http://crypto-prices.com/QTLTo answer some of the questions above... I will be making a tutorial video for the new Quatloo trader , v2.0. After the release Monday night, there will be quick updates over the following week for new function additions that had to wait because I was completely busy just getting everything to work great for all 3 exchanges that already existed in the original trader as well as the extras that are obvious... lots of improvements.
For arbitrage... there will not be any auto functions for arbitrage in this first release.. Just alot of great info in the common market datagrids to do it manually till the auto work gets done. Smart auto functions are also going to be added asap.
Regarding Mac versions .. sorry. Maybe I should have coded it in Java but i didn't. I wasn't aware that mac is so finicky for .net mono. It works on Linux!
