iFractalOnArray

[Михаил]

как сделать такую функцию? или может есть уже такая?

[Рустам]

идем https://www.mql5.com/ru/code/7982 берем код индикатора и подсовываем ему свой массив вместо ценового...

[Михаил]

а можно пример: хотя для пары строчек

[Михаил]

заменил в коде high и low на close. (по скольку close также массив). но индикатор вместо 5-барных фракталов, рисует 3-х барные фрактылы. подскажите где ошибка?
