You could put a 20 ema on it and trail it with the 20 ema until it takes you out.
Same thing works using the mean of the Bollenger bands.
That way you can let it run as far as you can and maximize the profit.
.....or to wait for some kind of trailing stop to gets hit thus giving up the pips lost by the trail.....
......the eternal problem for the profitable trader 
He's an idea that I use......I prefer to use fixed bands for my envelope - based on research for each time frame - and look to make a partial exit when the band is hit. A confluence with a supply area / pivot / fib expansion will help confirm the probability of a pull back as will a candlestick pattern especially if with higher volume....obviously both are first noticed on a lower TF.
Whilst I see the hammer at yesterdays new low into a supply area, I dont like the low volume and small range, so I await further confirmation before considering a postion long - as opposed to an intra-day long
Meanwhile, a Happy and very Prosperous New Year to all
Trading Levels with WRBs
and that at that level price would be extended at the lower daily band. In the thin trading conditions good swings testing S&R areas could be expected and intra day timing showed 1200 gmt to be linked with 2 prior lows - ok, that's a bit esoteric - but it alerted me take notice around 1200 GMT - and its always good to watch the close of the hourly candle.
