Force Index (13-bar EMA, normalized)Volume

Timeframe M1 · unit norm

What it measures

Force Index multiplies the bar's price change by its volume, producing a momentum force that combines direction, magnitude, and participation. The 13-bar EMA smooths the raw series; normalization by price × average volume makes it comparable across assets.

How Janira reads it (bullish vs bearish)

Positive values indicate that recent price advances have been backed by rising volume - buying force is present. Negative values show the reverse. The magnitude reflects how strongly volume is confirming the directional movement.

In plain language

Think of this as measuring how hard the market is 'pushing' in a direction. A big up-move on heavy volume = a strong push up. A small move on thin volume = a weak push. The 13-bar average smooths out individual noisy candles.

Scenarios

• Force Index strongly positive and rising: buyers are increasing both the size of price moves and the volume behind them.
• Force Index strongly negative: sellers are forcing price down with high participation, not just light selling.
• Force Index positive but declining while price rises: buying force is weakening even as price advances, a potential divergence.
• Force Index crossing from negative to positive: the balance of force is shifting toward buyers after a period of selling.
