Broker flow
Daily buying and selling by each broker in each stock, split into foreign, local and government investors.
Sources
The exchange's daily broker summary for the regular board.
Coverage
Daily from Jan 2, 2023. Over the last 30 days it covered 752 stocks a day on average (between 529 and 830) and 89 brokers.
Update frequency
Once a day, after the close.
What an agent can do alone
Nothing without an account: broker flow is paid data.
Known gaps
Summing net buying across every broker in a stock always comes to about zero, because every trade has a buyer and a seller. Net flow means something only per broker or per investor group, such as foreign net.
When it fails
A day that has not settled yet is shown as missing, not as no activity.
