Mass Index

ایده به زبان ساده

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.

روش محاسبه

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))

نحوه استفاده

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

نتیجه‌گیری

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

مراقب این‌ها باشید

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