Thanks for a huge update!
Any plans to add more exchanges, particularly hitbtc?
Sometimes I do arbitrage. For this purpose I use btc-e, bitstamp and hitbtc exchanges. But hitbtc' absence makes arbitrage more difficult.
hitBTC's trades is abnormal obviously, so it would not be supported.
I have not noticed any abnormal activity on hitbtc while trading.
Its trading volume and history seems legit.
