Wilders RSI-20 and Wilders RSI-75 in the same pane.  An Scan condition can be created separately on each, but can a scan condition be created to, say, show the RSI-25 greater than the RSI-75?  If I have a 20 sma and a 40 sma plotted on the bars in the top pane, one of numerous scan condition options available include 20 sma above 40 sma, 20 sma below 40 sma, etc.  Such options are not available in the pane with RSI-25 & RSI-75.

If you are not getting the option to create conditions comparing a 25-period RSI and a 75-period RSI plotted in the same pane, then the indicators are probably not being plotted in the same scale.

Click on one of the RSI indicators and select Scaling. Then click on the Scale With drop-down menu and choose the other RSI indicator from the list.
