Mass Index
Watches the candles' range widen and narrow to warn of trend reversals.
L’idée en termes simples
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.
Mode de calcul
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))Comment l’utiliser
- The "reversal bulge": Mass rises above 27 and then falls back below 26.5.
Tirer des conclusions
- It does not say which way the reversal goes: combine it with a trend indicator.
Exemple
EURJPY daily: Mass climbs to 27.4 and drops to 26.3 while a 9-day EMA turns down: a sell signal in the classic method.
Les prix des exemples sont donnés à titre d’illustration.
Points de vigilance
- Rare signals; in calm markets it can stay quiet for months.
