Oldea EA Collection: Free MT4 Expert Advisor

Overview

The EA initiates trades based on fast and slow moving average crossovers, utilizing a long-period moving average for trend filtering. It manages positions through a grid-based approach and martingale lot scaling, where distances are determined by fixed pips or the Average Daily Range. Risk management includes monetary take profit targets and stop loss settings, though the stop loss defaults to zero. The repository lacks documentation.
