SuperTrend Buy Signal: How to Screen for Trend Reversals on NSE

SuperTrend is one of the most popular trend-following indicators among Indian traders, and for good reason — it gives clear buy and sell signals based on price action and volatility. No ambiguity, no guesswork. The stock is either above the SuperTrend line (bullish) or below it (bearish).

How SuperTrend Works

SuperTrend is calculated using two inputs: a period (typically 10) and a multiplier (typically 3). It uses the Average True Range (ATR) to create dynamic support and resistance levels around the price:

• When the stock price is above the SuperTrend line, the trend is bullish. The SuperTrend line acts as dynamic support.
• When the stock price is below the SuperTrend line, the trend is bearish. The SuperTrend line acts as dynamic resistance.
• A buy signal occurs when the price crosses above the SuperTrend line — indicating a trend reversal from bearish to bullish.
• A sell signal occurs when the price crosses below the SuperTrend line — indicating a reversal from bullish to bearish.

SuperTrend Screening Strategies

Strategy 1: SuperTrend Buy Signal (Fresh Reversal)

Catch the exact moment a stock flips from bearish to bullish:

• SuperTrend Direction(10,3) daily crossed above 0 (i.e., direction changed from -1 to 1)
• Volume > 5,00,000

This finds stocks where SuperTrend flipped bullish today with strong volume confirmation.

Strategy 2: SuperTrend Momentum (Confirmed Trend)

Find stocks in an established SuperTrend uptrend:

• Close > SuperTrend(10,3) daily
• RSI(14) daily > 55
• Close > EMA(20) daily

This finds stocks where SuperTrend confirms an uptrend, RSI shows momentum, and the price is above the short-term EMA. A triple confirmation of bullish conditions.

Strategy 3: Multi-Timeframe SuperTrend

Combine daily and weekly SuperTrend for high-conviction signals:

• Close > SuperTrend(10,3) daily
• Close > SuperTrend(10,3) weekly

When both daily and weekly SuperTrend are bullish, you are aligned with both the short-term and medium-term trend. This is where BacktestKit's accurate weekly indicator handling becomes critical — you need to know that the weekly SuperTrend value is what you would have seen on that specific day, not a retroactively calculated value.

Backtesting SuperTrend Strategies

SuperTrend strategies are among the most backtested strategies on BacktestKit. The indicator gives clear, unambiguous signals, making it ideal for systematic backtesting. Set up your SuperTrend conditions, choose your backtest period, and BacktestKit will show you exactly how many stocks triggered each day and what happened next.

Choosing the Right SuperTrend Settings

• SuperTrend(10, 3): The default and most commonly used setting. Good balance between sensitivity and reliability.
• SuperTrend(7, 2): More sensitive — gives earlier signals but more false positives. Better for shorter-term trades.
• SuperTrend(14, 3.5): Less sensitive — gives later signals but more reliable. Better for longer-term positions.

The beauty of backtesting is you do not have to guess which setting works best. Build screeners with different SuperTrend parameters on BacktestKit, backtest each one, and compare the results.
