Me thinks it was a very fat finger.
Me thinks this all is a BS statement from OP... maybe if I read it backwards as his nickname suggeste it might make sense

What?

It's actually considered market manipulation, yes. And the exchange can bust the trade, even some time after it was made.Thanks McGinnis, So the market does not allow for buys ever to be well above the market? I guess there are programs to stop this from happening to not allow market manipulation.... OR Fat Finger Idiots like me? ( I ended up making a fair amount of money that day, which was hilarious in hindsight)
Guys, I used 6k and 9k as examples to simplify the original post. I don't paper trade. I trade much larger than you think across 11 markets.
It was a mistake that I have never made and I wanted to run it by you guys.
OP was an honest question.
Monday was awesome for me, bought NQ's front month, 6803, sold 6830, then shorted 6849, and covered 6825. Very very very profitable day. (my 6803 was 9803 Limit buy, that's the error I made flipped the 6 and 9 half asleep on a Monday morning)
I'm so insulted you think I'm a paper trader hahahaha![]()
