How to update safely.
A new version takes about two minutes to install. Your licence and settings stay exactly as they are — same file name, nothing to re-enter.
The same thing, in words
Make sure you're flat
Open your portal and check the account shows 0 open positions. If a grid is open, wait until it closes — then update any time. Never replace the file mid-trade.
Download the new version
In the portal, tap “Download latest EA” and unzip it. You'll get BACGoldEA_Filter.ex5.
Close MetaTrader 5
Fully quit MetaTrader 5 (on your VPS or PC) so the old file isn't in use while you replace it.
Replace the file
In MT5's data folder, go to MQL5 › Experts and copy the new BACGoldEA_Filter.ex5 in, overwriting the old one. Same file name means your chart, inputs and licence all stay exactly as they were. (Tip: in MT5 use File → Open Data Folder to find MQL5 › Experts.)
Reopen and confirm
Start MetaTrader 5 again. It loads the new version automatically — check the EA panel on the chart shows the new version number and LIVE — READY, and that Algo Trading is on. Done.
