IB + put options, seek expert calculation

[jasonlim1988]

Suppose I have 100k USD cash.
The A share price now is 110/share, I short 10 units of put options with , strike price 100.
Price hit 100,Im assigned with 1000 units of A share and my cash is now 0.

My balance now is net liquid 100k ,no cash,no leverage.

Now with IB overnight leverage limit of 1:2.

How should i calculate how much further puts I can short?

If your account is reg t margin, you can short 20 PUTs and if the strike price is hit, your portfolio will be 2X margin utilisation.

ok..thanks thanks.

it's always net liquidation value : total asset (cash purchase + loan purchase). 1:2 for overnight right.
