[amibroker] Williams%R Cloud - Can someone recreate using negative ChartGrid values?

[gmorlosky]

Below is a working RSI_Cloud. Can anyone make this a Williams%R_Cloud ?

Title = "RSI Cloud";

SetChartOptions(0,0,chartGrid30|chartGrid70);

Plot(RSI(14), "RSI Cloud", colorBlue, styleLine);

SetChartOptions(0,0,ChartGrid30 | ChartGrid70 ); 
r = RSI(14); 
Plot( r, "RSI", colorBlack ); 
PlotOHLC( r,r,50,r, "", IIf( r > 50, colorRed, colorGreen ), styleCloud 
| styleClipMinMax, 30, 70 );
