The example you show is of an entry within a very defined range on the GBPJPY (234.55 - 228.20).
In the example you posted I’d usually wait for a little further confirmation before firing an entry off.
But that’s just my view according to the usual parameters I adopt for trading that type of environment.
If I was tackling that particular pair, looking to trade the well developed range it’s currently displaying, then I’d have preferred to execute nearer the extreme boundaries.
That’s not to say your entry was either dangerous or ill-prepared, simply that it wouldn’t have been of interest to me.
As long as the trade fits your criteria for that particular event (a range set up) & you can locate an appropriate protective (stop-loss) zone, then you’re good to go.
I’ve included a chart highlighting where I’d have been looking for an entry if my arm had been twisted to get aboard 
But as I say - that zone wouldn’t normally tempt me at all.
