Quarterly settlement prevention

@ShubhS9 @siva

Last time i got the quarterly settlement email was back in December 2020 and I got that mail again yesterday stating

Next quarterly settlement between 2021-12-04 & 2021-12-11.

I have an December 30 expiry NRML options trade currently open.

Am i correct in understanding that if i have an overnight open position during the time frame then my funds wont be withdrawn?

If not then how can i time purchase of liquid bees overnight to avoid withdrawal?
