Do you have an exit strategy? Never open a trade without one.
At what level of loss will you accept your original decision was wrong and get out?

I ask because the 1 hour chart is quite interesting.
I can see the logic of shorting it now, because it is currently again attempting to break through the 238/240 previous highs and should it not be third time lucky and fail again, then it would be likely to test support around 225.
But you are talking about selling at a level just above resistance, after it has broken through: not a good idea.
