MACD crossover AFL to send an email ALERT RT not working

[pankbaw]

Hi All,

I've coded a simple MACD crossover AFL to send an email ALERT RT when the crossover happens to the upside/downside. And I have also changed the amibroker settings to send email alerts. I'm using True data downloader for RT data. But still, when the crossover happens the alerts are not generated.
Please, can somebody look at the afl below and suggest what's wrong.

PFA screenshot for reference.

_SECTION_BEGIN("");
SetChartBkColor(ParamColor("Panel color ",colorBlack));
r1 = Param( "Fast avg", 12, 2, 200, 1 );
r2 = Param( "Slow avg", 26, 2, 200, 1 );
r3 = Param( "Signal avg", 9, 2, 200, 1 );
Plot( ml = MACD(r1, r2), StrFormat(_SECTION_NAME()+"(%g,%g)", r1, r2), ParamColor("MACD color", colorRed ), ParamStyle("MACD style") );
Plot( sl = Signal(r1,r2,r3), "Signal" + _PARAM_VALUES(), ParamColor("Signal color", colorBlue ), ParamStyle("Signal style") );
Histogram_color = IIf( ml-sl > 0, colorBlue, colorRed);
Plot( ml-sl, "MACD Histogram", Histogram_color, styleNoTitle | ParamStyle("Histogram style", styleHistogram | styleThick | styleNoLabel, maskHistogram ) );
Title = EncodeColor(colorWhite)+ "";
_SECTION_END();

x = ml;
y = sl;

Buy=Cross(x,y);
PlotShapes(shapeUpArrow*Buy,colorBlue);
Sell=Cross(y,x);
PlotShapes(shapeDownArrow*Sell,colorYellow);


AlertIf( Buy, "EMAIL", "MACD Crossover "+FullName(), 1 );
AlertIf( Sell, "EMAIL", "MACD Crossover "+FullName(), 1 );

//AlertIf( Buy, "SOUND C:\\Windows\\Media\\notify.wav", "Audio alert", 2 );
//AlertIf( Sell, "SOUND C:\\Windows\\Media\\chord.wav", "Audio alert", 2 );


/* End - MACD Crossover */

[/CODE]
