Aren't those information private? And switching to time mode should be able to tell you how much is bought/sold on what time. Institutional investors hold large sums, but I doubt that they're that silly to dump on the market.

Brokerage is only charged when a transaction takes place. And at the end of each trading day, you'll receive an email with the breakdown of the fees charged (stamp duty, brokerage and clearing fee)
