Hi
I need some help to apply the same study to several symbols in the lower region.
It can be simple one for this example - if the 8 EMA above the 21 EMA then plot a green dot, otherwise plot red dot.

I can only display the first symbol, the rest do not appear.
How can this be done?

You will have to hold have each ticker in the study itself. Something along these lines is typical way to handle that

 

Code

declare lower; input length = 20; input symbolOne = "SPY"; input symbolTwo = "DHR"; input symbolThree = "INTC"; def c1 = close(symbolOne); def c2 = close(symbolTwo); def c3 = close(symbolThree); plot DataOne = RSI(length = length, price = c1); plot DataTwo = RSI(length = length, price = c2); plot DataThree = RSI(length = length, price = c3);

Thank you !
It definitely gave me direction to move forward
