Puria Method Strategy

Overview

The Puria Method strategy is a trend-following system originally designed for MetaTrader. It combines three moving averages with a MACD trend filter to detect momentum breakouts. The StockSharp conversion keeps the original entry logic and adds modern risk controls such as partial profit taking and automated trailing stops.

Trading Logic

  • Calculate three moving averages using configurable smoothing methods and price sources.
  • Evaluate the difference between the slower baseline MA and the two faster MAs on the previous bar. A bullish signal requires both fast MAs to be at least 0.5 points above the baseline; a bearish signal requires the baseline to lead by the same margin.
  • Confirm market direction with the MACD main line. Long trades require the previous MACD value to be positive and the recent MACD history to be non-decreasing for the configured number of bars. Short trades require the opposite conditions.
  • When an entry is triggered the strategy closes an opposite position (if any) and opens a new net position in the signal direction.

Risk Management

  • Stop Loss / Take Profit: Prices are calculated from the entry using pip distances and normalized to the security price step.
  • Trailing Stop: Once the position moves beyond the trailing threshold plus step, the stop is advanced with every additional trailing step.
  • Partial Exit: After the price travels a minimum profit distance a configurable fraction of the position is closed to lock in gains.
  • Position Management: The algorithm keeps track of the highest (long) or lowest (short) price after entry to trigger stop or profit rules when candles pierce those levels.

Parameters

Name Description
StopLossPips Stop loss distance in pips.
TakeProfitPips Take profit distance in pips.
TrailingStopPips Trailing stop distance in pips.
TrailingStepPips Minimum profit advance before the trailing stop is updated.
MinProfitStepPips Minimum distance in pips before taking a partial profit.
MinProfitFraction Fraction of the position to close when the minimum profit step is reached.
CandleType Primary candle series used by the strategy.
Ma0Period, Ma1Period, Ma2Period Periods for the three moving averages.
Ma0Shift, Ma1Shift, Ma2Shift Optional bar shifts applied to each moving average.
Ma0Method, Ma1Method, Ma2Method Moving average smoothing methods (simple, exponential, smoothed, linear weighted).
Ma0Price, Ma1Price, Ma2Price Candle price sources for the moving averages.
MacdFastPeriod, MacdSlowPeriod, MacdSignalPeriod MACD configuration.
MacdTrendBars Number of bars used to verify the MACD monotonic trend (minimum 3).
MacdPrice Candle price source for the MACD calculation.

Notes

  • The strategy uses the previous completed bar for MA and MACD comparisons to avoid relying on unfinished candle data.
  • Pip size is automatically derived from the security price step and decimal precision.
  • Trailing and partial exit features require non-zero configuration values; otherwise the corresponding blocks remain inactive.
  • The converted version relies solely on finished candles (CandleStates.Finished) and should be paired with a candle series that matches the original chart timeframe.
