اس حکمت عملی کا مرکز زیڈ اسکور کا حساب کتاب ہے۔ یہ موجودہ قیمت اور صارف کے ذریعہ طے شدہ لمبائی پر قیمت کے ایکسپونینشل موونگ ایوریج (ای ایم اے) کے درمیان فرق لے کر اخذ کیا جاتا ہے ، پھر اسے اسی لمبائی پر قیمت کے معیاری انحراف سے تقسیم کیا جاتا ہے۔
z = (x - μ) / σ
جہاں ایکس موجودہ قیمت ہے، μ ای ایم اے کا اوسط ہے، اور σ معیاری انحراف ہے.
ٹریڈنگ سگنل پہلے سے طے شدہ حدوں کو عبور کرنے والے Z- اسکور کی بنیاد پر تیار کیے جاتے ہیں:
ان خطرات کو جاری مارکیٹ تجزیہ، پیرامیٹرز کی اصلاح اور بیک ٹسٹنگ پر مبنی محتاط نفاذ کے ذریعے منظم اور کم کیا جاسکتا ہے۔
