Of course this is all just my own opinion, and I have no proof that there was government intervention when it hit 56.5 last time, but it sure would make complete sense if it did. I was extremely surprised that it stopped at 56.5 because there probably isn't very much "natural" resistance between that and 50.
As far as resistance (support) is concerned, there was a major fib convergence @ 57,60. Also, mind the unfilled gap near 56 area:
