The macOS version of Investor/RT supports the display of crosshair price and time in the main toolbar message area as you move the crosshairs. To enable this feature, access the chart's preferences using Command-Click inside the chart and choose Preferences → Chart. Inspect the Options tab in the Preferences window. Check the box entitled Show Mouse Feedback in Main Toolbar. Thereafter, as you move the crosshairs within the chart, the main toolbar message area will display the price and time at the intersection of the crosshairs.
Another option for Mac users is adding the InfoBox Indicator to charts which can be customized to show many different statistics in addition to just time and price.
