Friday 11/3/17 is the US monthly payroll report also a Full Moon day.
The SPX Elliott wave pattern from the bottom made on 8/21/17 looks very much like an impulse wave. The pattern from 10/23/17 appears to be in a series of four's and five's - the final fifth wave up could be complete in the first two hours of trading on 11/3/17.
If a top is made on 11/3/17 there is a high probability that this could be at least an intermediate peak leading to a multi month correction of 12 - 17 %.
