Thanks for your feedback.
It's indeed strange as I wasn't attempting to close multi-leg options from different exchanges but a covered stock yet my order seems to be rejected in my best interest.
More odd experiences on my call options, even those >30 days out were assigned and I'm made to close them manually, individually incurring more losses than I would with my protective put in place.
Has anyone received Preflight Checks that rejects their orders?
I'm learning from fellow traders here on the restrictive practices of brokers before I slipped into another rabbit hole.
I don't know anything about TastyTrade platform but it's possible they have default settings that you can adjust.
I have accounts at good brokers that have limits you can set to prevent from taking a trade under certain conditions. I'm guessing that's what "preflight checks" is.
