I am looking to trade in shorting options looking at the theta decay angle.For example the stock CMP is 2000 and i feel it will not go above 2300 so i would like to short this call while going long a 2500 call for protection(Credit spread).But I have seen that one gap up or wrong trade takes away all the gains plus more.Is there any way else to hedge or prevent this loss?How do experienced traders deal in this type of trade as even many times the stop loss will also not get triggered at any favorable rate.
