Overview
Percent Rank Reversion enters long when the rank is below the oversold threshold and rising, and short when the rank is above the overbought threshold and falling. Open longs close once the rank rises above 50, and open shorts close once it falls below 50. Length and both extreme thresholds are user inputs. There is no stop loss.
