You could use the RSI Weekly indicator (for daily periodicy charts) below as the basis for your
exploration. This indicator already has two PREV's in it (for Wilders Smoothing), and creating an
EMA would require a third. You would then need to duplicate that for monthly values (with an Monthly
RSI) and you now have a total of 6 PREV's to deal with.
Even though you are using short periods I estimate that you'll still need possibly as many as 1000
daily bars of data to give accurate RSI and EMA results from the monthly indicator. The resulting
exploration is going to run many times slower than three different periodicy explorations with
standard code.
I'll help you with creating the code if you really want to go that way but I think setting up three
explorations with the same code would be simpler.
