You need Windows and a supported MetaTrader 5 installation. GunterChart remains alpha software; start in DEMO. Review Known issues before purchase. No unsupported portable/broker/display compatibility is promised.
- Download the Windows installer and close the MT5 terminal you want to configure.
- Open Install-GunterChart.exe. If you have several terminals, choose the intended one. The wizard installs Helper and GunterChart and shows each setup stage.
- If Microsoft Defender SmartScreen says Windows protected your PC because the app is unrecognised, choose More info. Confirm the application matches the official download, then choose Run anyway if you trust it. For a malware warning or unexpected file, stop and contact support.
- Norton or another antivirus may pause the new download for around a minute while scanning. Let the scan finish. A threat detection is different: stop and contact support rather than disabling protection.
- Setup prepares eligible saved charts and opens the selected MT5 to verify its settings. Charts using another expert advisor are preserved. If the wizard shows a remaining step, follow its instructions.
Seven-day trial: No card or purchased licence code is needed. An internet connection is required for the first successful trial registration, which starts the fixed seven-day period. Helper shows the end date. There is no automatic charge; activate a purchased licence in Helper to continue afterwards.
Already purchased? Enter the code from your purchase email in Helper and select Activate. If your email contains an older ZIP package, choose Extract All before opening GunterChartUpdater.exe, then follow Helper's installation steps. Helper is available from the Windows Start menu after installation.
Verification: Daily at 22:15 Europe/London, catch-up when MT5 is running and online; seven days from the last successful authenticated check. New risk may pause after that even during a server outage. Closing, cancelling and risk reduction remain available. Valid lifetime owners returning after months away can renew verification online without repurchase.
If the download link expires, check purchase status for a fresh link where available or contact support. A download expiry is not licence expiry. If activation fails, compare the code privately with the email and share the exact status/version, never the full code. Do not bypass signature/hash failures, overwrite newer files, uninstall as a generic repair or force-restart MT5. For a sixth PC, lost PC or inaccessible mailbox, request verified support recovery.
