Hi DT,
I had an earlier thread that was moved to another section. Anyhow, it had a question about volume that perhaps you can answer. In the US, volume executed in ATS such as dark pools are required to be reported to the Trade Reporting Facility (TRF) within 90 seconds. I have seen estimates of total dark pool volume being somewhere around 10-15% of the total market volume. But on most days, TRF volume is around 30%. So where are the remaining ATS trades coming from?
I'm just an ordinary retail trader trying to absorb all the knowledge and it would really be useful to know where that liquidity is.
Thanks for your help.
PS.: I also had a second question that dealt with different market makers in the US - Citadel, ATD, UBS. Do you know anyone on this forum who may be able to help me with the details? Someone with extensive experience scalping or doing high frequency trading perhaps.
