Unfortunately for you, this is basically a forum for new traders, so things may get more confusing.
Best you can do is conduct some due diligence yourself, its your money at risk so you need to satisfy yourself with your choice.
Check where/if the brokers are regulated (not registered or licensed), then check the regulating authority to see if there are any warnings about them.
Disregard anyone regulated in Cyprus or some off-shore island.
That should help whittle them down to a small, manageable number that you can consider opening a demo account with
