Overview

The robot monitors buy and sell legs independently, opening new orders at fixed pip intervals when the price moves against existing positions. It utilizes an exponential growth factor to increase trade volumes for recovery, aiming to exit the entire basket at a calculated average price plus a take profit offset. The system includes settings for grid spacing and recovery distance, though the documentation is limited to technical disclaimers.
