Adding to a Winner; Chess Moves

I added more to my UNP short position, marking it up to a 6% portfolio position now. I added to the short, just now, at  $113.72 after my original entry at $118.73 in this blog post. Rails continue to get hit. And the UNP hourly chart, below, is flashing signs of breaking down below a bear pennant pattern (highlighted). I am keeping my cover-stop at $124 for now. As a famous trader one said: "Losers average losers; Winner average winners." I am playing for the UNP short to become a bigger winner for me.
