Exp BrainTrend2 AbsolutelyNoLagLwma X2MACandle MMRec Strategy

Overview

This strategy recreates the multi-module MetaTrader Expert Advisor by combining three filters in the StockSharp high level API:

  1. BrainTrend2 inspiration – an Average True Range (ATR) channel detects volatility contraction and expansion phases.
  2. AbsolutelyNoLagLwma approximation – a linear weighted moving average (LWMA) tracks the dominant direction with minimal lag.
  3. X2MACandle replica – a fast and a slow exponential moving average (EMA) pair evaluates candle colour to validate momentum.

A position is opened only when all filters point in the same direction. ATR driven stop-loss and take-profit targets manage the exit process and emulate the original MMRec money management concept.

Trading Logic

  • Bullish setup: the candle closes above the LWMA while the fast EMA is higher than the slow EMA. A fresh long entry is allowed only after the previous bullish bias disappeared, preventing multiple orders on identical signals.
  • Bearish setup: the candle closes below the LWMA while the fast EMA is lower than the slow EMA. Short positions obey the same confirmation and cooldown rules as the long side.
  • Risk management: ATR defines dynamic exit levels. Both stop-loss and take-profit scale with the current volatility and are re-evaluated on every candle. If the market touches either level, the strategy closes the entire position by market order.

Parameters

Name Description
CandleType Timeframe of the working candle series. Defaults to 6-hour candles to mirror the original EA defaults.
AtrPeriod Lookback period used by the ATR volatility filter.
LwmaLength Period of the linear weighted moving average trend filter.
FastMaLength Period of the fast EMA used for candle colouring.
SlowMaLength Period of the slow EMA used for candle colouring.
StopLossAtrMultiplier Multiplier applied to ATR to calculate the protective stop distance.
TakeProfitAtrMultiplier Multiplier applied to ATR to determine the take-profit distance.

All parameters are exposed through StrategyParam<T> so that they can be optimised inside StockSharp.

Notes

  • The original Expert Advisor relies on proprietary indicator buffers. This port uses standard StockSharp indicators that reproduce the same directional cues without relying on external scripts.
  • Money management is simplified to full-position exits because StockSharp strategies typically operate on portfolio-sized orders. The ATR driven distances provide the adaptive behaviour expected from the MMRec module.
  • Commentary in the code is in English as required by the conversion guidelines.
