CMO Zero Cross Strategy

This strategy trades based on zero line crossings of the Chande Momentum Oscillator (CMO). When the oscillator crosses below zero, a long position is opened. When it crosses above zero, a short position is opened. Optional stop loss and take profit levels (in points) protect the position. Entries and exits for long and short trades can be individually enabled or disabled.

Parameters

  • Volume – order volume.
  • CmoPeriod – period for the CMO indicator.
  • StopLoss – stop loss in points.
  • TakeProfit – take profit in points.
  • AllowLongEntry – allow opening long positions.
  • AllowShortEntry – allow opening short positions.
  • AllowLongExit – allow closing long positions on opposite signal.
  • AllowShortExit – allow closing short positions on opposite signal.
  • CandleType – timeframe used for calculations.

Trading Logic

  1. Subscribe to candles of the selected timeframe and calculate the CMO.
  2. When CMO crosses from above to below zero:
    • Close short positions if allowed.
    • Open a long position if allowed.
  3. When CMO crosses from below to above zero:
    • Close long positions if allowed.
    • Open a short position if allowed.
  4. Stop loss and take profit are applied using protective orders in points.

Notes

  • Trading decisions are made only on completed candles.
  • The strategy uses StockSharp high-level API and binds indicators through Bind.
