That is pretty much exactly the set up I use - yeah, thats my thang. I find it very profitable, if you have a good trading structure around it.
I would have done pretty much the same thing as you - with the exception that once it returned through that range downward I would have entered again with a short.
What I love about the set up is you can try two or three times with small losses to catch it but once you get the direction it more than compensates. And every then and again you hit a home run, while on other occasions you may settle for small losses/gains, or (in my case) mostly b/e.
I wonder if the duration of the range matters, I think it might.
