Wyckoff Theory

Definition
A historical chart-analysis framework that groups price action into labels such as accumulation, markup, distribution, and markdown. These labels are interpretations of a selected chart, not proof of participant identity, intent, or a future move.

Supports: CFTC explains that historical-data trading systems cannot guarantee profits, supporting the distinction between a chart classification and a verified trade outcome.

Key Takeaways
1
Wyckoff phase names are chart interpretations, not standardised measures or verified descriptions of market participants.
2
Declare the range, data, timeframe, phase criteria, and invalidation rule before measuring an outcome.
3
A range or spring pattern cannot prove institutional intent, retail behaviour, manipulation, or a future price path.
4
Test any complete rule out of sample with realistic execution and losses; phase labels are not a trade instruction.
Practical Example
A researcher defines a daily range and a spring rule before the next month of data, then records every occurrence with the same price and volume source. They compare the rule with a benchmark after including trading costs and failures. A later rally may be recorded, but it does not prove who traded, why the range ended, or that the next labelled range will produce the same result.

Liquidity GrabAn informal retrospective label for price crossing an apparent chart level and then reversing. A chart alone cannot prove stop-loss concentration, intent, identity, coordination, or an institutional order behind the move.

Power of 3 (PO3)An informal three-part narrative sometimes applied to a selected price range, a move beyond it, and a later move in another direction. It is not a standard market-cycle model or evidence of manipulation, intended direction, or a trade setup.
