Overview
Greeffer BB Strategy opens a short when price crosses above the upper band and the 14-period RSI is above 80, and opens a long when price crosses below the lower band and RSI is above 30. Shorts close on a cross under the lower band, and longs close on a cross above the upper band. Length and the band multiplier are the main settings. Each order uses a percent of equity, pyramiding is allowed, and there is no stop loss. It plots strategy equity in a separate pane.
