trading volume / value - Institutional v/s retail on exchanges versus, amount, example, between, volume

Hi,

I was looking for breakup between institutional versus retail in terms of amount (value or volume) of trading done on world exchanges.

For example, in MSCI ACWI - what % trading can be attributed to institutional investors versus retail investors?

Any leads, data sources anyone?

Thanks in advance for your help!!

i think retail is 1/3 of volume
