When you know that the trade is no good it is best to get out ASAP, do not hesitate or delay or try to think It through just close the trade.  It has been said that it is never a loser until you get out.  It will come back.  Once these phrases are stated, it is an affirmation that the trader realizes that the trade is no good, it is not coming back and it is time to exit.
