re data & databases, what you are doing is more or less what I'm planning to develop for EOD data for the next couple of weeks. I was going to buy a Java app for about $200 to download the EOD data at market close, i.e. 5pm Chicago time, but I realised I had to do it myself, since I also want to facilitate keeping track of contract volumes for all markets I'm trading, which means programming half of the stuff myself anyway.
So I will download the data from my IB feed at market close, write it the data files, and run my system at market close, and then download the data from the vendors at around about 8pm Chicago time and overwrite what I got from IB - giving me cleaner data.
Looking to the future for tick data, I thought about the same thing but TickData say they only update their data once a month, so they said.
BTW what database software do you use?
