James Liu MetaTrader 4 Collection: Free MT4 Expert Advisor

Overview

The primary EA uses trend-following indicators for entries and provides various order management options, including trailing stops, break-even settings, and position accumulation. Risk is managed through fixed lot sizes or a percentage of account equity. The system allows for a maximum number of concurrent orders and includes a toggle to reverse trade signals. Documentation is minimal, as it serves as a personal project collection.
