UCO is a very popular etf and I saw IB had a tons to offer for shorting and my annual interest rate was only 2.x%
I had double checked and never recieved any warning email from IB before.I just received this email right after US market closed and I am on my way to work do cannot login IB account to check what is going on.
Luckily this is only very small amount of money. The email doesnt say what price had been executed at all.
UCO is one of the most popular etf and I monitor a lot of etf…
