Well having a look at this time frame the first thing that comes to my mind is that a lower low has been provided.
This might be the first indication that the up trend might be over.
Price has been rising since the 4th of September and might now be on its way to turn bearish.
For that the retracement needs not to provide us with a higher high but yes with a lower high.
If the black line of the DPP holds then I would be very much inclined to take a short trade.
