If you already have an open position, in this case you bought a call option. So u will book profits by selling it. Sell = square off here and not shorting/ writing it.
Calculation of profits/ loss simple. You will get the price at which it is trading
Suppose u have bought 8600 CE at 30 Rs while Nifty CMP is 8500.
If tomo Nifty @ 8600 and ur Call option has value of Rs 50, Ur Profit = 50 - 30 = 20 Rs
If u keep till expiry, this call option will lose time value and if Nifty expirs at 8600, u get 0 (as it expires worthless).
If Nifty expires 8700. 8600 CE value will be 100. Ur Profit, = 100 - 30 = 70
in addition to above answers, while squaring off your positions place your orders using the same product type (i.e.NRML/MIS)…if you have bought option using MIS product you should place a sell order using MIS product only then only it will get squared off. if you use different product type for both buy and sell orders you will be creating two different positions…so be careful while you place an order to square off your position…
Thanks Charles for the answer with an example.
Now does it work the same way, irrespective of the fact that when i bought the call option it can be OTM ,ITM or ATM. As i new to this i felt ATM or ITM are better to start with.
Thanks a lot ShreyaDR.
I found something very useful in these cases studies.
But i see that in first example the Put trade is squared off even before the Strike price reached.
Is this valid? IS SQUARING OFF allowed even before option reaches Strike Price?
Now the doubt is have is does Square off means i am actually selling this BUY options right to some one else and the option not getting closed completely like on expiry day?
Sorry for basic questions but some are just out of my thinking and i dont get the answers in the theory.
