You mean something like this?

// === print value which are manually given by user

// --- extern:
// --- pivot data
//Res3=12500
//Res2=12400
//Res1=12300
//DPiv=12200

//Sup3=11900
//// --- open,high,low,close
//Op=12250
//Cl=12110
//Hi=12340
//Lo=12050
// --- for quick turn on/off lines
//HideAll=0

IF NOT HideAll THEN
// --- R3-R1 red

ENDIF

RETURN

For quick adding make the values extern.

Yes, of course we can simply use RETURN variablename AS “Human Name in Indicator Adjustment”, the only disadvantage (for me personally) is that I cannot switch on/off all the lines with a single “check box” because an indicators last command must be a RETURN command of some kind. So I cannot do something like

IF NOT HideAll THEN

RETURN varname as “Human Name”

ENDIF

because here we have ENDIF as the very last thing and that’s not possible. So if you want to adjust the lines as for example in the normal Pivot Indicator you must set each line separately to “not shown” if you need a clean chart without all the lines. But here we go with the code:

// === print value which are manually given by user

// --- extern:
// --- pivot data
//Res3=12500
//Res2=12400
//Res1=12300
//DPiv=12200
//Sup1=12100
//Sup2=12000
//Sup3=11900
//// --- open,high,low,close
//Op=12250
//Cl=12110
//Hi=12340
//Lo=12050


RETURN Res3 as "R3", Res2 as "R2", Res1 as "R1", DPiv as "Piv", Sup1 as "S1", Sup2 as "S2", Sup3 as "S3", Op as "O", Hi as "H", Lo as "L", Cl as "C"
