institutional volume

[murray t turtle]

I know this varies a LOT depending on the security but can anyone take a guess at what percent of volume of the index of your choice is institutional? Same question for block trades.

Anyone know of a site or software that will sms me if institutional volume or block trades suddenly drop?

IBD {Investors Business Daily Newspaper} has published that sort of stuff.[2] Volume is secondary @ best;200 period moving average, on volume may help?? If it helps once a year that is still help. TA is the study of price + volume+ that is the order, price + volume.
