Supertrend - ATR based trailing trend indicator (MT4)

Supertrend uses ATR to build a dynamic trailing stop above or below price. The line flips when price closes across it. That makes it a simple way to trade trend continuation, manage stops and filter false breakouts on MetaTrader 4.

What it shows

• Green line below price - uptrend bias. Red line above price - downtrend bias.
• Flip when candle closes across the line - potential regime change.
• Pullback holds if price tests the line and bounces.
• Optional alerts on flips, touches and new extremes.

Trade ideas

1. Trend pullback: in an uptrend buy pullbacks that hold above Supertrend and flip back up. Mirror for shorts.
2. Breakout validation: after a breakout price should stay on the confirming side of the line.
3. Trail stops: move stop to the Supertrend line for rules based exits.
4. Multi TF: use higher TF Supertrend for bias and enter on lower TF when it flips with price.

Inputs that matter
