Good observation Terry. I have also noticed this occurring with ECU for a couple of years now and that explains why the Accumulation/Distribution Line has been in a gradual ascent over the same time period. This is because it calculates the value based on the location of the close relative to the range that day. Those last minute "pops" at the end of the day help keep the line moving higher.

It's extremely frustrating to see the stock you own move opposite to the underlying commodity prices and its peers.
