Thank you Antt, but not what I was looking me. I would insert a text as in this example: RSI +-value of CSR.... is possible?

Thank you Antt is perfect.

Now: I would fix the text in a specific point in sub-Window.

I added:  objprop_xdistance    but not function. Why ?

Thank you again

wooooow....... beautiful Antt, it is what I was search....

  Now, if possible again I ask your help: I have built this CCI but I cannot  look and change color to histograms when the CCI is above or below the  of zero line. Why?

Thank you for  help
