I was trying to develop a liquidity provider algo to this exchange but it's impossible to work with current rate limits.
I'm receiving the error rate limit exceeded even if i post one request every 6 seconds.
That limit is ridiculously low for developing trading bots.
Hope you will find a way to allow at least 1 order or request per second in the future, this is a very serious issue for an exchange that wants to attract liquidity and be competitive.   
Can you please write of these limits in the API page?
It sucks to lose 3 working days to code something big and then realizing it can't work because of this ridiculous low rate limit!
