Best Way to Test a Broker Before Adding More Funds?

[MustardHaven]

Hi folks, my question is pretty basic. When you switch to a new broker, how do you test them before fully committing? I know about demo trading, but it does not give the full picture. I have opened small accounts with a few brokers like Titan FX, Vantage Markets, and Hola Prime Markets because I liked their trading conditions. I wanted to know if anyone else does this when choosing brokers and what methods you use to decide if a broker is good enough to start trading with a larger amount of capital.

So far, I am satisfied with the execution speed, withdrawal processing, and customer support. I just wanted to ask if there is anything else I should be checking with a small account before adding more funds. Thanks in advance.
