Apologies to everyone for being so quiet the last few days, I've been hip-deep in code, working on a new version of Ultra-Arb. I have now released this version - I'm still making changes and adding things, but feel free to use it, and publicize it. Please note that I took UTC off Poloniex, because it was delisted.

And the new Coin360 page:




I have not yet tested this on all browsers, but that's my next step. along with tightening up and tweaking the UI, and verifying the "recommended # of coins" algorithm is working correctly.
