This indicator plots an ATR-based Chandelier Exit trailing stop on the price chart. It tracks a long stop under recent highs and a short stop above recent lows, then switches direction when price crosses the opposite stop. Buy and sell labels mark those flips.

Overview
ATR Trailing Stop (demo) measures true range smoothed by a simple moving average to align with MT5 ATR semantics, multiplied by a user-defined factor. The stop ratchets upward during uptrends and downward during downtrends, flipping sides when price crosses through. It plots a colored trailing stop line and marks crossover and crossunder signals with directional triangle shapes and alerts. Inputs control the ATR period and multiplier.
- SMA-based ATR calculation matching MT5 standards
- Dynamic ratcheting stop level based on price position
- On-chart buy and sell triangle plot markers
- Configurable ATR length and multiplier settings
- Built-in alert conditions for trend flips
