what is the scale used to put more on indicator in the same separate window ?

 

Hello 

If you put a RSI(30) and a CCI(14) in a same separate window you can see crossings but the 'real' value of those indicators dont crossing.

So how to automatize a trading system based on those crossings ?

 

So i think ML4 calculat a scale ? But how to calculate it ?

 

Thanks for your help.
