Specification
I am looking for an expert MQL5 developer to build a high-precision Hedging System between two different MT5 brokers running on the same local PC.
Core Objective:
Execute opposite (inverse) trades between a Master and Slave account (e.g., Master BUY = Slave SELL, Master SELL = Slave BUY).
The Challenge:
Standard "Trade Copiers" are insufficient as they cannot prevent single-legged exposure when using manual trading buttons. I require a robust "Gatekeeper" architecture to manage execution.
Technical Requirements:
Custom Trading Panel: I require an on-chart GUI with 'BUY' and 'SELL' buttons on the Master. This panel will be the exclusive way to execute trades. The system must NOT attempt to intercept native MT5 trade buttons.
Universal Chart-Based Mapping: The tool must not rely on hardcoded symbol lists or complex mapping tables. Instead, the EA will be placed on the chart of the symbol I wish to trade on both terminals. It should automatically detect the symbol from the chart it is attached to (e.g., if I attach it to EURUSD on the Master and EURUSD.r on the Slave, it should seamlessly link these two without any manual configuration).
Synchronous Inverse Logic: When a button is clicked, the system must calculate price quotes on both terminals simultaneously. If the price difference is within my limit [X], it must execute the opposite positions in both terminals at the same microsecond.
Zero Exposure Policy: If the connection between terminals (Named Pipes) is unstable, or if the Slave execution fails/price deviation is too high, the system must BLOCK the execution on BOTH terminals entirely. I prefer to miss a trade entirely than to be exposed with only one leg.
Full Synchronization: SL, TP, and partial closes must be mirrored inversely in real-time, regardless of the symbol name or broker suffix.
Expectations:
Please do not propose a standard signal copier. I am looking for a developer who understands synchronous hedging architecture and IPC communication.
If you have built such a tool before, please share your approach to ensuring synchronous execution and how you handle latency/naming differences between two brokers.
The delivered code must be clean, modular, and optimized for performance.
"Budget is negotiable based on the developer's experience and the quality of the proposed architecture."
