Trade busted (reversed) after 3 days. I cant understand

ECN - BATS
nasdaq stock

Is the limit only 30 minutes ?

 

Not 30 min. I busted a few times at the end of day, but your was busted after 3 days, which is rare.

 

Which brokers did you use? How bad was the damage? And did the broker come up with a solution?

 

ib. No much damage. No solution, only leaving me with an open opposite position overnight.

 

Which stock? Amount?
Sounds like you were executed at an erroneous price.

There are no free lunches here.

 

Is it possible the bust occurred earlier and your broker delayed telling you about it or you noticed it later?
