Overview

PF TA isolate - MFI(14) bands 20/80 triggers a long entry when the indicator crosses above the oversold threshold of 20 and a short entry when it crosses below the overbought threshold of 80. Displayed in a separate pane below the price chart, this script serves as a technical analysis isolation test. It lacks explicit stop-loss or take-profit orders and relies exclusively on opposite signal entries to close existing positions.
