Ok...here is the situation. I was long MCP on friday. I checked the price on my iphone and the price was going down so I decided to sell. I placed a day market order to sell but didnt get any notification that it sold. So i checked my open order status and it said I didnt have any open orders. So about 15 minutes later I went home and placed the same order from my desktop but again, no notice that the order went through and nothing in my open order status. I looked at the price and saw that it wasnt moving and quickly realized that i had placed these orders after the market closed and didnt realize it was a half day of trading. So I just figured these orders couldnt go through because the market was closed. So big surprise when I get up this morning and I now find that I am SHORT MCP as the two day orders I placed went though as soon as market opened even though I had no notice that I had any open orders over the weekend. Had I had any open orders I would've canceled because I dont like to trade the first hour. So MCP goes up nearly $4 per share (about 14%). I call my broker and they bust up the SHORT side of the trade, but not the other day order I had place on friday to sell, so basically i missed that run up because my broker only got rid of half the trade. What should I do? Since all day orders are supposed to be canceled friday at 4pm, what are my options? Should i get my long position back? Do I have to go through the SEC to do it?
