Im doing minimal scalping by selling otm calls on expiry day.
Eventually, the 20Rs charged by Zerodha per F&O order , is significantly reducing the margin.
OTM call contract (if bought) expires worthless, if i’m a call option buyer. for seller?
Currently i buyback at 0.10 or 0.20 levels.
But what if i dont buy back, and the OTM contract expires?
I wanted to confirm here , before experimenting.
As shown below, the buyback order increases charges.
@labtrader if you’re the seller and the option expires worthless, then you retain the entire premium. If for some reason the option goes in the money then it will be a loss for the seller and the difference amount need to settled.
Beware, don’t do this in stock options because there you will need to deliver/accept stocks in case the option expires in the money and yoture the seller.
No brokerage if position is expired at OTM. You can read more about it here: What happens if the option contract is not squared off on the expiry date?
Then you will save on the square off brokerage… So yes you can go ahead an experiment but only do it in Index Options…
thank you, exactly what i was looking for.
thank you., so far wasting in charges on few redundant square-off s
