What was the max amount of registered users online at the same time??
TX
While I cannot answer your question specifically, I have been trading there and have been quite happy with the service. Liquidity could always be better, but it is still adequate for my size. I've found it to be the best platform for hedging. And I've gotten good response from 'customer service' on a few occasions when I've needed, through no fault of their own. And they've had no issues with down time, freezing withdrawals, or the like.
I'd recommend giving them a try. Downside is it doesn't appear they have a native English speaker on staff, so the website is not translated all that well, and that might inhibit other westerners from using the platform? I started using them with a considerable amount of skepticism, but I've been pleasantly surprised so far ...
