Historical Context
Point and Figure (P&F) charts date back to the late 19th century and were developed as a method for tracking and analyzing stock market trends. Unlike other charting methods that consider both price and time, P&F charts exclusively focus on price movements. This technique was popularized by Charles Dow, the co-founder of Dow Jones & Company and the Wall Street Journal, who utilized P&F charts to identify major price trends.
Key Features and Components
Price Increments
P&F charts track price changes using specific increments known as “box sizes.” Each box represents a predetermined price level.
Columns of Xs and Os
- Xs: Indicate an increase in price.
- Os: Indicate a decrease in price.
Reversal
- Reversal: A column shift from Xs to Os or vice versa, indicating a reversal in price direction. This shift occurs once the price movement surpasses a set reversal threshold.
No Time Axis
Unlike traditional candlestick or bar charts, P&F charts lack a time axis, emphasizing price changes only.
Creating Point and Figure Charts
Basic Steps
- Determine the Box Size: This is the price increment represented by each box.
- Set the Reversal Amount: The number of boxes needed to denote a trend reversal.
- Plot Price Movements: Use Xs for price increases and Os for price decreases, shifting columns when reversals occur.
Example
Suppose the box size is $1, and the reversal amount is 3 boxes ($3):
- If the stock price moves from $10 to $13, plot three Xs in the first column.
- If the price then falls to $10, shift to a new column and plot three Os downward.

Importance and Applicability
Trend Analysis
P&F charts are particularly effective for:
- Identifying long-term trends.
- Spotting key support and resistance levels.
- Determining buy and sell signals.
Usability Across Markets
These charts are versatile and can be applied across various financial instruments, including stocks, commodities, forex, and futures.
Examples and Case Studies
- Example: An investor uses a P&F chart with a $2 box size to track a stock. When the price moves from $50 to $56, they plot three Xs. A subsequent drop to $52 requires a new column with two Os, signaling a potential trend reversal.
Considerations
- Box Size and Reversal Setting: Appropriate settings are crucial for accurate trend identification.
- Market Conditions: P&F charts are less effective in highly volatile or thinly traded markets.
Related Terms and Comparisons
- Candlestick Charts: Include time intervals and show open, high, low, and close prices.
- Bar Charts: Similar to candlestick but use bars instead of candles.
- Renko Charts: Similar to P&F but use bricks to indicate price movements.
Interesting Facts
- P&F charts predate the computer era and were plotted manually by traders.
- They eliminate market noise by disregarding minor price fluctuations.
