Hello,
New to TOS and thinkscript. I was wondering if there were any thinkscript coders in here? What I would like to know is how to add a moving average on to an indicator, to use as a signal line or showing trend. I would like to add a mov. avg. on the RelativeStrength line that compares two markets to each other. This is NOT the RSI like wilders. And also on the OnBalanceVolume. And of couse be able to add an avg. to basicly any indicators once I learn what to do.
Or is there a better forum to ask about this?
Any info would be helpful.
Not sure why you can't just in TOS thinkdesk just click on an indicator and it have a way to just add an avg. or another indicator to that indicator?
