That's for sure!
Exness are a dodgy Russian outfit whom many in the industry consider to be out-and-out crooks.
Tickmill and HotForex both promote themselves in forex forums by paying people to mention them favourably in posts, and that tells you exactly what sort of customers they want to attract, which in turn tells you all you need to know about how they do business. Keep away!
I haven't heard of anything terrible about IC or Pepperstone, though, so I'd try one of those.
How, where, and by whom they're regulated and what their regulatory record is are the things that actually matter.
Like Lukas (above) I've been around the industry for some decades and would by now probably be aware of it if there were anything seriously wrong with either IC or Pepperstone. But stay well away from Hotforex and Tickmill (even though Tickmill is now allegedly FCA-regulated).
By any objective or sensible standards, this is just plain ridiculous.
