#38 Symbol change

[Ravi S Ghosh]

Often, a stocks symbol is changed and the next day you download consolidated data from the exchange, it shows a new symbol which is picked up by qtstalker as a new stock. Suppose symbol was changed from A to B on date yyyymmdd. Then qtstalker shows 2 different entries of the same stock, A with data till day before yyyymmdd and B with data from yyyymmdd till date. We need something that will merge the data when provided with 2 symbols of the stock. Even better, if it can read from a cvs file with details of symbol change and make the mergers. Here is such a file which contains symbol change information.
