Basic Martingale EA 3

Overview

The Basic Martingale EA 3 strategy replicates the MetaTrader 5 expert advisor that combines a trend filter based on the Triple Exponential Moving Average (TEMA) with ATR-driven martingale averaging. The converted StockSharp version keeps the same risk parameters, trading window and money management logic while exposing everything through strategy parameters for optimisation.

Trading logic

  1. Signal generation – on every completed candle of the selected timeframe the close price is compared with the TEMA value. A close above the indicator opens a long basket, whereas a close below it opens a short basket. Only one direction can be active at the same time.
  2. Trading window – new baskets are allowed only between StartHour and EndHour (exchange time). If both hours are the same the window is considered always open. Set TradeAtNewBar to true to limit new baskets to one per candle, similar to the original TradeAtNewBar switch in MT5.
  3. Averaging grid – once a position exists the strategy measures the distance from the worst/ best entry price. Whenever the market moves by at least GridMultiplier × ATR, an additional order is added in the direction defined by Averaging (average-down or average-up) until MaxAverageOrders is reached. The new order size follows the chosen martingale mode (Multiply or Increment).
  4. Protective exits – optional stop-loss and take-profit levels are inherited from the first order in the basket. In addition the trailing block mimics the MT5 implementation: after TrailingStart points of profit the stop is moved to price - TrailingStop (or price + TrailingStop for shorts) and tightened by TrailingStep.
  5. Flattening – if any stop, take-profit or trailing level is touched the whole basket is closed at market and all averaging counters are reset.

Parameters

Parameter Type Default Description
CandleType DataType H1 time-frame Candle series that drives the strategy.
StartVolume decimal 0.01 Initial volume for the first order in a basket.
StopLossPoints decimal 20 Stop-loss distance in price steps. Set to 0 to disable.
TakeProfitPoints decimal 20 Take-profit distance in price steps. Set to 0 to disable.
StartHour int 3 Hour (inclusive) when new baskets can start.
EndHour int 18 Hour (exclusive) when basket creation stops.
TemaPeriod int 50 Length of the TEMA indicator.
BarsCalculated int 3 Number of finished candles required before trading begins.
AtrPeriod int 14 Period of the Average True Range indicator.
GridMultiplier decimal 0.75 ATR multiplier that defines the grid spacing.
MaxAverageOrders int 3 Maximum number of averaging orders per direction (including the initial one).
Averaging enum AverageDown Choose between averaging in drawdown, averaging in profit, or disabling extra entries.
Martin enum Multiply Select between multiplicative or incremental martingale sizing.
LotMultiplier decimal 1.5 Factor used by the Multiply martingale mode.
LotIncrement decimal 0.1 Additional volume used by the Increment martingale mode.
TradeAtNewBar bool false Restrict new baskets to one per finished candle.
TrailingStart int 100 Profit in points required to activate trailing.
TrailingStop int 50 Trailing stop distance in points.
TrailingStep int 30 Minimum improvement (points) before moving the trailing stop again.

Conversion notes

  • The StockSharp version keeps the MT5 indicator set-up (TEMA(50) + ATR(14)) and exposes the bar parameter as BarsCalculated, ensuring at least the specified number of candles before trading.
  • Volume handling honours the instrument’s MinVolume, MaxVolume and VolumeStep, so live trading respects exchange limits even with fractional martingale steps.
  • Trailing logic follows the original break-even plus trailing-step behaviour but is implemented with aggregated position data because StockSharp positions are netted by instrument.
  • Chart annotations from the MT5 expert were not ported because StockSharp already provides order and position visualisation on the chart panels.
