Dax Future weekly analysis

This is weekly analisys of Dax future using Bollinger Bands (20,2), volumes and Bollinger BandWidth.

This chart shows that weekly prices are touching the upper band with decreasing volumes; this suggest to me that the up trend started at the beginning of march is weaker.

Have a look to the Bollinger BandWidth: flat!

Is Dax entering in a new trading range? If this analisys is well done and you are a long term investor, well... don't be in a hurry!
