أرجو من الساده الأفاضل ممن لديهم خبره فى برمجة الإكسبيرتات أن يقوموا بتعديل هذا الإكسبيرت .
طريقة عمل الإكسبيرت : يعتمد الإكسبيرت على الشراء والبيع عند تقاطع موفينج 10 مع موفينج 100 وهكذا . كل صفقه يتم إغلاقها عند التقاطع الجديد سواء كانت على ربح أو خساره ودخول صفقه جديده مع الإتجاه الجديد وهكذا .
المطلوب : إضافة متوسط 50 للإكسبيرت وإغلاق الصفقات عند تقاطع موفينج 10 مع موفينج 50 .
النتيجه : فتح صفقات مع الإتجاه عند تقاطع موفينج 10 مع موفينج 100 وإغلاق الصفقات سواء على ربح أو على خساره عند تقاطع موفينج 10 مع موفينج 50 .
وشكرا جزيلا .
