Force Index Signals
Positive Force
Force > 0 = buying pressure dominates. Sustained positive readings confirm uptrend. Pullbacks to zero in uptrend = buying opportunities.
Negative Force

Zero Cross
Force crossing zero = shift in control. Bulls taking over or bears taking over. Key momentum transition point.
| Force | Trend | Meaning | Action |
|---|---|---|---|
| > 0 | Up | Bulls winning | Stay long |
| > 0 | Down | Counter-trend buying | Bounce possible |
| < 0 | Down | Bears winning | Stay short |
| < 0 | Up | Counter-trend selling | Pullback possible |
Force Divergence
Force divergence is volume-weighted divergence.
- Bullish: Price lower low, Force higher low. Selling pressure weakening.
- Bearish: Price higher high, Force lower high. Buying pressure weakening.
More meaningful than pure price divergence because it includes volume. Shows real conviction failing.

Common Mistakes
- Raw Force: Unsmoothed Force too volatile. Use 13-period EMA minimum.
- Short periods: 2-period Force very choppy. Good for scalping only.
- Force alone: Combine with price action. Force confirms, doesn't predict.
- Bad volume data: Force needs accurate volume. Use reliable exchange data.
