Plots like these from this week's FED financial stability report (https://www.federalreserve.gov/publications/files/financial-stability-report-20220509.pdf) are nice. They quote the margin requirement from the exchanges. Does anyone know how to get similar data from brokers, like IBKR? other than recording them by oneself. I called IBKR customer support but they don't offer any help. Thanks.

Sorry I should have been more clear. What I want is the margin charged by broker, not the one from CME/ICE, since brokers tend to charge extra margin on top.
