Set "Use Only Local database" flag programatically

Hi,

I have created a local database and use a third party plugin for RT data feed. Limitation of plugin is of 200 tickers at a time, whereas the number of tickers I create in the database range between 500-600. These are weekly options. Database is for one month. So at a time only 1/4th of total symbols require RT feed. I import these tickers through the 'Import Ascii' option from a csv file.

I am trying to set the 'Use Only Local database' option for every symbol to 'Yes' while using 'Import ASCII', but failed. I tried creating a separate format file with $USEONLYLOCALDB 1. But even that doesn't work. Setting these manually for 400-500 tickers would be very tedious every month or every week. Is there a way to set this flag through AFL?

@madang, Not being a RT data user, this may be way off base...

Can you select in your RT dB what tickers you want for the week (month) and essentially turn the rest off?

You should use it like in the pic. attachScreenshot_1

@snoopy.pa30, unfortunately there's no such filter. The RT plugin subscribes to all the tickers that are Explored/Back tested. The only way is to create a filtered watchlist for only those symbols that need RT feed. But this invalidates my purpose of including the old ones which provide historic data back testing in the same backtest. I could do this but this would result in a lot of extra collation of data from two separate backtest results into excel and then organizing them. I was wondering if there is a way of setting the 'use local database only' flag for required symbols through AFL. Thanks.

@Muli, thanks. But this is the manual way that I am aware of. Setting it this way would be too tedious for hundreds of symbols. And this procedure has to be repeated every week, because these tickers are weekly options. I am looking for an easier way, if any, through some keyword used in import ascii format file OR any command/procedure in AFL.
