The Supertrend is one of the most popular indicators among Indian retail traders. It plots a line above or below price that changes colour when a trend reversal is detected — green for uptrend, red for downtrend. It is simple to read and provides a built-in stop loss level.
Supertrend Calculation (Default: Period=10, Multiplier=3)
Basic Upper Band = (High + Low) ÷ 2 + (Multiplier × ATR)
Basic Lower Band = (High + Low) ÷ 2 − (Multiplier × ATR)
Signal: Price closes below Supertrend line → Bearish (red)
Signal: Price closes above Supertrend line → Bullish (green)
How to Read Supertrend
- Green line below price → Uptrend — hold long positions
- Red line above price → Downtrend — hold short or stay out
- Line changes colour → Trend reversal signal — potential entry/exit

Combining Supertrend with RSI
A powerful combination: Use Supertrend for direction and RSI to time entries within the trend.
Enhanced Strategy:
Condition 1: Supertrend is green (bullish trend)
Condition 2: RSI pulls back to 40–50 (momentum dip within uptrend)
Entry: When RSI crosses back above 50 while Supertrend is green
Exit: Supertrend flips red OR RSI exceeds 75
Result: Filters out weak signals, gives better entry prices

Supertrend for F&O
Supertrend works well on NIFTY and BANK NIFTY options:
- Buy Call options when Supertrend flips green on 15-minute chart
- Buy Put options when Supertrend flips red on 15-minute chart
- Use Supertrend line as stop loss for the options position
Limitations
- Generates whipsaws in sideways markets — multiple false reversals
- ATR-based stop loss can be too wide in high-volatility conditions
- Lagging — the signal occurs after the trend reversal has begun
