Ahhh gotcha so as long as I’m at 0 I don’t have to worry about that? Damn wish I knew this when I wanted to short Apple today, I was afraid I would end up owing someone 20000 dollars if they exercised the option once I sold my put... now it makes more sense. Never go negative on the amount you own of either calls or puts?

Not if you're a noob, no.
