Date Range On Screen Scaling

The range setting is based on the highest and lowest on screen values in the y-axis (price axis) for a specific subgraph. For example, if the highest and lowest values of a chart's on screen data are 20 and 10 respectively, your chart uses values slightly higher than the highest value (20) and slightly lower than the lowest value (10) as its y-axis scale. If a data stream's (or study's) highest high and/or lowest low on screen values change while scrolling left or right, the y-axis scale adjusts accordingly.
