Database- and Screeners via script

Hello - I'm running about 30 screeners via script.

Right now, I have them looping one at a time. each one can take up to 1-2min. Depending.

If I split the work into 6 scripts(5 screeners in each) and execute them at the same time via task mamager. Would their be any problems with the integrity of the data/database? I.e. several screeners overlap in the symbols list and multiple scripts would be accessing quotes data for the same symbols at the same time. Any issues or potential for erroneous data?

Hi,

There won't be any problem with integrity of the data. We have internal mechanisms that prevent reading or writing the database at the same time.

However, it is always a good idea to make a copy of your database (for other reasons).
