Oscillators
Force Index
Combines how far the price moved with how much was traded, to show the force behind a move.
L’idée en termes simples
A big price change on heavy activity is a forceful move; the same change on light activity is weak. Force Index multiplies the change by the volume.
Mode de calcul
Each candle: the change in close multiplied by volume, then smoothed with a 13-period average.
Force = (close − previous close) × volume
Force Index = MA(Force, 13)Comment l’utiliser
- Above zero: buyers have the force; below zero: sellers.
- In an uptrend, dips of Force Index below zero can be buying chances.
Tirer des conclusions
- New highs in price without new highs in Force Index suggest the move is running out of fuel.
Exemple
A stock rallies on rising volume and the Force Index reaches its highest level in months: a strong, well-supported move.
Les prix des exemples sont donnés à titre d’illustration.
Points de vigilance
- Uses tick volume for currencies and CFDs.
