Tried to trade credit spreads, failed miserably ($6.5M margin call)

Sniped these for $0.01, expecting NVDA to continue its rise and be able to profit on the IV making the spread between legs (haha) bigger. The gain is a facade.

I have NO IDEA why I got exercised. But now I’ll take max loss at open, and I’ll owe interest on $7.2M overnight.
