Angry Bird Scalping Strategy

This strategy replicates the MetaTrader "Angry Bird (Scalping)" expert advisor using StockSharp's high level API.

Logic

  • Observes 15-minute candles and computes the highest high and lowest low over the last Depth bars to derive a dynamic grid step.
  • When no position is open and the previous candle closes above the current one, RSI on the hourly timeframe triggers entries: values above RsiMin open short positions, values below RsiMax open long positions.
  • If a position exists and price moves against it by at least the grid step, a new position is opened in the same direction with its volume multiplied by LotExponent until MaxTrades is reached.
  • A strong CCI reading above CciDrop for shorts or below -CciDrop for longs forces all positions to close.
  • Positions are also closed when profit reaches TakeProfit or loss reaches StopLoss relative to the average entry price.

Parameters

  • StopLoss – stop-loss in points.
  • TakeProfit – take-profit in points.
  • DefaultPips – minimal distance between grid orders in pips.
  • Depth – number of candles used for high/low calculation.
  • LotExponent – multiplier for subsequent order volume.
  • MaxTrades – maximum number of averaging positions.
  • RsiMin / RsiMax – RSI thresholds for entry.
  • CciDrop – absolute CCI value forcing position closure.
  • Volume – initial order volume.
  • CandleType – timeframe of working candles (default 15 minutes).

Usage

Attach the strategy to a security and start. The strategy uses market orders and manages a single net position, averaging as price moves against it.
