I am using NT with MBTrading as well as IQFeed. I am having constant (e.g. pretty much every day) data corruption problems. First, I was trying to build a real time db of ES futures data -- I had acquired about 3 months worth and then suddenly a couple of days ago the DB was corrupted and could not be repaired.
More frequently, I will suddenly be missing a days worth or even a few hours worth of ES data. For example, my charts were suddenly just missing the entire day of 9/10. I tried several things to get the missing data to return, including repairing the database, reloading historical data, etc.
Ultimately, I had to delete the database and restart -- this resulted in the data/chart getting populated properly from IQFeed.
This problem is literally happening all the time. Is there either some way to avoid this issue or some way to resolve it? I can't be constantly deleting my MDB file and blowing away all stored data, given that IQFeed only provides 30 days of historical tick data.
Thanks
