Overview
Unlike traditional fixed grids, this expert advisor increases the distance between subsequent levels using an expansion factor. It employs martingale lot scaling where volumes grow exponentially based on the number of open positions. The EA manages buy and sell grids independently and offers an optional price averaging feature to close baskets at a collective profit target. It is designed as an educational tool and lacks a hard stop loss parameter.
- Dynamic grid spacing expansion
- Exponential martingale lot sizing
