    Forecast Oscillator (FOSC) attempts to forecast price movements using the Time Series Forecast (TSF) for calculation. FOSC is calculated as the difference (in percent) of the actual closing price with the TSF's value of that close. FOCS provides a zero line along with the signal line which is an Exponential Moving Average (EMA) of Forecast Oscillator. Crossover of the FOSC line and its signal line indicates that the prices are expected to rise (FOCS above the signal line) or the prices are expected to fall (FOCS below the signal line).

    FOSC = [ CCP - TSF(CCP) ] * 100

    CCP – current Close price
    TSF – Time Series Forecast
