Most of the posts here totally misunderstand things. There is no such thing as a "losing position" - once the market has moved against you, you have already lost the money. Your intial entry is a "lost" position, and the money has already gone. You are now in an identical situation to someone who has just entered the market and is currently at even.
The vast majority of bad trading errors after entry occur because people think in terms of where they entered. You should completely forget where you entered, and only judge your exit or adding decisions on the current market situation. All your trading decisions should be based on what you would do if you were currently flat. Forget your current position, just analyse the market as if you were flat, then if you would get long 5 lots here, then you should be long 5 lots, regardless of whether you are currently flat, long 10 lots on a huge profit, or long 20 lots on a massive loss, or short or whatever.
Until you understand that your entry price and current position size has nothing whatsoever to do with what position you should have on right now, you will never really understand trading. Comments like "losers average losers", "never add to a loser", "add to a winner" etc are just so much cliched garbage.
