Нужна помощь в переделке индикатора (в место стандартной синусойды отрисовывает прямоугольную синусойду)

 

Должно быть вот так (мт4)

вот сам рабочий код (мт4)

Игорь:

Должно быть вот так (мт4)

вот сам рабочий код (мт4)

вот, что у меня получается в мт5

вот код в мт5

В МТ5 iMA возвращает хендл индикатора, а не значения. И должно использоваться в функции OnInit. А в функции OnCalculate используем CopyBuffer

код стал править "и началось в колхозе утро")

Ну всё код подправил ошибок и предупреждений нет. Однако выявил разницу в отрисовки индикатора.

должно быть так


после переделки на мт5, выглядит так

вот сам код (возможны ошибки по логике)
