Usd/Jpy: Nothing Goes Straight Up or Down

The Usd/Jpy is pulling back pretty strongly this morning...don't know why but then again I don't usually ask why, just try to trade the chart patterns. The pair has been trending up for a while within a good channel, here's an hourly chart with a linear regression trend channel that shows the current uptrend.As you can see, the pair has been steadily trending for some time now. Does this break signify the beginning of a trend change? I don't know...my gut says no but I'm biased because I'm long the pair. Nothing goes straight up or down (or at least it is a rare occurence) and a good pullback is probably long overdue. I added a little to my position this morning and am sticking with the "buy the dip" plan until I'm proven wrong. I'll know I'm wrong when my stops are hit (still a couple of hundred pips away from that) or when my system registers a sell signal on the daily chart...sell signal will probably register if the pair closes below 96.70 level. Since neither of those conditions have occured, I'm adding.

Good luck out there.
