I've moved the backtester onto another server for now. The original server seems to have developed instabilities over time. Normally, this means a harddisk is going down, but this time this was not the case. Also, the server was very stable when I tested the machine under heavy loads without disk IO. As a final test I had to pull out the harddrive and test it on another system to verify that the harddrive was not to blame. That leaves the motherboard as the primary suspect, and the chipset responsible for handling disk IO. Over time the machine started going down, first once every month, then every week, then every day and lately every minute. You get the picture.

Anyway, I've moved the backtester and picks over to a more modern system which should hopefully be able to handle it for a while without any trouble. I have disabled the links to the older sites as part of this process, but if there are certain articles you want to access send me an email and I will see if I can pull it out for you. I may or may not put the older sites back online later.

Thank you for your patience.
