Vertical spread question

[carlaherrera]

The choice of the strike must be based on your spread. Do some research and market analysis and you will come to know what works better.

What I meant you can see in this pic. It shows 49/49.5 and 49.5/50. I know I can choose what I want but if instead of choosing 49/49.5 or 49.5/50, I do a 49/50, would that make it harder to sell since it’s not a standard option listed?

you have your option chain displaying vertical prices across the strikes. The “pair” is just the default way TOS displays it, but you can choose any type of spread you want, no “standard”
