Expert MQL4 Developer Needed for Advanced Grid EA with Salami Liquidation Engine

MQL4 エキスパート 売買ロボット/指標のデバッグ 統計と数学

指定

Project Overview: I am looking for a highly experienced MetaTrader 4 (MQL4) developer to build a sophisticated automated trading system. This is not a standard grid bot; it requires complex trade management, dynamic exposure rebalancing, and a custom "Salami" liquidation module for partial loss mitigation .

Key Features to Implement:

  • Virtual Grid & Dynamic Trend: Price-action-based grid triggers without pending orders . Includes a reversal mechanism that swaps "Trend" and "Counter-Trend" roles instantly based on price movement .

  • Salami Liquidation Engine: A cascading partial-close system that uses a percentage of net profits to systematically "chip away" at the oldest losing positions .

  • Ticket Inheritance Logic: Expert handling of ticket IDs after partial closes to maintain the "Virtual Age" of positions for oldest-debt tracking .

  • Nominal Value Rebalancing: Dynamic lot calculation to balance the total nominal value (Long vs. Short) based on specific coefficients .

  • News & Safety Filters: Integration with an economic calendar API for High Impact (Red) events, including "Smart Exit" and "Hard Stop" sequences before news release .

  • Strict Lot Normalization: Custom rounding-up logic (MathCeil) to ensure all calculated lots meet broker-specific step requirements .

  • Multi-Pair & Multi-Magic Ready: The code must strictly separate data by Symbol and Magic Number to allow simultaneous trading on multiple pairs .

Developer Requirements:

  • Proven experience in complex MQL4 projects (handling partial closes is a must) .

  • Experience with WebRequest for external API integration .

  • Strong focus on logging and error handling (Every Salami step must be logged).

Testing & Delivery Requirement:

  • 24-Hour Live Demo Test: Before final milestone release, I require a 24-hour testing period where the EA runs on a live Demo account (e.g., GBP/USD).
