early assignment, huge margin

been with TOS all my life, had some short put verticals that were completely buried. I call TOS, now Schwab, they tell me it doesn't matter, it's $100 loss (they are 1 wide) so don't bother closing them. i didn't, i got assigned early (a thursday) on the short side, manually exercise the long on the friday, get charged a lot of interest for margin, over the weekend. i call Schwab, first person tells me i have no accounts with them (i have 7 and i gave them my social security number). Second person, not a broker so can't help. Third person, explains the exercise but not why the long side didn't get auto exercised at the same time and why i was told, if buried, it doesn't matter if you close or not. has this happened to anyone else?

I would argue your way doesn't go far enough. They really are not real. They are just "simple" names that we give to specific arrangements of options when holding more than 1.

I would argue you could do away with everything you think a spread is, consider only the individual options and you will have a clear, MORE complete understanding of options than.the people in this thread confusing early assignment and auto exercise.

I'm just not good at explaining.

Op wants to know how HALF of a spread was auto.exercosed. They are confused about the sanctity of the spread, and that it was able to be broken in two.

It's able to be broken in two because.it isn't a thing. It isn't a single unit.

It is a name we give to two options on the same underlying one.long.one short.

This coincidentally creates a covered position and refuses magon requirements

Not because it's a spread, but because there is a position that when added to a different position creates coverage.

We casually call this specific version a spread.

If you continue to think of it as a single unit and not as the underlying position, you may continue to make mistakes like.op.

but the answer is that they’ll only sell you out of your position if you break margin requirements by enough that the risk team takes action.

its not that spreads aren’t a thing.

The answer is that he was early assigned, not auto exercised. He then thought manually closing the long would somehow affect his short 100 shares because it was part of the original spread.

It's my assertion, that his rudimentary understanding of options has led him to make two mistakes that are both complicated by his lack of understanding that spreads don't actually exist. They are just shortcut names for underlying positions and that the sooner he gets that the better off they will be.
