Supertrend is a popular trend-following indicator that plots a single line either above or below price, indicating the current trend direction. When price crosses the Supertrend line, the line flips position and color, generating buy and sell signals. It’s widely used in Indian markets for its simplicity and effectiveness in trending conditions.
- Line below price (green) = uptrend (buy signal)
- Line above price (red) = downtrend (sell signal)
- Uses ATR to adapt to volatility
How Supertrend Works
Supertrend uses ATR to create dynamic bands:
Supertrend Calculation:
Settings: 10-period ATR, 3x multiplier
Upper Band = (High + Low)/2 + (ATR × 3)
Lower Band = (High + Low)/2 - (ATR × 3)
Example:
Average Price: ₹100
ATR (10): ₹5
Upper Band: 100 + 15 = ₹115
Lower Band: 100 - 15 = ₹85
If in uptrend: Line at ₹85 (support)
If in downtrend: Line at ₹115 (resistance)
Flip Trigger:
Price closes above ₹115 → Flips to uptrend
Price closes below ₹85 → Flips to downtrend
