I am one of the closed beta testers, after pushing them to let me test it out after their success stories.

I received the trading bot a few days ago and started using it on various exchanges. Yesterday I checked the balance across the five exchanges and noticed an average 10% profit (in BTC, not USD). All bots were in profit, with the exception of Kraken which was at a 5% loss, even though it had a 10% profit the day before. In the logfile I saw about 50% of the messages were about Kraken so I stopped the Kraken instance.

Just now I checked again over the 4 remaining exchanges, and I currently have a 15% profit in BTC. Sorry I don't have any fancy graphics, I have to manually check the exchanges and I haven't been bothered yet to setup their profit-tracker. But so far I'm quite happy with the result
