The bars
The force index
The 13-bar force index is +2,723: buyers have had the upper hand.
- The last bar
- The close moved -12.70 on 5,020 volume, a force of -63,754: a normal push down, 1.1 times the average size of a bar's force here.
- How it is read
- Above zero, rises came on more volume than falls; below zero, the other way. Elder used the 13-bar line for the trend and a 2-bar line to time entries against it.
- Read it with care
- The number has no fixed scale: it depends on the market's price and volume, so compare it only with itself. Tick volume from a broker is a stand-in for real volume.
Each bar's force and the average on the last bars. The last bar is marked.

Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it. Risk warning

Price change times volume
Alexander Elder's force index multiplies each bar's change in close by its volume. A big rise on heavy volume scores far higher than the same rise on thin volume. Averaging it over 13 bars shows which side has been stronger; over 2 bars it shows short pullbacks inside that trend.
Pair it with the Elder ray calculator, compare it with on-balance volume, and size the trade with the position size calculator.
