House Margin
GET
/house-margin
This endpoint returns margin-related information for the specified account. The ratio {house_margin_req / house_equity} is used by the clearing firm to issue margin warnings.
If this ratio exceeds 50%, then 75%, then 90%, you will receive a margin warning (currently this is done over email). At 100%, you will receive a margin call.
The margin requirement value is calculated based on many factors including your margin account type (PM vs Reg-T), the concentration and correlation of your portfolio, whether there are offsetting positons, value-at-risk, etc.
