CCI Woodies Strategy

Overview

This strategy trades based on the crossover of two Commodity Channel Index (CCI) lines derived from the Woodies CCI method. A fast CCI and a slow CCI are calculated on the specified timeframe. When the fast line crosses below the slow line, a long position is opened and any short position is closed. When the fast line crosses above the slow line, a short position is opened and any long position is closed.

Parameters

  • FastPeriod – length of the fast CCI indicator.
  • SlowPeriod – length of the slow CCI indicator.
  • CandleType – timeframe of candles used for calculations.
  • InvertSignals – if enabled, buy and sell rules are swapped.
  • TakeProfitPoints – profit target in price points.
  • StopLossPoints – loss limit in price points.

Notes

The strategy uses the high-level StockSharp API. Indicators are bound via Bind, and risk control is handled with StartProtection using stop-loss and take-profit levels.
