The Super Passband Filter
A keen oscillator algorithm introduced by John Ehlers to perform a minimization of computational lag. It does a filtering of low- and high-frequency components with which reduces a noise effect presented on chart. It could be used to symbios with any standalone indicator to advance a profit factor as well as to build expert advisor with simple rules: buy on exit oversold zone and sell on leaving overbought area, which are dynamically adapts to the market. Best effect with using it on high timeframes.
