Just call your broker and tell him/her you were "force converted" and brainwashed. It's not a legal trade, because you lacked the mental ability necessary for trading.
Or call the shareholder abuse hotline.
If you have any problems, just post your broker's name and number here.
I call my broker and get these trades undone all the time - I've never had a losing trade. Just last week when things went south, I called and told him my computer traded by itself and the broker undid it. Really ... not a problem at all.
Or just tell your broker you put in the wrong ticker symbol. You wanted to buy MNRKP, because you just saw it was listed as trading in the Monarch Press Release; but you got stuck with MNRK.
