FWIW, I'm more comfortable now with 1366 SPX as a possible low than 1375 SPX. The reason is the fibs off 1576 work better with 1366. Today's high is the .382 re-trace area, the 1490 area is close to the .618 re-trace zone, and 1471, another pivot area, is the 50% re-trace off 1576.
Often times we pivot at what are later major fib levels.
Watch the VIX, watch the weekly Put/call on the CBOE hitting 1.45 on a daily close.
