السلام عليكم ورحمة الله وبركاته
هذا مؤشر للماكد يقوم برسم دوائر خضراء وحمراء حسب تقاطع الماكد
والمطلوب اضافة شرط آخر لهذا المؤشر (متغير خارجي منطقي bool لحرية الاختيار)
بحيث يرسم الدوائر الخضراء عند تقاطع الماكد للاعلى بشرط ان يكون الماكد فوق الصفر مثلاً (متغير خارجي double)
ويرسم الدوائر الحمراء عند تقاطع الماكد للاسفل بشرط ان يكون الماكد تحت الصفر مثلاً (متغير خارجي double)
وهذا هو الكود

| Allows you to enter two ema periods and it will then show you at |
| Which point they crossed over. It is more usful on the shorter |
| periods that get obscured by the bars / candlesticks and when |
| the zoom level is out. Also allows you then to remove the emas |
| from the chart. (emas are initially set at 5 and 6) |
