    Parabolic SAR (Stop and Reverse) is a trend-following indicator that can be used to set a trailing stop or determine entry/exit points. The SAR follows prices as they move up or down and indicates the "stop and reverse" points (dots) on the chart. When the dots are below prices, SAR signifies the bullish trend, when the dots are above prices, the market is bearish.

    Uptrend: SAR + Prior AF (Prior EP - Prior SAR)

    Downtrend: SAR - Prior AF (Prior SAR - Prior EP)

    where:
    EP – Highest high for an uptrend and lowest low for a downtrend, updated each time a new EP is reached
    AF – Default of 0.02, increasing by 0.02 each time a new EP is reached, with a maximum of 0.20
