Overview

Grid Retest enters positions based on price relation to a 50-period Exponential Moving Average. If a trend reverses while a basket is active, the EA initiates a dual-mode recovery by opening a new basket in the opposing direction. It manages exits through weighted average take-profit points for each basket independently. Risk management features include a maximum grid level limit and optional martingale lot scaling. The repository lacks a README file.
