The systems were having problems at the time I left, but that is not the main reason for leaving. I was offered better rates. So I went. As for the systems, I still have some friends there and they say things have stabilized systems wise. I guess it was a period of two weeks where they were having problems. I did like their execution system though(graybox), it is pretty fast.
All in all, prop firms seem to go through stretches were there systems are great and then all of a sudden there are some hiccups, where there just seems to be problem after problem. Sometimes it is only for a day or two, sometimes it can be for a week or more. I think hold went through that in late Aug early Sept and from what I have heard they have corrected the problem.
