Mass Index

الفكرة بكلمات بسيطة

Before many reversals the high–low range first widens (a "bulge"). The Mass Index sums a smoothed ratio of the range over 25 candles to spot that bulge.

طريقة الحساب

E1 = EMA(9) of the range, E2 = EMA(9) of E1; Mass = the sum of E1 ÷ E2 over 25 candles.

Mass = Σ₂₅ (EMA(H − L, 9) ÷ EMA(EMA(H − L, 9), 9))

كيفية الاستخدام

• The "reversal bulge": Mass rises above 27 and then falls back below 26.5.

استخلاص النتائج

• It does not say which way the reversal goes: combine it with a trend indicator.

ما يجب الانتباه إليه

• Rare signals; in calm markets it can stay quiet for months.
