Divergences

A divergence is a disagreement between what price does and what an indicator does at the same extremes.

"At the same" is the operative part. It is not arbitrary points that are compared, but price swing highs and lows against indicator values in exactly those bars. That makes divergence sensitive to how the extremes were found: two tools with different swing settings will report different divergences on the same chart.

A divergence describes something that already happened — momentum weakened relative to the previous leg. It promises no continuation and is not an entry signal.
