Varsayım: Yukarıdaki koddan hacmi yanlış hesaplarsınız (daha doğrusu, böyle bir hacimle açılma olasılığını yanlış kontrol edersiniz) - bir pozisyon açtıktan sonra serbest marj yerine TOPLAM serbest marjı kullanırsınız. Ayrıca önce m_symbol.LotsLimit() içinde neyin ayarlandığını kontrol etmeniz gerekir.

Hiç okumuyorsunuz: neden bir pozisyon açtıktan sonra serbest marj yerine TÜM serbest marjı kullanıyorsunuz?

Genel olarak, makaleyi okuyun ve tekrar okuyun.
