Estrategia VWAP Reversion

Estrategia VWAP Reversion que opera en desviaciones del Precio Promedio Ponderado por Volumen

Las pruebas indican un rendimiento anual promedio de aproximadamente 127%. Funciona mejor en el mercado de acciones.

VWAP Reversion opera en desviaciones del precio promedio ponderado por volumen. Si el precio se aleja demasiado por encima o por debajo del VWAP, la estrategia opera contra el movimiento y sale al recuperarse.

Dado que el VWAP refleja los niveles de transacción típicos, las desviaciones extremas a menudo atraen el precio de vuelta hacia él. Algunos traders combinan esta señal con filtros de tendencia intradía para mayor probabilidad.
