Is it possible to download and maintain different data lengths for the same stock symbol?
Yes, in order to download and maintain different data lengths for the same stock symbol, there must be multiple entries for the stock symbol in a stock database. Each entry must have a different number of months entered in the Months field. For example, If you wanted 3, 6, and 12 months of data on Microsoft (MSFT), MSFT would be entered in the database three times. One entry would have 03 in the Months field, one entry would have 06 in the Months field, and one entry would have 12 in the Months field. The Exchange field could be different on each of them. For example, Exchange on one MSFT entry could be Nasdaq, it could be History on the second MSFT entry, and it could be OldNasdaq on the third entry.
