Looks like your purchase price is 2659, the current price is 2655, and the "-830" is the market change from the last close... and has nothing to do with your position. That right, or am I missing something?
GET OUT OF THE MARKET UNTIL YOU CAN DO THIS AUTOMATICALLY. (Or, is this just paper??? PLEASE say it is????) Early this morning (OP was at 0530hrsET), the market was down over 16 ES points. At $50 a point, that's your $800 negative. You Avg. includes commission -- that's why it's got a hanging 5¢. You put up LAST though -- and the last is just down 4pts. -- which would be a $200 loss. If you put MARK, and/or hit Refresh on your screen (or, CTRL-F), your numbers would refresh, and get you away from the -16pts.
