    Force Index (FI) is a technical indicator that uses price and volume to quantify the power behind an asset's price movement. FI is calculated as the volume for a specified period multiplied by the difference between the current prices and a prior price. The high positive values indicate a strong rising trend, and low values signify a strong downward trend.

    FI1 = (CCP - PCP) * VFI13 = 13-period EMA of FI1

    CCP – current Close price
    PCP – prior Close price
    VFI – volume of Force Index
    EMA – Exponential Moving Average
