Fairlay Vote = 3
This is similar to Nitrogen when it comes to limit. I started with 4 bitcoin limits in certain markets and soon they lowered to 2 bitcoins, then 1 bitcoin and now in that same market my limit is 0.5 bitcoin. But they paid all my money.
That's a global limit, and depends on how much risk the market maker is willing to accept. Usually a more money is added to a line once you've matched the limit amount. Exchanges don't limit people.
