I'm wondering if someone can help me figure out what I did wrong. I bought an ITM call option for a year from now (leap) on Robinhood. However, when I go to sell an OTM shorter term call option it says that I don't have enough shares for the collateral needed to place the order. I thought that the leap option was a synthetic way of "owning" the shares and that the system would automatically allow me to use it as collateral. I've watched YouTube videos of people doing exactly this on Robinhood and they do not receive the notification. Anyone know what I am doing wrong? Thank you and please be kind - I'm new to this!!
