Quote from FX_Cowboy:
While I pretty much nailed the top of the EURUSD uptrend (in truth, I thought it would go just a bit higher, so I still had some powder dry in case it got up to around 12315), I completely screwed the pooch by allowing myself to be shaken out of my short position way too early.
In retrospect, it would have been much wiser to keep at least 1/3 of my position at B/E, and let the winner run (as Buk demonstrated last week). Ah well, live and learn... On the brighter side, I made some money, so I'm still a happy camper, and hopefully a wiser one.
But it was a good call. Why don't you use trailing stops?
