Secondary Test (ST)

A revisit of a candidate climax area: spread, volume and price response are compared with the earlier event to assess whether pressure has diminished.

In plain terms — Price returns toward the climax area to test the balance between supply and demand. A revisit on lower volume and narrower bars is consistent with diminished prior pressure, but does not guarantee it.

Definition

A Secondary Test (ST) revisits the area of the Selling Climax in accumulation or the Buying Climax in distribution. The analyst compares the test with the climax: activity, bar spread, price progress and the quality of the following response.

In an accumulation schematic, a favourable test tends to show less selling, narrower spread and lower volume as price approaches SC support. In distribution, the mirror reading looks for reduced demand near BC resistance. For this entry, the comparison remains contextual and is not converted into an automatic percentage threshold.

The ST compares the new visit to support with the SC; phase A can contain more than one test.
Element Evidence consistent with a successful test Evidence requiring caution
Volume Lower than at the climax Persistent or increasing
Spread Narrower near the area Wide in the direction of the prior trend
Price Holds or recovers the area Decisive progress beyond the climax extreme
Follow-through Response in the opposite direction No response or contrary acceleration

Not a binary verdict

Wyckoff literature allows for multiple STs after an SC and further tests during phase B. A slight move below the SC low does not automatically invalidate the structure; a new low with forceful selling does, however, increase the prospect of further lows or prolonged consolidation. Even an apparently successful test can be negated by later action.

Teaching example — A candidate SC appears at 36.5, the AR reaches 42 and price returns to 37.1 on markedly lower volume and narrower bars. An ST reading is plausible. Before treating the range as established, the analyst still observes the response and retains bearish continuation as an alternative.

Common errors

  • Calling every pullback inside congestion an ST.
  • Declaring phase A complete from a single volume comparison.
  • Requiring every test to stay above the SC or below the BC.
  • Turning a descriptive label into an automatic entry rule.
