You must restart trade bot from time to time
To that I say (in a non-rant feedback kinda way): Bad memory Management, which in part, I believe to come from the huge Chat it accumulates (I know you can configure it to disable chats etc etc) because it does not have a line limit, it just keeps stacking up lines (leave the trade bot running 3-5 days straight, on aden even with just system msg's, and you'll see what I'm talking about lol).
Also, the memory footprint (120mb+) per instance for something that seems to be quite simple, is quite large for an internet app.
A note to developer: please make it functional first, then animate it if you really need to.
What I mean by that is, that we don't really need all the panel animations for a simple tradebot, since each one will take some amount of ram, and since many people don't only run one instance of the app, silverlight will just start piling up data and eventually crash.
