In plain terms — After a candidate climax, the dominant pressure subsides and price moves the other way. The extreme of that move helps draw the first opposite edge of the trading range.
Two meanings of one abbreviation
In an accumulation schematic, the Automatic Rally is the advance that may follow a Selling Climax. Wyckoff teaching attributes it to sharply reduced selling pressure, demand and short covering. The AR high helps define the provisional upper boundary of the range.
In a distribution schematic, the Automatic Reaction is the decline that may follow a Buying Climax. Its low helps define the provisional lower boundary. “Automatic” describes the response as climax pressure subsides. To avoid a mechanical reading, this entry assigns neither a fixed threshold nor a certain or immediate outcome to the move.
| Context | Prior event | Move | Extreme used as reference |
|---|---|---|---|
| Accumulation | Candidate SC | Automatic Rally | AR high, possible resistance |
| Distribution | Candidate BC | Automatic Reaction | Reaction low, possible support |
How it is assessed
An AR gains meaning from context and follow-through, not from a preset percentage rise or volume level. A broad rally after intense selling is consistent with changed price behaviour, but it does not prove a reversal. The later Secondary Test examines whether the climax area is revisited with less pressure.
Teaching example — After a possible SC at 36.5, price rebounds to 42. The high at 42 becomes a provisional reference, not certain resistance. A later return toward 36.5–37 on smaller spread and volume strengthens the SC–AR–ST reading; another forceful decline weakens it.
Reading errors
- Calling every bounce after a decline an AR without a candidate climax and later structure.
- Treating the AR as a stand-alone entry signal; its main role in the sequence is to help delineate the range.
- Assuming that AR and ST set exact, immutable boundaries; they identify reference areas.
- Confusing a retrospective description with a certain forecast.
