There is a very nice case of the Volume accumulation setup on the USD/CHF.
The downtrend tells us that the volumes accumulated in the rotation were most likely volumes of strong sellers. When the price makes it back to this level, those sellers will try and defend their selling positions by aggressive selling activity. This should push the price lower again.
*You can also notice how nicely the price reacted on the volume cluster created within the trend (Trend setup).
