用通俗的话解释

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.

计算方法

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))

如何使用

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

得出结论

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

示例

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.

示例中的价格仅作说明。

注意事项

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