Robot Desiree: Free MT4 Expert Advisor

Overview

The system identifies breakouts based on configurable lookback periods and manages positions using either fixed pip-based levels or volatility-adjusted stops and targets calculated from the Average True Range. It features automated position sizing based on account risk percentage, a limit on the number of concurrent positions, and a global loss limit setting. The repository lacks a detailed README as it appears to be part of an educational coding curriculum.
