I want an MQL5 Expert Advisor that mirrors every position opened on one “Master” MetaTrader 5 terminal to any number of “Slave” terminals running on the same Windows machine. The copier must work locally—no cloud, DLL, or external service—so trade execution relies solely on the MT5 platform and the computer it runs on. Core requirements • Instant copy of market and pending orders, including multiple simultaneous positions in the same symbol. • Automatic closure on the Slave side whenever a position is closed or modified on the Master. • Lot size adjustment rules (fixed, proportional, or custom multiplier) that I can edit from the EA inputs. • Risk-management settings such as maximum volume per ticket, overall exposure cap, and the option to block new trades if daily loss or drawdown limits are hit. • Full support for symbol suffixes/prefixes so, for example, “EURUSD.a” on one broker maps correctly to “EURUSD” on another. Technical notes • Written entirely in MQL5 and delivered as both .mq5 source and compiled .ex5. • The EA should detect Master/Slave mode via an input switch—one file, two roles. • No external libraries beyond standard MQL5. • Must run on Windows 10 / 11 under the normal MetaTrader terminal without administrator hacks. I will test on at least four live/demo accounts with various brokers. The job is complete once every outlined feature performs reliably over a trading week and the code passes MetaEditor’s compile with zero warnings. A brief PDF or text guide describing settings and installation is the final hand-off.
