Hello Granit,

Thanks for your post.

AddPlot() would be used to add plots to your script. AddDataSeries() could be used to add additional secondary data series to your script.

You could create two double variables named something like close1 and close2 that will hold the Close value of each data series. Then you could create a Series<double> variable named something like diff and assign close1-close2 to that Series<double> variable and assign the diff variable to a plot.

For example, you could use close1 = Closes[0][0] to assign the Close price of the primary series to your first variable. close2 = Closes[1][0] would be used to assign the Close price of the added series to the close2 variable. You would subtract those variables and assign the value to diff, such as diff[0] = close1 - close2. Then assign the diff value to the plot, such as Values[0][0] = diff[0].

See the attached example script demonstrating this.

Something similar would be done to plot the ratio between two instruments. You would need to calculate the ratio between both instruments and assign that value to a plot.
