AGQ: bought today

I bought the ETF Pro Shares Ultra Silver (NYSEARCA:AGQ) today at market open at USD 59.25

This purchase was made by mistake. I thought I had given an order to sell at market open and then cancelled that order a minute or two before the open but it seems that I gave by mistake that order to buy and it did not get cancelled fast enough before the open. Too bad; I am holding on to these additional shares for the moment and see if I can sell them soon at a profit.
