[amibroker] Plotting indicators with selected area to be filled

["Habibur Md. Rahman Planning Networks" <habib@xxxxxxxxxxxxxxxx>]

Hi

I was trying to fill the area of RSI and defined threshold:
       when it is greater than 70 then the area enclosed by the line 70 and RSI itself
       when less than 30, then the area enclosed by the line 30 and RSI

I have changed the color based on the value of RSI and then used PlotOHLC function with styleCloud. But the output is not smooth...

here is the code:

periods = Param( "Periods", 15, 1, 200, 1 );
Plot( RSI( periods), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style")  );
mycolor = IIf(RSI(periods) <30, colorGreen,colorRed);
Up_Th = IIf(RSI(periods) <30, 30, RSI(periods));
Low_Th = IIf(RSI(periods) >70, 70, RSI(periods));

 PlotOHLC(Up_Th, Up_Th, Low_Th, Low_Th, "", mycolor, styleCloud);

I saw image of others plot of same thing which is very smooth. It seems some other effective way is there for filling area. Can anyone please help me?

Regards
Habib
