Even if you stop the Data Sync EA or shut down the PC/VPS it is running on, previously synced trade history is not lost. While the EA is stopped, only the sync of new trades pauses for that window — once the EA starts again it automatically catches up and re-syncs.
Summary (3 lines)
- Past trades are stored permanently on the TraderIsMe server (Supabase), so stopping the EA or turning off your device does not delete data.
- When the EA restarts, it reads the MT4/MT5 history and registers only unsynced tickets as a delta — no duplicates are created.
- You do not need to worry that “data will be lost if the EA is not running.” You can reboot your PC or VPS whenever you like.
Behavior While the EA Is Stopped
1. Past data stays
Once the EA has sent a trade even once, that data is saved in the server-side database. As long as your plan is active, the data will not be deleted when you stop the EA or shut down your PC.
2. What about new trades that happen while the EA is off?
If new orders are opened or closed in MT4/MT5 while the EA is stopped, those trades are picked up from the MT4/MT5 history tab when the EA restarts and are registered via delta sync. So even if you stop the EA for several hours or days, everything is reflected in a single batch when it resumes.
3. No duplicate entries
The EA’s sync logic deduplicates using the MT4/MT5 ticket (ticket number). If the same ticket number already exists on the server, it is skipped — so even after a long pause, the same trade will not be registered twice.
About the Heartbeat (Connection Check)
The Data Sync EA sends a “heartbeat” to the server every 60 seconds, but this exists mainly to verify whether your subscription is active. Even if the heartbeat is interrupted, your account is not marked “disconnected” and data is not deleted.
Operational Recommendations
- If you want 24-hour operation: install the EA on a VPS. Sync stays near real-time regardless of your PC’s power state.
- If you run it on a home PC: you can shut the PC down at night or when you go out without any issue. The EA will pick up the delta the next time you launch MT4/MT5.
- When resuming after a long pause: widen the period in the MT4/MT5 “History” tab (e.g., “All History”) before starting the EA, and older trades will also be included in the sync.
