Forex Algos Collection: Free MT4 Expert Advisor

Overview

This primary EA implements a grid-based entry system combined with martingale lot scaling, where position sizes increase significantly via a multiplier factor after initial trades. It manages risk through global loss tolerance settings, trailing stops, and a hard stop loss, though the default value is extremely wide. The collection includes various other automated strategies such as RSI-based entries and scalping, though the documentation for the repository is minimal.
