A point and figure chart plots only meaningful price changes and ignores time. Rising prices appear as columns of Xs and falling prices as columns of Os, and a new column starts only when price reverses by a set amount. Days with small moves add nothing to the chart, which leaves a cleaner record of trends, breakouts, and the price levels where buyers or sellers took control.

How P&F differs from time-based charts

Bar, line, and candlestick charts give every period the same horizontal space, so a quiet day takes as much room as a volatile one. A point and figure chart adds a mark only when price travels far enough to matter under the chartist’s settings. A stock that drifts sideways in a narrow band for three weeks may add nothing, while a sharp two-day sell-off may add an entire column.

Many traditional practitioners chart from closing prices only, so intraday swings that reverse before the close never appear.

Building the chart: box size and reversal amount

Box size

The box size is the unit of price measurement. With a $1 box, price must rise a full dollar above the top of the current X column to add another X. A move of $0.80 adds nothing. For a stock in a falling column, the same rule applies to each new O.

The chartist chooses the box size, and the choice controls how much detail the chart shows:

• Fixed box size. A set dollar or pip value, such as $0.50, $1, or $2 for a stock, or 10 pips for a currency pair.
• Traditional scale. A sliding scale that widens the box as price rises. One widely used version assigns $0.25 boxes below $5, $0.50 from $5 to $20, $1 from $20 to $100, $2 from $100 to $200, and $4 above $200.
• Percentage box size. Each box equals a fixed percentage of price, which keeps the chart comparable across price levels.
• Volatility-based box size. Some charting software sets the box from a measure such as average true range, so the box adjusts to how much the instrument typically moves.

Smaller boxes produce more columns and more signals, including more false ones. Larger boxes produce fewer, slower signals that respond only to bigger trends.

Reversal amount

The reversal amount sets how far price must move in the opposite direction, measured in boxes, before the chart starts a new column. The three-box reversal is the classic setting. With a $1 box and a three-box reversal, a rising X column switches to an O column only after price falls $3 from the column high.

A one-box reversal shows almost every swing and produces a busier chart. Larger reversals, such as five boxes, show only major swings. Changing the reversal amount changes signals and price targets, so it should stay fixed when comparing charts.

Close-only vs. high-low method

In the close-only method, only the closing price is evaluated, usually once per day. In the high-low method, the chartist checks the day’s high when the current column is X and the low when it is O. If price extends the current column, plot it and ignore the opposite extreme; if not, check whether the opposite extreme triggers a reversal. The high-low method reacts faster and the close-only method filters more noise, so the two can produce different charts from the same price history.

Worked example: a three-box reversal

Assume a stock is in a rising X column that tops at $25, with a $1 box and a three-box reversal.

1. Rising column. The X column extends up to $25. Any close of $26 or higher would add another X.
2. Reversal down. For a new O column, price must fall to $22 ($25 minus three $1 boxes). A close at $23 changes nothing. When the stock closes at $22, the chart moves one column to the right and plots Os at $24, $23, and $22. The new O column begins one box below the top of the X column.
3. Continuation down. The stock keeps falling to $20, so Os are added at $21 and $20.
4. Reversal up. A new X column needs a rise to $23 ($20 plus three boxes). At $23, the chart moves right again and plots Xs at $21, $22, and $23.

The result, with the first X column starting from $21:

Each column contains at least three marks because a three-box reversal requires it. The chart shows that price swung from $25 down to $20 and back to $23, without showing whether that took four days or four months.

Reading the chart: supply, demand, and signals

Point and figure analysis treats price as a contest between supply and demand. A rising X column shows demand in control, and a falling O column shows supply in control. Comparing the height of each new column with earlier ones shows which side is gaining or losing strength.

Entry and exit rules

The core signals are breakouts:

• Buy signal (double top breakout): an X column rises one box above the high of the previous X column. In the example, if column 3 climbs to $26, it exceeds the $25 high of column 1 and generates a buy signal.
• Sell signal (double bottom breakdown): an O column falls one box below the low of the previous O column.
• Triple top and triple bottom: the same idea when price breaks a level that has stopped it twice before. A level tested more times is generally treated as more significant when it finally breaks.

Exits often use the opposite signal. A trader who bought a double top breakout might exit on the next double bottom breakdown, or place a protective stop one box below the low of the most recent O column. Because that stop sits a known number of boxes from the entry, risk per share is easy to measure for position sizing.

Support and resistance

Horizontal levels stand out clearly because the chart removes time. A row of O columns that bottom at the same price marks support, where demand has repeatedly absorbed selling. A row of X columns that top at the same price marks resistance, where supply has repeatedly capped rallies. A move through either level is the breakout or breakdown signal described above.

45-degree trend lines

Boxes are square, so P&F trend lines are drawn at 45 degrees rather than connecting highs and lows freehand.

• A bullish support line starts one box below the lowest O of a base and rises at 45 degrees. While price stays above it, the uptrend is considered intact.
• A bearish resistance line starts one box above the highest X of a top and falls at 45 degrees. While price stays below it, the downtrend is considered intact.

A break of the trend line is read as a possible change in trend, especially when it coincides with a breakout or breakdown signal.

Price objectives

P&F charts offer two traditional ways to project a target after a signal. Both are estimates, not forecasts that price must reach.

• Vertical count. Count the boxes in the column that produced the breakout, multiply by the box size and by the reversal amount, then add the result to the bottom of that column for an upside target. Example: a breakout column of 6 boxes, a $1 box, and a three-box reversal gives 6 × $1 × 3 = $18. If the column started at $20, the target is $38.
• Horizontal count. Count the number of columns across a sideways base or congestion area, multiply by the box size and the reversal amount, then add the result to the low of the base. A wider base implies a larger potential move.

Downside targets work the same way in reverse, subtracting from the top of the column or the high of the top formation.

Using P&F charts in different markets

The method works on any instrument with a price series: stocks, indexes, commodities, currencies, and crypto. In forex, box sizes are usually set in pips, and a trader could, for example, chart EUR/USD with a 10-pip box and a three-box reversal. On instruments that trade around the clock, the high-low method on intraday data can produce reversals that a close-only chart would never show.

Short-term traders can shrink the box size, but that reintroduces much of the noise the method was built to remove, and signals arrive more often and fail more often. For fast styles such as day trading, P&F is more often used to mark key levels on a higher setting than to time individual entries. It fits best with swing and position trading and with longer-term investing, where the goal is to stay with a major trend.

Limitations

• Settings change the chart. Two analysts using different box sizes, reversal amounts, or close-only versus high-low data can draw different charts and get different signals from the same prices.
• No time or volume. The chart cannot show how long a pattern took to form or whether a breakout came on heavy or light trading.
• Signals lag. Waiting for a full reversal or a breakout one box beyond a prior column means entries come after part of the move has happened.
• Gaps are filled in. A stock that gaps through several boxes overnight still gets one mark in each box, which can make the move look more orderly than it was.

The Bottom Line

Point and figure charts suit swing traders, position traders, and longer-term investors who want to follow major trends and spot clear support, resistance, and breakouts. The settings shape every signal, so choose a box size and reversal amount and keep them fixed. Remember that the chart hides time and volume, signals arrive after part of the move, and price targets are estimates only.
