Ballmdr EA Collection: Free MT4/MT5 Expert Advisor

Overview

The primary MetaTrader 5 file implements Mamdani fuzzy logic, processing three Relative Strength Index (RSI) inputs to determine market entries. The collection also includes several MetaTrader 4 experts focused on grid-based money management and Fisher indicator strategies. Risk management options include percentage-based risk or fixed lot sizing. The repository lacks a README, so users must rely on the source code to understand specific exit logic and trading parameters.
