I everybody,

First of all, Let me talk about what I'm doing.

I add three series to the ultrachart ("Max" ,"Min" and "serial" series ones in the picture).

Max = red line

Min = Green line

serial = blue line

"Max" and "Min" series help us to see the behavior of our parameter to qualify for a period of time,
if it meets our specifications.
So, Here come the questions, I don't know if this it's posible to do:

How can I disable tooltips in the "Max" and "Min" series?
I mean, allow tooltips only in the "serial"  serie.

How can I change the line styles of the series?
I want to use Dash for the red and green series and solid for the blue serie.

How can I use Symbol Icon only in the blue serie?

I was looking some information about this but I have not had succes.

I hope somebody can help me.

This is my code.

By the way, I was using target line example to do this but I had to leave it because it doesn´t work properly in my results and what I expect when I set changes in the specifications (Max and Min Series).
