About 7% on average I believe but I can't know about on non average days, like the past ones have been.

I know a lot of people who logged in to their accounts last Monday who never normally to sell shares and hold cash until the market bottoms. I'm guessing the retail volume in the past week has been higher than ever.

Even barring retail investors telling brokers to sell shares, there are all sorts of reasons consumer behavior can force share sales including increased expectation of withdrawals by banks, people not contributing as much to 401k. Defined allocation mutual funds rebalancing, etc. Also, today a lot of low cost brokerages sell trades to algotraders for fulfillment, so an order for the sale of 1 share of a consumer investor can end up accounting for more in trading volume
