Divergence

A disagreement between corresponding price and indicator extremes, such as a higher price high with lower RSI. Identification depends on parameters and swing rules, including confirmation timing. Divergence describes the data; it guarantees neither weakening in every measure of momentum nor a reversal. Additional confirmation is a rule to evaluate.
Example. Price has confirmed highs at 1.1000 and 1.1050, while RSI at the corresponding points reads 72 and 68. This is classical bearish divergence under that rule. If a swing requires two later bars, identification occurs after those bars close, not at the high itself.

Compare corresponding points

Record whether the comparison uses closes, wicks, local indicator extremes or indicator values at price swings. Specify minimum separation and ties. Changing point selection can create or remove divergence without changing the market history. Price and indicator points should not be selectively paired because they produce a convincing picture.

Classical and hidden forms

Classical bullish divergence combines a lower price low with a higher oscillator low; bearish divergence combines a higher price high with a lower reading. Hidden bullish divergence commonly pairs a higher price low with a lower indicator low; the bearish version reverses those relations at highs. These are separate labels requiring separate evaluation.

Repeated warnings

Divergence can recur while a trend continues. An oscillator summarises a selected price feature, not every measure of dynamics simultaneously. Price may reverse, slow or continue. A structural confirmation rule adds another condition and may delay entry; it does not guarantee that false events disappear.

FAQ

Does divergence guarantee reversal?
No. It describes disagreement under the specified indicator and point-selection rule.
Why do charts show different divergence labels?
Data, timeframe, oscillator parameters and swing rules can all differ.
