Buying and installing an Expert Advisor
Buy an EA on ea.nostr.africa, activate your licence and run it in MetaTrader 4.
Risk warningTrading involves substantial risk of loss. Expert Advisors do not guarantee profits, and grid/martingale EAs can lose the whole account. Always test on a demo account first and only trade money you can afford to lose.

- Restart MT4, or right-click Expert Advisors in the Navigator and choose Refresh.
6Allow the licence check (WebRequest)
The EA checks its licence with our server, so MT4 must be allowed to contact it:
- In MT4 open Tools > Options > Expert Advisors.
- Tick Allow WebRequest for listed URL and add
https://ea.nostr.africa. Click OK.
7Attach the EA and start
- Open the chart the EA is designed for (M5 timeframe, a pair recommended in the product description).
- Drag the EA from the Navigator onto the chart.
- In the Inputs tab, paste your key into
LicenceKey. In the Common tab, allow live trading. - Turn on AutoTrading in the MT4 toolbar.
- The chart comment should show “Licence OK, valid until …”. The Experts log also shows the licence result.
If the internet dropsIf our server cannot be reached, the EA keeps running on its last verified licence for a limited offline grace period (up to 72 hours), never beyond your subscription end date. Whenever the licence is not valid, the EA opens no new trades but keeps managing the take-profit of trades that are already open.
8Renewing
Order the same plan again from the product page before your end date, pay and enter the reference. After approval your end date moves forward and the same key keeps working. Customers also get a reminder email shortly before the end date.
