Guys Please Help, I can't figure it out how to make bollinger band line go to the front and not at behind of the candle:
BOL

_SECTION_BEGIN("Bollinger Bands");
P = ParamField("Price field",0);
Periods = Param("Periods", 14, 2, 300, 1 );
Width = Param("Width", 2, 0, 10, 0.05 );
Color = ParamColor("Color", colorCycle );
Style = ParamStyle("Style");
Plot( BBandTop( P, Periods, Width ), "BT" + _PARAM_VALUES(), colorGrey50, styleNoLabel ); 
Plot( BBandBot( P, Periods, Width ), "BB" + _PARAM_VALUES(), colorGrey50, styleNoLabel ); 
_SECTION_END();

this just default bollinger code..

Any solution or code that i need to add ??
Thanks

In the two Plot() functions, you can change the Zorder value to something higher than default 0, like 2.

It is explained here in detail:

Or change the ordering of Plot() calls.

Thanks guys, you are so kind to help :+1:t2:

i just add " graphzorder = 1; "

_SECTION_BEGIN("Bollinger Bands");
graphzorder = 1;
P = ParamField("Price field",-1);
Periods = Param("Periods", 14, 2, 300, 1 );
Width = Param("Width", 2, 0, 10, 0.05 );
Color = ParamColor("Color", colorCycle );
Style = ParamStyle("Style");
Plot( BBandTop( P, Periods, Width ), "BT" + _PARAM_VALUES(), colorGrey50, styleNoLabel ); 
Plot( BBandBot( P, Periods, Width ), "BB" + _PARAM_VALUES(), colorGrey50, styleNoLabel ); 
_SECTION_END();

You were not supposed to use or set the graphzorder = 1; special variable.

Instead, you are supposed to define the ZOrder for the specific Plot() calls that you want to affect.

Only these two lines are supposed to be changed:

Plot( BBandTop( P, Periods, Width ), "BT" + _PARAM_VALUES(), colorGrey50, styleNoLabel, NULL, NULL, 0, 2 ); 
Plot( BBandBot( P, Periods, Width ), "BB" + _PARAM_VALUES(), colorGrey50, styleNoLabel, NULL, NULL, 0, 2 );

Look at the code above and just modify those parameters. Changing graphzorder is a completely different thing.
