Предполагается, что этот бот покупается на основе уровней поддержки и сопротивления, а стоп-лосс - на уровне сопротивления скользящих средних. Когда я проверю это, он не будет ничего пытаться. Как мне отладить это, чтобы сделать то, что я хочу?
После просмотра кода у вас есть какие-либо пожелания или замечания?
Я попытался прокомментировать код как можно лучше.
