Been running it for a week, it is surprisingly robust considering the problems with mtgox, and me suspending my laptop a couple of times per day.
What API configuration are you using? Do you trade or just use it to watch the market?
I installed it last weekend with git.
git clone https://github.com/prof7bit/goxtool.git
I run it just like this.
./goxtool.py --protocol=socketio --use-http
I tried other configurations, but I can't say anything good or bad considering the conditions. I wouldn't call it a controlled experiment in other words.
I traded manually with it this week a bit, and it worked fine. I changed the colors up a bit since I have 256 color xterm. Until today I was just entering trades manually but then I checked the thread and saw the _balancer so I did a git stash and a git pull and I have been playing with it this evening. Fun stuff, thanks to OP for posting the example. It's better (more complete) than what I was throwing together. A good starting point.
PS If anyone is interested, I found a book on Amazon
