I also traded a lot of NYSE odd lots, you know, back when GLW was $300 a share. I never consciously tried to buy bid or sell ask, had now idea there was a rule, etc. I got some emails from IB about the issue, and then tried to get a wire out of my account and they held it up saying there was an investigation in progress and some specialists were going to come after me for damages. Whoa, like I probably might have been on the hook for some pocket change, and they were holding up my paycheck! To IB's credit, it only took one email from me to get the money flowing again, but sheesh. Then, I never heard another word about it.
