Heatmap & Order Flow

Order-flow plugins: signals, thresholds and evidence

Set up detectors and interpret candidates without confusing them with confirmed orders.

Plugin signals and setup links
01Enable Order Flow

What it does

Enable the extension calculations.

How to use it

Wait for a complete observation window.

02Chart markers

What it does

Show detected candidates on the heatmap.

How to use it

Turning markers off is different from disabling the extension.

03Iceberg candidate

What it does

Detect replenishment alongside executions.

How to use it

This is inferred activity, not proof of a hidden order.

04Absorption candidate

What it does

Detect size executing within a constrained price span.

How to use it

Adjust window, volume and span together.

05Sweep pattern

What it does

Detect progressing executions across prices.

How to use it

Requires the configured span and directional progression.

06Volume burst

What it does

Detect an execution-volume event above the threshold.

How to use it

Tune thresholds to the instrument.

07Book imbalance

What it does

Compare available bid and ask depth quantities.

How to use it

Positive means more displayed bid liquidity.

08Liquidity change

What it does

Compare quantities at matched prices in consecutive snapshots.

How to use it

Not a pure cancellation counter; executions can reduce depth too.

09Window / Minimum volume

What it does

Set observation duration and directional volume floor.

How to use it

Long windows can combine unrelated trades.

10Refill samples / Executed–visible ratio

What it does

Tune the iceberg-candidate evidence requirements.

How to use it

Raise thresholds for fewer candidates.

11Activity

What it does

Inspect price, time, side and measured evidence.

How to use it

Selecting an observation centers its price.

12Setup guide

What it does

Open the matching Help Center guide.

How to use it

Review data-quality limitations before interpreting signals.

Open plugin settings

Open Plugins beside the heatmap controls. Signals enables individual detectors; Activity lists observations and evidence. Heatmap appearance remains in Heatmap settings.

Calibrate the detectors

Iceberg candidates compare repeated liquidity replenishment with executions. Absorption candidates compare executed volume with limited price movement. Sweeps look for directional executions across levels. Volume bursts compare size with configured thresholds. Book imbalance compares available bid and ask quantities.

Data quality and limitations

Candidate signals are inferences from captured data. They do not prove hidden order identity or intent. Sampled depth can miss intermediate events. After a feed gap, wait for a complete observation window before comparing patterns. Use the calibration and data-quality guides in this collection for detector-specific rules.
