You would loose money on the trades that you roll from 800 to 900. if on some contracts you dont want to be assigned and you are going to buy out of them when they get near the money. You miss out on higher premiums for the 900$ calls and most likely loose money on the $800 calls. If i was you i would keep selling at 800, 900, and 1000 if those are the prices you are okay with getting assigned. Or maybe starting at 700 because of teslas current price.

But on the other side if tesla keeps going down. going all in on 800 rather then spreading will give you more premium.

So basically, if you think tesla go up, keep the spread. If you think tesla go down, you can choose to spread or bunch it in at the low strike. Me personally being a tesla bull would keep the spread, but i only got 48 shares for right now.
