Не получается раскрасить осцилятор

Не будучи особо искушенным в кодировании, решил попробовать слить два индикатора в один, а именно: индикатор чайкина я решил раскрасить наподобие MACD_4CZ. К сожалению, не хватает опыта понять, что сделал неправильно.

Результирующий код ничего не выводит.

Может я с буферами напутал?
