Elder's Force Index (EFL)


Elder’s Force Index (EFL) determines the amount of power used to move the price of an asset. It was developed by Dr. Alexander Elder. The indicator uses price change and volume to assess the strength of the move. A high positive force index means a strong rising trend, while a low negative force index signals a strong selling pressure.
