FreeIndicators – Gap Detector

The GapDetector is a straightforward tool that shows where the market left unfinished business. It tracks two things: true session gaps and imbalance zones created by fast, one-sided moves.

Session Gaps
When the market opens above or below the previous session’s close, the indicator marks the gap and extends it forward until price trades back through it. These areas often act as magnets or reaction points.

Imbalance Zones
Imbalances appear when price moves too quickly, leaving thin or inefficient trading behind. The indicator highlights these areas and keeps them active until the market revisits and fills them. You can run imbalances on multiple timeframes at the same time.

Flexible Logic
You decide how a zone counts as “filled”—either a simple touch or a full close through the level.

Clean Visualization
Each zone gets extended automatically, colored by timeframe, and labeled with its key price so you always know what level the market is responding to.

In short:
This indicator helps identify where the market may return, react, or complete unfinished structure—without clutter, without noise, and without guesswork.
