Below is an extraction from the members discussion re the Globex Sentiment Index and potential divergence (mentioned by Darryl) and why that was not the best data point in this situation but where buyer efficiency was key. This subject and analysis often also accompanies changes in trend.

Similarly, if there is a high degree of seller inefficiency on a decline - the inverse condition, that would also be a bullish backdrop and suggest a bear-trap. This example is not shown here.
