Super Trend

Strategy based on Supertrend indicator

Testing indicates an average annual return of about 67%. It performs best in the stocks market.

Super Trend calculates a dynamic line from ATR that flips between support and resistance. Price crossing above it turns the bias bullish, and crossing below turns it bearish. The trade ends when the line reverses.

By following this adaptive line, the strategy attempts to capture sustained runs while minimizing whipsaws. Because the stop level trails price, it locks in profits once momentum fades.
