Force Index

A technical indicator developed by Alexander Elder which estimates the buyers' pressure during an uptrend and the sellers' pressure during a downtrend. The formula is: Force Index = (Closecurrent - Closeprevious) x Volume If the current candlestick closes higher than the previous then the Force Index will be positive. On the contrary, if it closes lower then it will be negative. The addition of Volume into the formula signifies the extent of the move either upwards or downwards.
