Suelo pasar tiempo en la plataforma de inventores y siempre encuentro tesoros. Hoy encontré a un joven de 21 años.Estrategia de tendenciaAdmiro la exquisita y perfecta estructura de código del autor original, y su gran flexibilidad. La estrategia original es la versión JS, que ha sido reescrita para comodidad de los usuarios de Python.
Sinceramente, muchos principiantes dan muchos rodeos al iniciarse en el trading cuantitativo. A menudo se encuentran con problemas como órdenes fallidas, pérdidas por una mala gestión del riesgo y pérdida de datos tras reiniciar una estrategia. Más tarde, me di cuenta de la importancia de un buen marco de referencia, que puede ayudarnos a evitar muchos obstáculos. Este marco de estrategia de tendencia es una herramienta muy valiosa. Es más que una simple estrategia de trading; es más bien una caja de herramientas que proporciona funciones básicas pero cruciales como la colocación de órdenes, las órdenes de stop-loss y la gestión de datos. Solo necesitas centrarte en las preguntas clave de “cuándo comprar” y “cuándo vender”. Además, el marco es muy abierto, lo que te permite cambiar fácilmente la EMA por el MACD, el RSI o cualquier otro indicador que prefieras. ¿Quieres seguir las tendencias? Sin problema. ¿Quieres probar la reversión a la media? ¿Incluso combinar varios indicadores? Por supuesto. Esta flexibilidad es increíblemente útil; puedes modificar el mismo código para experimentar con diferentes ideas.
Hoy comparto este marco con la esperanza de que sea útil para quienes exploran la inversión cuantitativa. A continuación, se presenta una introducción detallada de cada componente de este marco, que creo les resultará útil.
En comparación con las múltiples funciones independientes utilizadas en los marcos de negociación de múltiples materias primas, este marco intenta organizar y gestionar las distintas partes de una estrategia mediante un formato de clase. Este diseño orientado a objetos no solo mejora la mantenibilidad y la escalabilidad del código, sino que también hace que los componentes de la estrategia sean más modulares, lo que facilita los ajustes y optimizaciones posteriores. El marco consta principalmente de las siguientes secciones, cada una con su propia función específica, lo que garantiza la flexibilidad y la practicidad de la estrategia.
función init
__init__Esta función es el método de inicialización de la clase de estrategia, responsable de establecer la configuración básica de la estrategia, inicializar variables y obtener información del mercado. Esta función garantiza que los parámetros necesarios se configuren antes de ejecutar la estrategia, garantizando así la fluidez de las operaciones de trading posteriores.función initDatas

_GLa función guarda localmente la marca de tiempo pasada.Función getDaysFromTimeStamp
Función saveUserDatasLocal

Este marco no solo es aplicable al mercado de divisas digitales, sino que también se puede utilizar en eltrendJudgmentEl marco se puede ampliar para adaptarse a diferentes estrategias de negociación. Además, se puede modificar específicamente para el mercado spot o contratos multivariantes, con gran flexibilidad y escalabilidad.
