Reversals With Pin Bars Strategy

Overview

This strategy is a C# port of the MetaTrader expert advisor "Reversals With Pin Bars". The original EA searches for long-tailed rejection candles (pin bars) and confirms them with a momentum filter, a higher timeframe linear weighted moving average (LWMA) trend check, and a MACD direction filter. The port keeps this multi-timeframe structure, relies exclusively on StockSharp indicators, and exposes the most important risk controls as parameters.

The implementation focuses on the high-level StockSharp API: candles from the primary timeframe drive entries, while additional subscriptions feed higher timeframe indicators. Risk management is expressed in pips and supports optional trailing-stop and break-even automation.

Entry Logic

  • Pin bar detection: The previous finished candle must have a wick that represents at least 50% of its full range.
    • Long setup: the upper shadow is dominant (matching the original "hanging man" check).
    • Short setup: the lower shadow is dominant.
  • Trend filter: Fast LWMA (length = FastMaPeriod) must be above/below the slow LWMA (SlowMaPeriod) on the higher timeframe.
  • Momentum filter: The absolute distance of the momentum value from 100 on any of the last three higher-timeframe bars must exceed MomentumThreshold.
  • MACD filter: MACD main line must be above/below the signal line on the MACD timeframe.
  • Position limits: Net exposure cannot exceed MaxTrades * Volume. New trades use the aligned Volume setting.

Risk Management

  • Stop-loss / Take-profit: Fixed distances in pips (StopLossPips, TakeProfitPips) from the entry close.
  • Break-even: When enabled, the stop moves to entry ± BreakEvenOffsetPips once price advances by BreakEvenTriggerPips.
  • Trailing stop: When enabled, trailing keeps a distance of TrailingStopPips from the latest close.
  • Automatic flattening: Reaching the calculated stop or target exits the entire position with a market order.

Parameters

Parameter Description
TradeVolume Volume used for each new entry, aligned to the instrument step.
MaxTrades Maximum number of same-direction entries (aggregated volume limit).
StopLossPips Stop-loss distance in pips.
TakeProfitPips Take-profit distance in pips.
EnableTrailing / TrailingStopPips Enable and configure the trailing-stop distance.
EnableBreakEven / BreakEvenTriggerPips / BreakEvenOffsetPips Break-even activation and buffer settings.
FastMaPeriod / SlowMaPeriod Lengths of the higher timeframe LWMAs.
MomentumPeriod / MomentumThreshold Momentum length and minimum absolute distance from 100.
MacdFastPeriod / MacdSlowPeriod / MacdSignalPeriod MACD configuration for the long-term filter.
CandleType Primary candle series for pin bar detection.
HigherCandleType Candle series used for LWMAs and momentum.
MacdCandleType Candle series used for MACD.

Differences vs. the MetaTrader Version

  • Money-based take-profit, trailing, and equity stop options were omitted; risk is expressed via pips.
  • Fractal-line confirmations that required chart objects were replaced by indicator-based conditions.
  • All notifications (alerts, emails, push messages) are removed; the StockSharp version focuses on trading logic.

Usage Notes

  1. Assign the strategy to a portfolio and security, then adjust the three candle types to match your desired multi-timeframe setup.
  2. Ensure the instrument price step reflects the pip definition (default fallback is 0.0001).
  3. Start the strategy; stops, targets, trailing, and break-even management are performed automatically on candle close.
  4. Monitor results; adjust momentum and LWMA lengths to fit the instrument volatility profile.
