| - | Traditional scaling uses a predefined table of price ranges to determine what the box size should be. The table was originally created by the people at "ChartCraft" and later popularized by Tom Dorsey in his book //[[https://store.stockcharts.com/products/point-figure-charting-the-essential-application-for-forecasting-and-tracking-market-prices-3rd-edition|Point & Figure Charting]]//. | + | Traditional scaling uses a predefined table of price ranges to determine what the box size should be.

| To keep it simple, the rest of this article will use the Percentage scaling method and a classic reversal amount (3). Percentage scaling means the box size will be a specific percentage of price. Interval refers to the data periods (daily, 60 minute, 30 minute etc...). The box-size and data interval will be changed to affect the look-back period on the P&F chart. Basically, P&F charts with smaller box sizes and shorter data intervals have shorter look-back periods. P&F charts with larger box sizes and longer data intervals have longer look-back periods. | To keep it simple, the rest of this article will use the Percentage scaling method and a classic reversal amount (3).

| - | The Russell 2000 P&F chart shows the key settings in the Chart Attributes section and the Chart Scale section. Notice how the numerical value of each box changes. The difference between the top two boxes is 8.36 (844.04 - 835.68) and the difference between the bottom boxes is 4.69 (473.94 - 469.25). Despite different sizes in absolute numbers, the boxes are equal in percentage terms (1%). 8.36 is 1% of 835.68 and 4.69 is 1% of 469.25. | + | The GE P&F chart shows the key settings in the Chart Attributes section and the Chart Scaling section. Notice how the numerical value of each box changes. The difference between the top two boxes is 1.15 (116.52 - 115.37) and the difference between the bottom boxes is 0.84 (85.59 - 84.75). Despite different sizes in absolute numbers, the boxes are equal in percentage terms (1%). 1.15 is 1% of 115.37 and 0.84 is 1% of 84.75. |
