Check out the new article: Price Action Analysis Toolkit Development (Part 21): Market Structure Flip Detector Tool.

The Market Structure Flip Detector Expert Advisor (EA) acts as your vigilant partner, constantly observing shifts in market sentiment. By utilizing Average True Range (ATR)-based thresholds, it effectively detects structure flips and labels each Higher Low and Lower High with clear indicators. Thanks to MQL5’s swift execution and flexible API, this tool offers real-time analysis that adjusts the display for optimal readability and provides a live dashboard to monitor flip counts and timings. Furthermore, customizable sound and push notifications guarantee that you stay informed of critical signals, allowing you to see how straightforward inputs and helper routines can transform price movements into actionable strategies.

This EA tackles one of the toughest challenges in trading: false reversal signals. Choppy price action throws off simple pivot routines, trapping traders in whipsaws. The Market Structure Flip Detector solves this by converting ATR into a flexible bar-count filter. It ignores minor swings, captures only valid highs and lows, and then flags a bearish flip when a higher-high becomes a lower-high or a bullish flip when a lower-low turns into a higher-low. Along the way, you’ll see how to:

  • Convert ATR into a deep measure that expands in wild markets and contracts in calm ones.
  • Confirm pivots by scanning an exact number of bars on each side of a candidate high or low.
  • Maintain trend bias, so flips trigger only after the previous structure breaks.
  • Annotate signals with on-chart arrows, pivot labels, and a live stats panel that tracks flip counts and timing.

Below is a GIF demonstrating the EA’s performance on EURUSD. As each one-minute candle closes, the EA tracks successive lows until it finds a swing low that exceeds the previous trough. When that higher low appears, it drops a green “HL” arrow to mark the bullish flip. At the same moment, the header panel refreshes — here showing 12 bull flips, 1 bear flip, and an average HL interval of 108.0m — to reflect the updated counts. This clip clearly illustrates the transition from a down-structure into a potential up-move.
