Box Size and Reversal Criteria
Determine the box size and reversal criteria. The box size determines the price range of each box on the chart, while the reversal criteria determine when a new column is started on the chart. These parameters are important as they can affect the sensitivity and accuracy of the chart.
Consistent Price Scale
Use a consistent price scale. Point and Figure charts are not time-based but rather based on price movements. A consistent price scale on the chart is essential for accurate analysis and comparison.
