Elder's Force Index (EFI)

Elder's Force Index (EFI)

Elder's Force Index (EFI) measures the power behind a price movement using price and volume. The indicator can also be used to identify potential reversals and price corrections. The EFI is an oscillator that fluctuates between positive and negative values, above and below a Zero Line. Alexander Elder, the indicator's creator, believed that there are three components to a security's price movement. Those three components are; direction, extent and volume. All three of these components are combined by the EFI to generate the oscillator.
