Here's one for you rookies out there to learn from. I put in to purchase some Rivian stock at the IPO just above what they were speculating it would open at. Apparently it flew by the price too quickly for my sale to be executed. I was bummed, then forgot about it. Apparently I needed to cancel it based on the way/type of request I made, but didn't. So like a week or two later I get a notification that my sale executed... as it was in free fall. Total kick to the nuts, by the next day it was so low that it wasn't even worth trying to sell it.
