(PC\/VPS Downtime Behavior)"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">Even if you stop the Data Sync EA or shut down the PC\/VPS it is running on, <strong>previously synced trade history is not lost<\/strong>. While the EA is stopped, only the sync of new trades pauses for that window \u2014 once the EA starts again it automatically catches up and re-syncs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summary (3 lines)<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Past trades are stored permanently on the TraderIsMe server (Supabase), so stopping the EA or turning off your device does not delete data.<\/li>\n<li>When the EA restarts, it reads the MT4\/MT5 history and registers <strong>only unsynced tickets<\/strong> as a delta \u2014 no duplicates are created.<\/li>\n<li>You do not need to worry that &#8220;data will be lost if the EA is not running.&#8221; You can reboot your PC or VPS whenever you like.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Behavior While the EA Is Stopped<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Past data stays<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">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.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. What about new trades that happen while the EA is off?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">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 <em>when the EA restarts<\/em> 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.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. No duplicate entries<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The EA&#8217;s sync logic deduplicates using the MT4\/MT5 <code>ticket<\/code> (ticket number). If the same ticket number already exists on the server, it is skipped \u2014 so even after a long pause, the same trade will not be registered twice.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">About the Heartbeat (Connection Check)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Data Sync EA sends a &#8220;heartbeat&#8221; to the server every 60 seconds, but this exists mainly to verify <strong>whether your subscription is active<\/strong>. Even if the heartbeat is interrupted, your account is not marked &#8220;disconnected&#8221; and data is not deleted.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Operational Recommendations<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>If you want 24-hour operation<\/strong>: install the EA on a VPS. Sync stays near real-time regardless of your PC&#8217;s power state.<\/li>\n<li><strong>If you run it on a home PC<\/strong>: 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.<\/li>\n<li><strong>When resuming after a long pause<\/strong>: widen the period in the MT4\/MT5 &#8220;History&#8221; tab (e.g., &#8220;All History&#8221;) before starting the EA, and older trades will also be included in the sync.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Related: <a href=\"https:\/\/docs.traderis.me\/en\/docs\/mt-data-sync-setup\/\">Set Up MT4\/MT5 Data Sync<\/a><\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>Even if you stop the Data Sync EA or shut down the PC\/VPS it is running on, previously synced trade history is &#8230; <a title=\"Do I Lose Trade History When the Sync EA Is Off?
