Обернуть Python в C ++ DLL для использования в MQL4 ⇐ C++

[Anonymous]

Я пытаюсь создать dll из Python для использования в MQL4 EA . Я знаю, что могу использовать что -то вроде ZMQ, чтобы назвать Python, но это не работает, так как вы не можете использовать сокеты в бэк -тестировании. У меня есть файлы Folliwing, которые выполняют компиляцию и создают файл .exe . Когда я прикрепляю EA к диаграмме и смотрю на вкладку DLL и разбавляю, показывает, что в списке функции add_me , однако, когда я запускаю EA, не может найти 'add_me' в 'trading_functions.exe' и dlltest eurusd, h4: upressed import -функция Call>. /> trading_functions.py
