulled.

Note: The DOM pressure filter uses the absolute value for comparison. For example, a trade with DOM pressure of -100 will pass a filter with min = 90 because abs(-100) > 90.

DOM Support and Market-Limit Orders

DOM support describes liquidity added in the tail (same side) of an executed market order. For example, a buy trade with DOM support means contracts were added at the best Bid right after the order was executed.

Market-Limit orders are commonly used by institutional traders. A Market-Limit order executes at the best available price, and if only partially filled, the remaining quantity becomes a limit order at the specified price. The limit portion provides price support (for buys) or resistance (for sells).

To spot Market-Limit orders, enable the DOM support filter and also enable Smart/Predatory and Aggression: min ticks = 1 in Extra Filters.

When Show DOM support is enabled, DOM support is visualized with triangles in the same color as the trade marker.

Aggression (Sweep) Filter

An aggressive trade consumes liquidity across two or more price levels to get filled. Aggressive trades can be:

  • Initiative market orders sweeping through multiple levels
  • Triggered stop-market orders causing a stop run
  • Also called trades with a sweep

Aggressive trades are shown with a dotted contour on the marker.

The aggression filter measures the sweep range in ticks:

  • Aggression: min ticks — minimum sweep range (default: 2)
  • Aggression: max ticks — maximum sweep range; set to -1 for unlimited (default: -1)

Tip: Use the Bar marker type to clearly see the full price range of aggressive trades.

Smart/Predatory Trades

A smart/predatory trade consumes all available liquidity on the best bid or ask. The frequency of smart/predatory trades depends on the instrument.

Enable the Smart/Predatory: enable filter to show only trades that fully sweep the top-of-book liquidity.

Selection Filter

The Selection filter limits the number of visible trades based on percentage criteria. It is applied on top of the main filters.

TypeDescription
PercentOfVolumesOnly trades within the top N% of volumes are shown. The maximum trade volume is 100%. Example: with 68%, only trades with volume between 68–100% of the largest trade are displayed
PercentOfNumberOnly the top N% of all trades (by count) are shown. Use small values (1–0.01%) because there are typically thousands of trades on a chart

Marker Size Relative To

Controls what value determines the size of trade markers:

ValueDescription
VolumeMarker size is proportional to the trade's volume
IcebergMarker size is proportional to the detected iceberg volume
DOMpressureMarker size is proportional to the DOM pressure value
DOMsupportMarker size is proportional to the DOM support value

When set to Volume, the Max number of trades in chart frame setting is available to limit marker density. This setting has priority over all filters.

Trades Volume Profile

Displays a volume profile built from trades that are currently visible on the chart. The profile is linked to the Marker size relative to setting — for example, set it to Iceberg to build an Iceberg Volume Profile. In that case, icebergs at the offer side appear as sell volumes and icebergs at the bid side appear as buy volumes.

Note: The Iceberg filter must be enabled in the Filters category for the Iceberg VP to work.

Color Modes

Controls how trade markers are colored:

ModeDescription
SolidUniform selected color for all markers
SaturationColor intensity scales with value — larger trades are more saturated. 4 saturation presets available
HeatmapMulti-color gradient from cool to hot based on trade values
GrayScaleHeatmapMonochrome intensity gradient

Pop-up Info

A floating window that shows all parameters of a trade when hovering over its marker. The pop-up displays trade volume, side, iceberg volume, DOM pressure, DOM support, aggression range, price levels, and timestamps.

Enable Order ticks to sort tick data by volume within the pop-up. When disabled, ticks are ordered by time as they arrive in the order flow.

When the Tape iceberg algorithm is enabled and a clip is detected, the pop-up adds a line describing it:

Clip: 5 x 57 @7510.5 (+14)

This reads as five refills of 57 contracts each at price 7510.5. The optional (+14) suffix is a trailing partial refill.

Use Cases for ES

The following presets demonstrate common mzBigTrade configurations for E-mini S&P 500 (ES). Each use case lists only settings that differ from defaults.

Color modeHeatmap
Trades Volume Profile: Showtrue

Markers sized by iceberg volume reveal where hidden orders absorb price movement. Enable Trades Volume Profile to build an Iceberg VP — a volume profile based on detected iceberg sizes. Clusters of icebergs at a price level indicate strong hidden support/resistance.

Historical Iceberg Detection (Tape)

Find refilling icebergs on historical bars, where the order book is unavailable.

SettingValue

Unlike the Hard/Soft preset above, this configuration needs no real-time data — the Tape algorithm reconstructs hidden volume from each trade's fill composition. Lower min refills to 2 to catch shorter clips at the cost of more false positives; raise min clip on liquid instruments where small identical fills occur by chance. Hover a marker to see the detected clip.

Aggressive Sweeps / Stop Runs

Identify trades sweeping multiple price levels — initiative orders or stop cascades.

SettingValue
TypeManual

Color modeSolid

Bar marker shows the full price range swept. Dotted contour indicates aggression. Sweeps of 3+ ticks (0.75 pts on ES) often signal initiative activity or triggered stop-loss clusters. Combine with mzFootprint to see the footprint of the sweep.

Smart Money / Market-Limit Orders

Detect institutional Market-Limit orders that leave a limit order residual in the book. Requires real-time or Market Replay data.

Logic = ALL requires all conditions simultaneously — the trade must be smart/predatory (sweeps all top-of-book liquidity), have at least 1-tick aggression, and leave 20+ contracts of DOM support. Triangles in the marker color show the limit-order residual. Buy-side DOM support acts as price support; sell-side acts as resistance.

Reconstruct Tape Mode

The MZpack order flow core reconstructs individual tick trades into aggregated trades. The settings below (group Orderflow) control reconstruction behavior.

SettingDefaultDescription
Reconstruct tapetrueReconstruct tape using timestamps and Level 1 (best bid/ask) events. Required for Iceberg detection, DOM pressure, and DOM support
Reconstruct tape: timestamps onlyfalseUse only timestamps for reconstruction — Level 1 (best bid/ask) events are ignored, including for live data, and trades with equal timestamps are merged. Enable to get an exact match between reconstructed historical and reconstructed live data — recommended for backtesting. Hard/Soft iceberg detection, DOM pressure, and DOM support are unavailable when enabled; the Tape iceberg algorithm still works
'Reconstruct tape' applyChartReloadChartReload — reload the chart to apply changes (minimizes memory). OnTheFly — apply changes without reloading (requires more memory). mzBigTrade only

Note: Disabling Reconstruct tape or using the OnTheFly method significantly increases memory consumption. Hard/Soft iceberg detection, DOM pressure, and DOM support require Reconstruct tape to be enabled with timestamps-only mode disabled, because they all rely on the Level 1 events that this mode discards. DOM pressure and DOM support additionally need the volumes resting at the best bid/ask, which Tick Replay does not reconstruct, so they run on live data and Market Replay only. The Tape iceberg algorithm only requires Reconstruct tape — it works in timestamps-only mode as well.

Non-Bid/Ask Data Support

Some markets (Forex, cryptocurrencies, NSE/Indian stock market) do not provide historical bid/ask data. Without it, all historical trades appear on the Bid side only.

Solution: Set Orderflow > Calculation mode to UpDownTick for these instruments.

Hybrid mode (NSE): NSE data providers do not transmit historical bid/ask data. Use Hybrid mode, which applies UpDownTick calculation for historical data and BidAsk for real-time data.

Recommendation: For Forex pairs, use the relevant futures contract (e.g., 6E for EURUSD) to get accurate bid/ask data and full order flow features.
