Exp Super Trend Strategy

Strategy converted from MQL script Exp_Super_Trend.mq5 (ID 14269). It follows the direction of the SuperTrend indicator and reverses positions whenever the trend flips. The implementation uses StockSharp high level API and the built-in SuperTrend indicator.

The indicator calculates a dynamic support or resistance line based on ATR. When price stays above this line the trend is considered bullish, otherwise bearish. The strategy opens a long position during bullish periods and switches to a short position during bearish periods. Each flip of the indicator causes an immediate position reversal.

This approach works best in trending markets where large moves follow a breakout. It is also useful as an educational template showing how to connect an indicator using BindEx and execute market orders on completed candles.

Details

  • Entry Criteria:
    • Long: SuperTrend signals an uptrend.
    • Short: SuperTrend signals a downtrend.
  • Long/Short: Both.
  • Exit Criteria: Opposite signal from SuperTrend (position is reversed).
  • Stops: No explicit stop-loss; the indicator line acts as a trailing stop.
  • Default Values:
    • AtrPeriod = 10
    • Multiplier = 3m
    • CandleType = TimeSpan.FromHours(1).TimeFrame()
  • Filters:
    • Category: Trend following
    • Direction: Both
    • Indicators: SuperTrend
    • Stops: Indicator based
    • Complexity: Basic
    • Timeframe: Medium (1 hour by default)
    • Seasonality: None
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
