Where can I find data on cash sitting in brokerage accounts?

Looking for a site that tracks cash/cash equivs sitting in brokerage accounts.

 

Would love to see this data from the private brokers but very highly doubt will ever get an unbiased view.

IMHO CFTC, FINRA should require all reg brokerage firms to disclose.

 

yes thats right, NFA, FINRA, SIPC, CFTC...wow almost I forgot our dear SEC. thats gonna be enough.

 

www.finra.org
www.nfa.org
www.sec.gov
www.cftc.gov

check that out.

 

CFTC has the FCM capital and customer cash data at the end of every month.
