volume confirming double bottom on usd?

Still to early to definatively be called a double bottom as price still needs to exceed the intervening peak, but the volume on UUP (Bullish USD ETF) is strongly suggestive that this may be the case. There is a volume peak coinciding with the first low, followed by lower volume on the rise to the intervening peak. This is followed again by heaving volume on the second low.



Not quite sure what the meaning of this is, but its also worth noting that while the USD made a very slightly lower low, the Euro did not make a slightly higher high......
Am open to any thoughts on that one.
