Hello IGHOR!
First, great to see your project still running after so many years!
As you say on sourceforge, more exchanges are to be added soon - is it possible to add either Bittrex or even better Binance sooner than later? Especially Binance has a low fee structure which makes it great for higher-frequency trading (and I really need a stop-loss function over there

)
API of Binance is explained over there
https://www.binance.com/restapipub.html, but I have no idea how much work it is for you to implement a new altcoin exchange into QT Bitcoin Trader.
Thanks
