Estrategia Ergodic Ticks Volume OSMA

Descripción general

Esta estrategia adapta el experto MQL5 "Exp_Ergodic_Ticks_Volume_OSMA" a StockSharp. El experto original utiliza un indicador personalizado para evaluar el momentum del volumen de ticks. En esta versión, el indicador personalizado se aproxima con el histograma MACD.

La estrategia busca incrementos o decrementos consecutivos en el histograma:

  • Dos pasos ascendentes desencadenan una entrada larga y cierran cualquier posición corta.
  • Dos pasos descendentes desencadenan una entrada corta y cierran cualquier posición larga.

Se utiliza StartProtection() para evitar conflictos con posiciones existentes cuando la estrategia inicia.

Parámetros

  • FastLength – período EMA rápido para el MACD. Predeterminado: 12.
  • SlowLength – período EMA lento para el MACD. Predeterminado: 26.
  • SignalLength – período EMA de señal para el MACD. Predeterminado: 9.
  • CandleType – marco temporal de las velas, predeterminado 8 horas.

Lógica de trading

  1. Suscribirse a las velas del CandleType seleccionado.
  2. Calcular el histograma MACD para cada vela finalizada.
  3. Si el histograma crece durante dos barras consecutivas, cerrar cortos y comprar.
  4. Si el histograma cae durante dos barras consecutivas, cerrar largos y vender.
  5. Continuar procesando con cada nueva vela.
