I find an Intermarket Indicator and wonder if one can plot this in ProReaTime.
The mainchart is the SPY. The sub chart are the RSI of XLB, GLD and EURUSD. And the last is the signal bar. See attached screenshot.
Not possible, you’ll have to open chart of each of the instrument and add RSI on it, then eventually, detach the indicator panel from the price chart and place it elsewhere below your SPY chart. But in any case, all the RSI will be set in an individual window.
