Price Scale Properties
Various adjustments can be made to the Price Scale, such as the font size, logarithmic scale, the number of decimal places, and the price scale intervals used. Enable the Show in Price Scale property for the chart or tool to display in the scale, either the last value, the percentage change, or both.
The colour of the label will match the colour of the last bar or tool:
To display the following Price Scale Properties you can either right click on the Price Scale or you can left-click on the Price Scale which will then display the Properties in the Control Panel (if open).
Price Scale Properties
Auto Maximum: When enabled, Optuma will automatically adjust the highest price the scale displays to as you scroll through the chart.
Auto Minimum: When enabled, Optuma will automatically adjust the lowest price the scale displays to as you scroll through the chart.
Auto Range: When enabled, Optuma will automatically set the price range covered by the scale, so that all data on the page is within view.
Auto Start Price: By default, all price scales start at zero. Unticking the Auto Start Price option gives you the option of adjusting the starting value of your price scale. This in effect works as a type of vertical offset for your charts data.
Auto Price Step: Automates the price steps and scale for the grid (when enabled).
Show Depth Information: If your chart is sourced from a real-time data vendor, you can opt to display Market Depth values in your price scale. Unticking this option will hide the depth information from view.
Show Alerts: When selected any active Price Alerts will be highlighted in the Price Scale.
Cursor Tracks Price and Date: When enabled the date and price will be highlighted on the Price and Date scales in relation to the current cursor position.
Show Min/Max Price: When selected, for the bars that are in view the highest high and lowest low values will be displayed in the Price Scale.
Extend Scales: Enabled by default the Price Scale will extend to the full height of the chart. If deselected the Price Scale will only display a scale range applicable to the bars that are in view. For example, if the chart is compressed vertically then the Price Scale will also be reduced.
Logarithmic Scale: Logarithmic charts allow you to see vertical changes in terms of percentage rather than price. For example, on a chart using a Logarithmic Scale the vertical distance between $10 and $20 (a 100% increase) is the same as the vertical distance between $50 and $100. Because these charts show percentage relationships, logarithmic scaling is also called “percentage” scaling. It is also called “semi-log” scaling because only one of the axes (the vertical one) is scaled logarithmically.
Scales Font Size: Sets the size of the Price Scale values. To adjust the font size, click and drag the slider, left to make the values smaller or right to make the text larger.
Price Scale Layer: Sets which chart layer is used for the Price Scale values. If you are using overlayed charts then you can switch to a different chart layer and display the price scale for that chart.
Price Display Format: Displays the number of decimal places displayed in the Price Scale. You can adjust this value if you wish to increase / decrease the decimal settings used on a particular chart.
Price Highlight Display: When the chart/tool Show Price property is enabled the Last Price, % Change, or Both can be shown in the price scale
Price Scale Major Line Style: Only applicable when grid lines are enabled. Allows adjustment of the Price Scale Major line style, width, colour, and transparency.
Price Scale Minor Line Style: Only applicable when grid lines are enabled. Allows adjustment of the Price Scale Minor line style, width, colour, and transparency.
