Effectual Trade Copier

Effectual Trade Copier (Master + Slave in One EA) — File-Based, Local, No DLLs

A simple, fast, reliable trade copier for MetaTrader 5 — one single EA that runs as either the source or the destination, selected with a single input. Attach it to your source account with Mode = MASTER and to your destination account with Mode = SLAVE . No separate files, no DLLs, no network dependency — just a local shared file bridge, ideal for copying between accounts on the same VPS.

What it does:

• Copies new positions from the Master account to the Slave account in real time (polls every 500ms by default)
• Mirrors partial closes proportionally — close 40% on the master, the slave closes 40% too
• Mirrors full closes and any later SL/TP changes (breakeven, trailing stops, manual edits) automatically
• SL/TP are re-applied relative to each account's own entry price, not copied as raw prices — so mirroring stays accurate even when master and slave fill at slightly different prices

Flexible position sizing (slave side):

• Fixed lot mapping (exact master lot → exact slave lot)
• Percentage or multiplier-based scaling
• Per-symbol overrides for fine control across different instruments

Built for multi-broker setups:

• Symbol mapping table for brokers using different naming conventions (suffixes, prefixes, etc.)
• Optional exclusion list to skip copying specific symbols entirely

Reliable by design:

• Local file bridge — no external server, no internet dependency, no DLL imports required
• Integrity-checked file reads so a mid-write file is never read partially
• Persists its own state, so a terminal restart won't cause duplicate copies or lost sync
• Ticket-based position tracking that stays accurate even through partial closes

Setup in minutes: attach this EA to your source account and set Mode = MASTER ; attach it to your destination account and set Mode = SLAVE ; configure your symbol/lot mapping on the slave side — and you're mirroring trades. One product, one file, both roles.
