Just curious if anyone might have an idea on the composition of daily market participants. I've heard different numbers from different sources; be it individual traders, trading desks, funds, etc. Would appreciate any info anyone might have regarding NYSE and Nasdaq daily activity.
I'm not sure, i'm not sure if you can get a clear number, but I know that the NYSE breaks out program trading on a weekly basis. It is usually between 30 and 45% on a weekly basis.
