There's a new article on Investopedia by FXCM strategist, Boris Schlossberg on scaling up a trade.  Scaling up a trade is to add to a position ONLY after it becomes profitable.  Most traders may be familiar with the scale down trade which is adding to a losing trade.  Richard Dennis, a very famous pit trader stated that scale up trades are only successful 5% of the time.  This technique seems like it is for more risk tolerant traders and not for me.  With great risk sometimes comes great reward though.
