ES S&P futures testing 61.8% fib from drop line in the sand

Today the S&P futures are teasing the 61.8% fib, some call the line in the sand. This would potentially signal a further correction coming or an "all clear" for higher prices on the indices. Today may be important, but with OPEX or options expiration it may mean little. Next week will be the real deciding factor with May ending and the sell in May attitude could take over.
