Signal Mode  (default)

When Signal Mode is enabled (Settings toggle), interaction markers and gap echoes are filtered by confidence. Only interactions where the gap was high-quality, the ML model was confident, and the outcome was decisive (REJ or BRK) appear on the chart. HOV (unclear) markers are suppressed. Low-strength interactions (price barely moved) are hidden.

When Signal Mode is off, all markers are shown (legacy behavior) for debugging/analysis.

Gap Echo  (Footprint label)

A faint dotted line + italic label that appears on a gap zone after it has been filled. In Signal Mode, high-confidence echoes stay visible for 24 hours, medium-confidence for 8 hours, and low-quality interactions are suppressed entirely. Opacity fades smoothly over the echo lifetime.

The label is prefixed with the age: e.g. 15m ago - Filled - Rejected down. This updates every 60 seconds.

Interaction Outcome Markers  (Diamond markers on candle)

A coloured diamond marker placed directly on the fill candle in the chart. In Signal Mode, only markers with sufficient confidence (ML probability + gap quality + confluence) and interaction strength (how far price moved after the fill) are shown. Nearby markers with the same outcome are clustered into zones (e.g. 3x Rejected).

Directional Bias Strip

In Signal Mode, a small bar appears in the top-right of the chart showing the aggregate directional signal from recent high-confidence interactions. It answers: "Based on how price interacted with gaps recently, is structure bullish or bearish?"

The strip only appears when there are at least 2 high-confidence interactions in the last 24 hours. No signal is better than a false signal.

Confidence Tiers

Each interaction is scored 0-100 based on: ML probability, confluence score, gap quality, and heuristic scores.
