Stock lists can be imported from a text file with just the symbols on each line.
They are saved in the ini file of the strategy in the stock list section
[StockLists]
$Nasdaq100=1,1,0.00,AAPL,ADBE,ADI,ADP,ADSK,AEP,ALGN,ALXN,AMAT,AMD,AMGN,AMZN,ANSS,ASML,ATVI,AVGO ………
If you change the symbols after $Nasdaq100=1,1,0.00, then at the next start QT will repair the file and use the new symbols. This is an easy way to change the list. You just have to make sure that you replace this list in all strategy (ini) files which use this list.
You can also just make a new list with the list editor and then edit the strategies in the strategy manager so that they use the new list.
