Hi guys, I have just began learning about vertical spreads, and have done a little paper trading with them. I am wondering though if I trade something like 100 vertical call spreads(buy 100, sell 100) and I am looking to just hold them for a day, do I have to be worried if there is very little relative open interest in the options (i.e. 1,000 open interest on each strike)? If I understand options correctly wouldn't I be holding 10% of the strike options in the market and wouldn't it be hard to unload them, or I am not understanding this correctly. Thanks alot for any help you can provide.
