Depends on the situation, I close out each side (leg) at a time. I even enter multi leg trades one leg at a time. But that's a whole different thread.Are you sure you want to do that? Once you close one side, your risk is no longer bounded? But what do I know, I only trade directional. Perhaps some other experts can educate me too.
I just closed out short side of AAPL spread and left the long side alone, it was down to 0.
