Quarterly settlement issue

In the link you shared, it says 50% is retained in cash, and not collateral.

Also, this query was raised in an earlier thread, where a reply by another Zerodha member is along the same lines as the two scenarios I raised earlier…

Maybe I haven’t understood what you have written here, but even this is incorrect. Cash is only required only for MTM, brokerage, charges etc., rest if cash collateral > non cash collateral, there’s no need to have cash > collateral.
