Server access (automatic with the installer option)
With the “Easy setup + auto-update” box (ticked by default) there is nothing to do — the OLIMP_Updater service handles server access. If you unticked it, the terminal does not let anything set this up for you — a manual step: Tools → Options (Ctrl+O) → Expert Advisors → “Allow WebRequest for listed URL” → “Add new URL” → https://olimpex.pro (the installer puts the address in your clipboard). If you forget, the indicator shows this hint on the chart.
