Thanks for this.  What if I sold a call one strike above a call I bought? I am looking at both rise in value. But if I want to sell the call I bought I have to buy back the call I sold (it made higher gains than my call). I get to keep the original premium for the sell but I would take a loss on the buy-to-close transaction. I think I should have done it the opposite way that you described.

That's a debit spread. I think in that case, you'd ideally want the price to go just below the strike you sold your call at for maximum gains (I think that only applies if you're trying to execute the option though). I will admit I'm not as familiar with debit spreads.
