The creators of the cTrader trading platform (Spotware) released an open beta version of the platform for their users to test on a demo account to identify any bugs before it is rolled out to brokers. This is a controlled group where feedback is given back to the developers, this is not a version of the platform to live trade with.
The Purpose of cTrader Beta
The reason Spotware publish a beta version is to test performance and identify any bugs that the platform may have, beta testers can test in-depth far more than the testing team at Spotware as there are thousands of testers.
Do not use a live account with the beta version of cTrader.
