Esta estrategia utiliza principalmente los principios de los promedios móviles para encontrar oportunidades de contratrend cuando una acción está sobrevendida en el corto plazo. Cuando el promedio móvil rápido está por debajo del promedio móvil lento, indica que la acción está en tendencia bajista. Cuando el precio rompe el promedio móvil rápido por un cierto margen, el lado negativo es limitado y es probable un rebote.
Establezca un promedio móvil rápido como 8EMA y un promedio móvil lento como 20SMA.
Cuando la SMA está por encima de la EMA, indica una tendencia alcista.
Cuando el precio rompe la EMA por un cierto margen (por ejemplo, 2-10%), la acción está sobrevendida y es más probable un rebote.
Cuando el precio cruza de nuevo por encima de la EMA, desencadena una señal de compra.
El valor de las pérdidas se calculará en función de los valores de las pérdidas y de las pérdidas.
Se liquidan cuando el precio vuelva a cruzar por debajo de la EMA.
Utiliza los principios confiables de las medias móviles.
La rápida EMA y el margen de sobreventa mejoran la probabilidad de rebote.
Control de riesgo de stop loss y take profit personalizables.
El tamaño flexible de las posiciones se adapta a diferentes apetitos de riesgo.
Los rebotes fracasados pueden ocurrir a pesar de los márgenes sobrevendidos.
Las medias móviles tienen retraso y pueden perder los rebotes locales.
El stop loss cerca de la EMA puede ser detenido fácilmente por la volatilidad.
Se requiere un ajuste manual de parámetros que afecta mucho los resultados.
Los resultados están correlacionados con la recolección de ganado.
Añadir un filtro de tendencia para evitar las operaciones de contratrend.
Agregue un filtro de volumen para mejorar la probabilidad.
Considere el stop loss dinámico en lugar de estático.
Investiga los parámetros óptimos para reducir la dependencia.
Incorporar la recolección de stock para una mejor selección.
La estrategia tiene una lógica clara y es fácil de entender como un sistema típico de reversión de la media móvil. Las ventajas son la estabilidad y el control de riesgos, por lo que es adecuado para principiantes. Pero todavía conlleva el riesgo de juzgar mal los puntos de reversión. Las mejoras a través de filtros adicionales, paradas dinámicas, optimización de parámetros, etc. pueden mejorar la robustez.

Intro //This strategy is designed to allow you to catch the bounce or "SNAP Back" of a equity that has been in a downward trend. //Once the moving averages are in the order of 200SMA > 50 SMA > 34EMA > 20SMA > 8EMA, the strategy is setup. //Next you wait for a trigger of the closing price crossing over the 8EMA, while there is a desired gap size between the 8EMA and the 20SMA (2-10% of stock value preferred). //Exit position based on target profit reached (conservative sell half at 34EMA and engage a trailing stop loss for remainder or set static limit) or price crosses 8EMA or stop loss% //*)This code also allows you to determine your desired backtesting date compliments of alanaster //This code is the product of many hours of hard work on the part of the greater tradingview community. The credit goes to everyone in the community who has put code out there for the greater good. //The idea for the coding came from video I watched on YouTube presented by TradeStation called Snap Back - thank you guys for the inspiration. //UPDATE: I have coded the other side of the strategy to allow you to take advantage of the same set-up in an uptrend for Short plays. You can turn the up or downsides on, off, or both. //Happy Hunting! //II. Table Of Contents // 1. Define Strategy Variables // 2. Perform Calculations // 3. Display Chart Information // 4.
