I go long when the retracement of the previous extension hits 61.8% level. I expect a recuperation from 658.68$ to 683.38$. That last value is the Fibonacci extension of the hypothetical retracement. I can see that there is a little bounce at 38.2% but I think that this will be the B of an Eliot wave.
I don't think that 713$ will be reached again today.
