S&P Data Files are too big compared to other symbols

Dear SC team,

I noticed during developing some ACSIL algorithms that when I run tests under DAX (symbol FDAX) the time it takes me to complete a replay (back-test) of 1 year is almost half the time I need to complete the same test for S&P (Symbol ES). I also noticed that the data files stored in my computer for DAX are 150MB size in average, while for S&P the size of the data files is at least 10 times bigger, around 1.5GB. So I am guessing that I have somewhere in SC a box ticked for S&P to save DOM data or something similar. I have looked everywhere but found nothing.

Does it make sense what I am saying? Can you think of another reason why would it take me almost twice the time to run a test on S&P compared to DAX?

Thanks!
Ernesto

That file size is correct based upon the market activity for that symbol. It occupies much less space due to compression that is used.

But make sure you are running a current version of Sierra Chart to ensure that the compression is actually being used.
