Liquidex V1 Strategy

Liquidex V1 is a breakout scalping strategy converted from the original MQL expert advisor. It combines a range filter and a weighted moving average (WMA) to identify short‑term opportunities.

Trading Logic

  1. For every finished candle the strategy measures its range (high - low).
  2. If the candle range is smaller than RangeFilter, the candle is ignored.
  3. A WMA with period MaPeriod is calculated using closing prices.
  4. When the candle opens below the WMA and closes above it, a buy market order is sent.
  5. When the candle opens above the WMA and closes below it, a sell market order is sent.
  6. Each position is protected by a stop loss defined in StopLoss.

Parameters

  • RangeFilter – minimum candle range in price units required to trade.
  • MaPeriod – number of periods for the weighted moving average.
  • StopLoss – protective stop loss in points.
  • CandleType – candle series used for analysis.

The strategy uses Strategy.Volume as order size and reverses the position when an opposite signal appears.
