Arkadaşlar bu gördüğünüz mt 5 te adxwilder göstergesi , ben bu indikatör içindeki di+- nin kesişimlerinden alım satım sinyali üretsin istiyuorum , sadece alım ve ya satım sinyali geldiğinde alarm çalsın birde grafik üzerine al-sat ikonu koysun
metatrader yazım dili konusunda epeyce cahilim bu konuda yardımcı olabilen varsa sevinirim
