Estrategia de Acción Volátil

Esta estrategia combina un rompimiento de volatilidad a corto plazo con el filtro de tendencia Alligator de Bill Williams calculado en el marco temporal de 4 horas.

Reglas de trading

  • Entrada larga cuando:
    • El ATR de período 1 es mayor que Volatility Coef multiplicado por el ATR con período ATR Period.
    • La vela es alcista y establece un nuevo máximo de 24 barras.
    • Las líneas del Alligator están alineadas hacia arriba (Lips > Teeth > Jaw) y tanto la apertura como el cierre están por encima de la línea Teeth.
  • Entrada corta cuando las condiciones anteriores se invierten en la dirección opuesta.

Al entrar, la estrategia establece niveles de stop-loss y take-profit como múltiplos del ATR(1):

  • Stop-loss = precio de entrada ± Stop Coef × ATR(1)
  • Take-profit = precio de entrada ± Profit Coef × ATR(1)

Parámetros

  • Volatility Coef – multiplicador que compara el ATR rápido con el ATR lento.
  • ATR Period – período del ATR lento.
  • Stop Coef – multiplicador ATR para el stop-loss.
  • Profit Coef – multiplicador ATR para el take-profit.
  • Candle Type – marco temporal para el análisis principal (el Alligator usa velas de 4H).
