OnBookEvent aboneliği bazen düşüyor - böyle bir şey var mı? - Hisse senetleri, vadeli işlemler, opsiyonlar ve diğer borsa enstrümanlarının ticareti - MQL5 programlama forumu

Tek bir koltuk değneği çözümü var.

TERMINAL'in global değişkenleri aracılığıyla kendi sayacınızı oluşturun.

Aynı sembolün iki penceresinin kendi adlarını oluşturması için benzersiz bir ad düşünmeniz yeterlidir.

terminal global değişkeni.

İki sembol penceresi açmak istemiyorsanız, terminalin global değişkeninin adı olarak

büyü kullanabilirsin

Mükemmel, ancak adın ne olduğu önemli değil, birden fazla pencere varsa asıl şey benzersizdir.

İsmin benzersizliği, doğrudan sembolün adıyla ilgilidir, daha genel bir durumu kastettim.

 IntegerToString ( ChartID ()) + ":" + symbol

onlar. durumunuzla ilgili olarak (tablodaki tüm MQL programları yalnızca geçerli sembolle çalışıyorsa)

 IntegerToString ( ChartID ()) + ":" + Symbol ()

yerine

 IntegerToString ( ChartID ())

bu bir hata değil... sadece disiplin
