It works if you get the syntax correct
If you want the results in a scan you need to replace the GetChartID()
with the actual number for that chart pane, and you get this from the
chart parameters window
Apply this to a new chart pane
if( status("Action")==1 ) Chart = GetChartID();
else Chart = 2628; // from parameter window for chart ChartID
buy = cross( close, study( "RE" , Chart ) );
sell = cross( study( "SU" , Chart ), close );
SetChartOptions( 0, chartShowDates|chartWrapTitle );
GraphXSpace=10;
_N(Title = "{{NAME}} - {{INTERVAL}} {{DATE}} "+_DEFAULT_NAME()+" :
{{OHLCX}} {{VALUES}}" );
Plot( C, "", ParamColor( "Price Colour", colorGrey50), ParamStyle(
"Price Style", styleBar, maskPrice ) );
PlotShapes( shapeUpArrow*Buy, colorGreen, 0, L, -12 );
PlotShapes( shapeDownArrow*Sell, colorRed, 0, H, -12 );
it will only provide results for the section of chart that contains
the drawn, named study. The study name can only apply to one line, so
each line will need its own unique studyID name
eg, say you have 10 lines and name them S0,S1,S3,...S9 then use
sell = 0;
for( n=0;n<=9;n++)
{
sell = sell or cross( study( "S"+n , Chart ), close );
}
