The Klein sample does not work properly, use the console sample and adapt it to your code. You also need a broker to authorize your CTrader account to access the OpenAPI platform. If you are in the UK, you would have your work cut out finding such a broker. Having a CTrader account for desktop or Mobile Apps do not automatically grant you access to the OpenAPI service l have found. Contact your broker to negotiate access.
