пожалуйста, помогите мне с кодом, когда я компилирую, он показывает мне eoors

вот ошибки
ExtMapBuffer1[i] = CalculateStochOnArray(MyArray,i);
RTFM, научитесь кодировать, определите свой массив ExtMapBuffer. Мы не собираемся кодировать это за вас. Мы готовы помочь вам, если вы опубликуете свою попытку (используя SRC) и суть вашей проблемы.
В следующий раз отредактируйте свой оригинальный пост, не перепостите.
Спасибо за ответ и ценное время, которое вы мне уделили, примите мои извинения по поводу нашего предыдущего разговора, у меня есть знания языка C, которые я изучал в колледже. Это не мой код, о котором я уже говорил,
Основная проблема в том, что я создал советника, имеющего 11 ошибок при компиляции, имеющего стратегию открытия покупки и продажи в одно время и проверки на 20 пунктов прибыли и закрытия ордера, теперь я просто хочу использовать стохастический индикатор с ним.
Скажем, если стохастик =>"75" или <="25", то ордер не будет открыт.
Вот код.
Пожалуйста, если вы мне поможете, пожалуйста, выложите весь код с исправлениями, спасибо.

просто нужно извлечь быстрое значение K и сохранить в интигере с именем (My_stockK)
mohsin360:
пожалуйста, помогите мне с кодом, когда я компилирую, он показывает мне eoors
Где объявлено i?
Где объявлен MyArray?
for (i =ArraySize(MyArray)-StochPeriod-1; i >= 0; i--)
приведенный выше код я взял из стохастического кода индикаторов mt4, я просто хочу извлечь показания стохастика в intiger, чтобы использовать его в моем советнике.
mohsin360:
Хорошо, продолжайте.

Быстрые K (а также D и замедление) поступают от эксперта, и вы передаете их в iStochastic - Документация MQL4
Ок, моя ошибка, я вставил коды не по порядку.
Здесь я вставляю снова, чтобы было легче понять.
