Follow through or reversal?

Following the fake out in the beginning of July, last week TrendXplorer issued its third buy signal in six months time for SPX. Until now none of those signals actually got triggered, they were reversed instead. Notice how price is hugging the 200MA. Furthermore the DJIA even had seven buy signals, all above the 200MA, but none with any follow through. Will this time be different? We just have to wait and see.
