⚡ Flash Sync — One EA. Two Roles. Zero Lag.
Most local trade copiers make you install and manage two separate programs — one for the source account, one for the destination. Flash Sync is a single EA. Attach it to both terminals, flip one setting — Role: Master or Role: Slave — and you're done. No mismatched versions, no wondering which file goes where.
Flash Sync mirrors open positions between two MetaTrader 5 terminals running on the same Windows machine or VPS — no external server, no signal-provider subscription, no internet round-trip. Pure local file-based sync, in milliseconds.
Perfect for running a prop-firm evaluation alongside your main account, managing multiple client or personal accounts, hedging across brokers, or copying a manual strategy to a demo for testing.
🚀 Features
One EA, either role
- Same file on both terminals — pick Master (publishes trades) or Slave (mirrors them) per chart
- No version-mismatch risk, no confusion about which file belongs where
Speed & Reliability
- Trade-event driven — changes propagate instantly, plus a configurable poll interval down to 50ms
- Automatic staleness detection: if the Master terminal freezes or disconnects, the Slave pauses new trades instead of guessing
- Master→Slave position mapping survives terminal restarts — no duplicate trades after a reboot
Smart Lot Sizing
- Fixed lot, Multiplier of the Master's volume, or Equity-Ratio (auto-scales to the Slave account's balance)
- Automatic rounding to each symbol's lot step, min and max volume
Cross-Broker Symbol Mapping
- Different brokers use different names for the same instrument ( DE40 vs GER40.cash , USTEC vs US100.cash ) — map them explicitly, symbol by symbol
- Optional global suffix for brokers that append letters to symbol names (e.g. EURUSD → EURUSDm )
Filtering & Risk Control
- Copy only specific magic numbers or symbols — leave the rest untouched
- Configurable max slippage
- Reverse-copy mode to open the opposite direction of the Master
- Dedicated magic number on copied trades so Flash Sync never mirrors its own trades back into a loop
🛠 How It Works
Flash Sync uses MetaTrader's shared "Common Data" folder — the one location every MT5 terminal on your Windows account can read and write to, regardless of broker. The Master instance writes a live snapshot of its open positions there; the Slave instance reads it and stays in sync. No sockets, no ports, no third party — which is exactly why it's this fast.
