Combinación de estrategias de media móvil simple y media móvil adaptativa
En este artículo se presenta una estrategia de trading cuantitativa que combina el uso de una media móvil simple (SMA) con una media móvil adaptada (ALMA). Esta estrategia combina varios indicadores técnicos para formar señales de trading para entrar y salir del mercado mediante la configuración de diferentes parámetros.
El principio de la estrategia
El núcleo de esta estrategia es una combinación de SMA y ALMA que utilizan diferentes configuraciones de parámetros. El SMA es un indicador de seguimiento de tendencias muy común, que representa la dirección y la intensidad de la tendencia de los precios mediante el cálculo de las medias aritméticas de cierre de precios durante un período de tiempo. ALMA es similar al SMA, que también promedia los precios históricos, pero agrega dos parámetros ajustables α y σ, que lo hacen más sensible a los cambios en el mercado mediante el control de los parámetros.
La estrategia comienza por calcular tres SMA, que representan tendencias a corto, medio y largo plazo. También se calculan tres ALMA, que representan medias de precios en diferentes dimensiones temporales. El SMA y el ALMA se combinan entre sí para formar un indicador multigrupo.
Además, la estrategia también introduce el Índice de Fuerza Relativa (RSI) para ayudar a juzgar la situación de sobrecompra y sobreventa. Cuando el RSI es superior a la línea de sobrecompra establecida, se considera una sobrecompra en el mercado, cuando incluso las señales de compra de SMA y ALMA pueden ser engañosas. De manera similar, cuando el RSI es inferior a la línea de venta, incluso si el indicador muestra una señal de venta, puede perderse la oportunidad de rebote.
La combinación cruzada entre los diferentes parámetros de los indicadores SMA, ALMA y RSI puede formar una señal de estrategia de negociación relativamente sensible. Al mismo tiempo, el juicio de sobrecompra y sobreventa del indicador RSI puede optimizar aún más el momento de entrada y reducir la probabilidad de fijación.
Dos, las ventajas estratégicas
La mayor ventaja de esta estrategia reside en la utilización de combinaciones flexibles de parámetros indicadores. Tanto SMA como ALMA pueden ajustar los parámetros de forma flexible, representando diferentes formas de línea mediana. El RSI también puede controlar la frecuencia de la señal mediante el ajuste de los parámetros.
En comparación con un solo índice SMA, ALMA aumenta la sensibilidad a los cambios en el mercado y puede responder más rápidamente a las inversiones de tendencia. Y el juicio auxiliar del RSI también evita aún más seguir ciegamente las señales de la línea de paridad. Por lo tanto, la estrategia en general tiene una mayor capacidad de adaptación y optimización.
Otra ventaja es la variedad de fuentes de señales de la estrategia. La combinación de SMA y ALMA en diferentes dimensiones temporales interactúa, lo que proporciona una referencia de múltiples niveles para la estrategia. Esto puede filtrar el ruido aleatorio del mercado, lo que hace que la señal sea más confiable.
En general, los parámetros de la estrategia son flexibles, la señal de salida es estable y se adapta a las transacciones cuantitativas de diferentes variedades.
Tercero, el riesgo potencial.
A pesar de las ventajas de esta estrategia, existen algunos riesgos que deben tenerse en cuenta en la práctica.
En primer lugar, es el problema de la optimización de la configuración del indicador. SMA, ALMA y RSI pueden ajustar libremente los parámetros, pero la regulación inadecuada puede ser excesivamente optimizada y no puede adaptarse a los cambios estructurales a largo plazo del mercado. Esto requiere un ajuste cuidadoso de los parámetros según las características de las diferentes variedades, y no se puede buscar un efecto a corto plazo.
En segundo lugar, las señales estratégicas pueden estar rezagadas. Si bien ALMA responde más rápido que SMA, existe un cierto retraso. En un mercado que cambia rápidamente, esto puede provocar que se pierda el mejor momento de entrada.
Por último, también hay que tener en cuenta la difícil intersección que trae la combinación de varios indicadores. En algunos casos, los diferentes indicadores pueden indicar señales contradictorias. Esto debe resolverse de acuerdo con las reglas de prioridad que son claras en la experiencia.
En resumen, la estrategia no es perfecta y en la práctica aún requiere ajustes y optimizaciones constantes. Pero su configuración de parámetros flexible y sus ventajas en combinaciones de múltiples indicadores la convierten en una opción de estrategia cuantitativa que se puede aplicar a largo plazo.

//The plotchar UP/DOWN Arrows is the crossover of the fastest MA and fastest IIR MAs
//
//The dots at the bottom are the two simple averages crossing over
//
//The count over/under the candles is the count of bars that the SMAs on their
//respective resolution are fanning out.
//
//The colored background indicates a squeeze, lime=kinda tight : green=very tight squeeze. based on the 3 IIRs
//
//To answer my own question in a forum, looking at the code, i couldn't figure out how to get it from another timeframe
//and run the same calculations with the same results. My answer in the end was to scale the chosen MA length
//in the corresponding CurrentPeriod/ChosenMAPeriod proportion. This results in the same line in the same place when browsing through the
//different time resolutions. Somebody might find this invaluable
//
//The counts are for MA's fanning out, or going parabolic. Theres IIRs, Almas, one done of the other. A lot.
//The arrows above and below bars are from standard RSI numbers for OB/OS
//
//The IIRs changes color depending on their slope, which can be referenced easily with a variable.
//
//The backgrond on a bar-by-bar basis is colored when 2 sets of moving averages are in a squeeze, aka
//when price is consolidating.
//
//This aims to help the trader combine conditions and entry criteria of the trade and explore these options visually.
//They detail things from all time-frames on the current one. I prefer it because of the fractal nature of price-action, both large and small,
//either yesterday or last year. For best results, go long in short-term trades when the long-term trend is also up.
//and other profitable insights. This is also a great example of an automation algorith.
//
//The pretty ribbon is my script called 'Trading With Colors'. Use them together for fanciest results. 55/233 is my Fib Cross (golden/death) Compare it to the classic 50/200 if
//you get bored. I believe it simply works better, at least for Crypto.
//
//Evidently, I am a day-trader. But this yields higher profits on larger time-frames anyways, so do play around with it. Find what works for you.
