Point & Figure (P&F)

How to build and read a Point & Figure chart: boxes, X/O columns, reversal threshold, settings, operational uses, and limitations.

On this page

A Point & Figure (P&F) chart tells the story of price movement with columns of X and O. Unlike a candlestick chart, it does not add a new mark merely because time has passed.

Quick definition — It adds an X when price rises far enough and an O when price falls far enough. “Far enough” depends on the box, the chosen price band, and the reversal required to start the opposite column.

The structure at a glance

Thresholds control what appears. Activate the four points to distinguish boxes, continuation, and reversal.

How it is built

The essential procedure is:

  1. choose the price series used by the chart, such as closes or highs and lows;
  2. set the box size, which may be fixed, percentage-based, or dynamically calculated by the platform;
  3. set the number of boxes required for a reversal;
  4. add an X when price reaches the next higher box in an X column, or an O when it reaches the next lower box in an O column;
  5. start the opposite column only when the counter-move satisfies the reversal threshold.

In a simplified example with a one-euro box and a three-box reversal, a two-euro decline during an X column does not yet start an O column; a decline large enough to cover three boxes does. The values one and three explain the mechanism only. They are not recommended settings for every instrument.

P&F does not have a uniform time scale. One column may summarize a few hours or many sessions, while some platforms insert numbers or letters to mark the start of a month. Calling the chart “timeless” therefore means that time does not decide when a new box appears, not that dates and sequence are irrelevant.

How to read it operationally

First check box size, reversal amount, price source, and data period. Two charts of the same instrument can differ when only one of these settings changes.

An X column describes an advance large enough to cross the configured thresholds; an O column describes the reverse. Several columns ending near the same level may make support and resistance areas easier to inspect. A move above a previous X-column high may be classified as a breakout, but it does not guarantee continuation: it still needs context from the trend, risk controls, and the available data.

The chart filters moves smaller than its threshold, but that also hides part of the path. In its classic form it does not show volume inside boxes, preserve individual candle shapes, or reconstruct the intraperiod order of prices by itself.

Control procedure

Before interpreting a pattern, save the settings with the screenshot or journal record. Then compare the P&F reading with the original time-based chart; define in advance what would invalidate the hypothesis; finally, examine results across a series of cases rather than one successful example. A more sensitive configuration creates more columns and reversals, while a broader one filters more. Neither is automatically better.

Technical depth: variants, counts, and limits

Platforms do not necessarily build the same P&F chart. They may use closes or highs/lows, fixed, percentage, or ATR-based scaling, different rounding, and specific rules when both continuation and reversal are possible within one bar. With dynamic scaling, historical output may also change when the volatility parameter changes. A reproducible comparison therefore requires provider, version, and configuration to be retained.

Standard multi-box reversal construction keeps X and O in separate columns. One-box variants also exist, including the one-step-back rule, which can place both symbols in the same column in a defined circumstance. That is a methodological exception, not a charting error.

Vertical or horizontal counts convert the height of a column or width of a congestion into a P&F price objective. The formula, starting column, projection point, and activation rule vary across schools and software. These objectives are parameter-dependent estimates, not prices the market must reach; the Wyckoff workflow is covered separately in P&F cause count.
