Gap Finder is a lightweight indicator designed to detect and visualize price gaps that occur between trading sessions, commonly referred to as CME gaps. It is suitable for both intraday and higher-timeframe traders who monitor unfilled gaps as potential areas of interest.
🔍 How it works
- The script detects gaps on the open of a new trading day by comparing the current open to the previous session’s close.
- Gaps are filtered by a minimum gap size (%), allowing you to ignore insignificant gaps.
- Each qualifying gap is drawn as a shaded box between the gap’s high and low.
- Gaps are monitored in real time and are considered filled once price trades into the gap area (with an optional buffer).
📊 Visual behavior
- Gap boxes extend only up to the current bar (not into the future), preventing old unfilled gaps from distorting chart autoscaling.
- A configurable lookback limit (default: 100 bars) controls how far a gap remains visible on the chart.
- Optional labels display the gap size percentage at the time of creation.
- Separate colors are used for up gaps and down gaps for quick visual identification.
⚙️ Inputs
- Minimum Gap Size (%) – Filters out small gaps
- Gap Colors – Custom colors for up and down gaps
- Fill Buffer – Extra tolerance for determining when a gap is filled
- Gap Lookback (bars) – Maximum number of bars a gap is displayed
- Show Gap Size Label – Toggle percentage labels on/off
✅ Designed for usability
- Does not affect chart scaling due to old gaps
- Efficient object handling for smooth performance
- Works on intraday and daily charts
- Overlay-based for seamless integration with price action
