Как самая простая стратегия, стратегия скользящей средней очень проста в изучении, поскольку стратегия скользящей средней не имеет никаких продвинутых алгоритмов и сложной логики.

Сравнение на основе обратного теста
Мы сравнили версию JavaScript и версию Python стратегии с бэкстером.
- Бактэст версии Python
Мы используем публичный сервер для бэкстеста, и мы видим, что бэкстест версии Python немного быстрее.
- Бактэст версии JavaScript
Можно увидеть, что результаты обратных тестов точно такие же. Интересующиеся друзья могут углубиться в код, и не будет небольших выгод.
Расширить
Давайте сделаем демонстрацию расширения и расширим функцию графика на стратегию, как показано на рисунке:
Преимущественно увеличить кодирующую часть:
- Добавить члена класса " Менеджер ":
objChart - Добавить метод в класс Manager:
PlotRecords
Вы можете сравнить различия между двумя версиями и узнать идеи расширенных функций.
