I need an experienced MetaTrader developer to build a reliable, fully automated scalping system that runs seamlessly on both MT4 and MT5. The core idea is straightforward: capture small, quick market moves with tight spreads and rapid execution while keeping risk tightly controlled. What I already have in mind • Entry logic: fast-acting scalping signals based on price action and micro-trend confirmation. • Exit logic: configurable take-profit and dynamic stop-loss (including breakeven and trailing options). • Risk controls: lot sizing tied to account balance or fixed volume, daily loss limiter, and trading-time filters. • Broker compatibility: code must work on standard ECN accounts without requiring exotic plugins. What I need from you 1. A clean, well-commented Expert Advisor (EA) coded for both MT4 and MT5 in MQL4/MQL5. 2. An external settings file so I can fine-tune parameters without recompiling. 3. Built-in spread, slippage, and news filters to avoid bad fills. 4. A functional backtest demonstrating the strategy on at least one year of EURUSD M1 data, plus an optimization report summarizing key metrics (profit factor, drawdown, trades count). 5. Basic user guide outlining installation, parameter definitions, and best-practice recommendations. Skill set I’m looking for • Strong grasp of MQL4 and MQL5, especially order management and event handling. • Proven track record with high-frequency or scalping EAs. • Ability to present concise backtest evidence and, ideally, show a brief live or demo forward test. I’m ready to move quickly and will be available to clarify rules or tweak specifications as we go. If you have a previous scalping project you can reference, that’s a big plus. Let me know your estimated timeline and any questions you need answered before coding begins.
