Who this entry is for — Anyone who needs to draw the edges of the range. After the climax, the market «bounces» or «reacts» automatically — and that move fixes resistance (accumulation) or support (distribution) of the trading range.
Source: Wyckoff Schematics (Pruden, MTA 2006); Robert Evans (SMI) — the AR ceiling in accumulation becomes the reference for creek and JAC. In distribution the tradition often uses «Automatic Reaction» for the post-BC decline.
Prerequisites
Selling Climax or Buying Climax — the AR always follows a phase A climax — and Trading range.
Definition
In plain terms — After panic (SC) the stock bounces on its own because selling stops — that is the Automatic Rally and marks the initial ceiling of the range. After euphoria (BC) it falls on its own because buyers exhaust — that is the Automatic Reaction and marks the initial floor of the distribution range.
The Automatic Rally (AR) in accumulation is the bounce that follows the SC: short covering, institutional demand and absence of new supply push price up and define the upper resistance of the provisional range. In distribution, the Automatic Reaction (same AR abbreviation in Wyckoff teaching) is the post-BC decline that fixes the lower support of the distribution range. In both cases the move is «automatic» because it does not come from a new trend campaign — it is the mechanics of climax exhaustion bringing price back toward equilibrium.
| AR in accumulation | AR (reaction) in distribution | |
|---|---|---|
| Follows | SC | BC |
| Direction | Rally | Decline |
| Defines | Range resistance | Range support |
| Volume | Often moderate-high | Often moderate-high |
| Then | ST toward SC | ST toward BC |
Accumulation example — SC at €36.50; AR in five sessions brings price to €42 with declining volume on the last bars. The provisional range €36.50–€42 holds until the ST tests €36.50–€37 at volume −60% vs SC.
AR, creek and change of character
The AR in accumulation is not just a number on the chart: it is the first visible change of character to the public — the stock rises faster than the downtrend had conditioned. Later internal highs in phase B trace the creek (Evans); SOS/JAC breaks it in phase D. In distribution, losing the AR support in phase D with a SOW confirms that supply has regained control.
Common mistake — Confusing the AR with a long entry signal (or a short on the distribution AR). The AR defines the range — phase A is not complete until the ST confirms the climax. Operate in phase C–D, not on the AR.
