Why is my Stop Loss changing from the Combo to the Short Leg?

This happens because the Long Leg has fallen below $0.10, and there's a risk that stopping out of the Combo will no longer be possible. The reason is that in case of a Combo Stop, you might no longer be able to sell the Long within the Combo. To prevent this situation, OptionsApp ensures that Long Legs that have become very cheap are no longer stopped out and are thus ignored. As soon as the Long's price rises back to $0.10 or above, it will switch back to Combo Stop.

From version 2.0 on, this behavior requires an approval in the user portal. Details: Rebuilding of close orders when a leg becomes untradeable.
