To begin creating Ratio Charts, simply search for an instrument by clicking on the magnifying glass icon up at the top left corner of your platform. After that, you will see two columns of icons towards the left of your search. Selecting the 1:1 icon will turn the chart into a Ratio Chart using the symbol that was already on the chart and the symbol you searched for.
Reminder: Be sure to overlay and add indicators on to your Ratio Charts for future technical analysis! Just right-click your chart and go to Add Indicators to get to the Indicator Menu!
