P&F charts have the added advantage of speeding up or slowing down price, simply by doing 2 things - changing the box size and reversal count of the chart.
Unlike bar/candlesticks charts where changing the unit of time (week to day, day to minute, etc.) is supposed to "speed" up the chart; in doing so, you are just changing the unit of time but will have to accept the OHLC prices for that unit of time. You are not making price more/less sensitive in the chart.
Box Size: Price Range Scaling
The traditional scaling of box sizes for P&F charts uses static box sizing adjusted for the price range of the underlying product:
Price Range (Underlying) Box Size
Under $0.25 0.0625
0.26 to 1.00 0.125
1.01 to 5.00 0.25
5.01 to 20.00 0.50
20.01 to 100.00 1.00
100.01 to 200.00 2.00
200.01 to 500.00 4.00
500.01 to 1,000.00 5.00
1,000.01 to 25,000.00 50.00
25,000.01 and up 500.00
My view is using a percentage … is a truer scaling method because it treats price as a continuous variable for which all price points are valid on a logarithmic scale.
The traditional method tends to round down or round up decimals and this loses the sensitivity in the box size. Also, the rounding up or rounding down disproportionately compresses or stretches the trend lines and price targets. Percentage scaling is the reliable and accurate method to use. And this is the method adopted by the Home Options Trading process.
