Nine Buying/selling Tests

Nine Buying/selling Tests turns the Wyckoff tradition's pre-entry gate into a live, scored checklist. The build anchors a trading range at the scan window's extreme, measures the trend into it, and grades the nine buying and selling tests continuously, each row showing reading, pass/fail state and exact rule, the score in the header. The range box, stride line and projected objective are drawn on the chart.

How to Trade the Nine Buying/selling Tests?

  • Score accumulating: the checklist is convergent evidence, not a trigger — the Wyckoff family tradition asks for most or all tests before committing; threshold and 9/9 alerts mark both stages.
  • Auto side selection: a window that fell from its high into its low is audited as accumulation, the mirror as distribution; Test Set can force either side.
  • Stride break + stepping structure: a dedicated alert marks this pairing some practitioners use to stage a starter position early.

Nine Buying/selling Tests Settings

  • Test Set (default Auto), Scan Lookback (Bars) (default 250), Swing Length (default 5) and ATR Length (default 14): the audit window and its pivots.
  • Minimum Prior Trend (xATR) (default 3.0) and Extreme Hold (Bars) (default 10): the fulfilled-objective test.
  • Climax Volume Multiple (default 2.0), Volume Average Length (default 20), Secondary Test Volume Ratio (default 0.75) and Secondary Test Proximity (xATR) (default 1.5): test 2.
  • Activity Ratio (default 1.1), Benchmark (default SP:SPX) and Relative Strength Length (default 50): tests 3 and 7.
  • Minimum Cause (Bars) (default 40), Objective (x Range Height) (default 1.0), Minimum Reward/Risk (default 3.0) and Score Alert Threshold (default 7): cause and payoff.
  • Checklist position/size, plus Range Box, Stride Line, Objective Level (on) and Climax / Test Markers (off).

Frequently Asked Questions

How does this relate to Accumulation vs Distribution Ranges?

Accumulation vs Distribution Ranges classifies which side is likely operating inside a consolidation; the nine tests ask the later question — is the range finished and worth trading — as a formal readiness gate.

Why does test 8 use duration instead of a point & figure count?

The traditional measure is a point & figure count — its own tool. Bars since the anchor stand in as the proxy; Minimum Cause sets how old a base or crown must be.

Does the checklist work without volume data?

Partially. Tests 2 and 3 are volume evidence and cannot pass without it; the other seven grade normally, so the ceiling on volume-less symbols is 7/9.
