ColorX2MA Digit NN3 MMRec Strategy

Overview

  • Recreates the triple time frame Expert Advisor based on the ColorX2MA Digit indicator.
  • Uses a custom double-smoothed moving average indicator that mimics the original X2MA logic with selectable smoothing methods (Simple, Exponential, Smoothed, Linear Weighted, Jurik, Kaufman Adaptive).
  • Applies three independent indicator instances (12h, 6h, 3h by default); each instance can independently open or close long/short exposure according to its own settings.
  • Aggregates the desired volume of every time frame and trades the difference with market orders so the net position always matches the sum of individual signals.
  • Signals are confirmed after SignalBars consecutive bars with the same slope direction, which emulates the SignalBar shift in the MQL version.
  • Includes optional switches to allow or forbid opening/closing of long and short exposure separately for every time frame, reproducing the “Must Trade” flags of the original.

Parameters

  • A/B/C Candle Type – data type (time frame) for every indicator instance.
  • Fast/Slow Method – smoothing method for the first and the second moving average inside the X2MA clone.
  • Fast/Slow Length – period of the respective moving averages (defaults: 12 and 5).
  • Signal Bars – number of consecutive bars required before accepting a new direction (default: 1).
  • Digits – rounding precision applied to the indicator output before slope calculation (simulates the Digit input).
  • Price Type – price source used by the indicator (close, open, median, typical, weighted, simplified, quarter, TrendFollow and DeMark formulas).
  • Allow Long/Short Entry/Exit – boolean flags that control whether a specific time frame may open or close long/short exposure.
  • Volume – traded volume contributed by the time frame when it is long (positive) or short (negative).

Signals and Position Management

  1. Each time frame processes finished candles only and updates its indicator value.
  2. When the slope of the double-smoothed average turns positive (color index 0 in the MQL indicator) and remains so for the configured number of bars, the context becomes bullish:
    • Existing short exposure is closed if Allow Short Exit is enabled.
    • A long position of the configured volume is opened if Allow Long Entry is enabled.
  3. When the slope turns negative (color index 2), the context becomes bearish:
    • Existing long exposure is closed if Allow Long Exit is enabled.
    • A short position of the configured volume is opened if Allow Short Entry is enabled.
  4. The strategy sums the desired volumes from the three time frames and sends a market order for the difference with the current portfolio so the global Position always reflects the combined intent.

Notes

  • Unsupported smoothing types from the MQL library (JurX, Parabolic MA, T3, VIDYA/AMA variations) are not exposed; if required they can be mapped manually.
  • The custom indicator rounds values using Digits and works only on finished candles, avoiding intrabar repainting.
  • No built-in stop-loss or take-profit is added because the original uses MMRec money management; the Volume parameters allow manual sizing instead.
