Estrategia de Ruptura de Pendiente VWAP

La estrategia de Ruptura de Pendiente VWAP observa la tasa de cambio del VWAP. Una pendiente inusualmente pronunciada sugiere que se está formando una nueva tendencia.

Las pruebas indican un rendimiento anual promedio de aproximadamente 133%. Funciona mejor en el mercado de criptomonedas.

Las entradas ocurren cuando la pendiente supera su nivel típico en un múltiplo de la desviación estándar, tomando operaciones en la dirección de la aceleración con un stop protector.

Atrae a los traders activos que buscan una exposición temprana a la tendencia. Las posiciones se cierran cuando la pendiente regresa a lecturas normales. LookbackPeriod predeterminado = 20.
