Popup alert in Amibroker-problem of multi popups

rvlv · Jan 18, 2013

Hi friends
here is a code for pop up alert.
problem is many popups keep coming.

can a expert suggest a way out please!
//==================================================
_SECTION_BEGIN("POPUP");//pop up alert

Buy=MACD()>SIGNAL();
SELL = MACD()<SIGNAL();
PlotShapes( IIf( Buy, shapeDownArrow + shapePositionAbove, shapeNone ), colorGreen );
PopupWindow("Buy : " + FullName(),"Alert", 5, 640*mtRandom(), 480*mtRandom());

PlotShapes( IIf( Sell, shapeUpArrow + shapePositionAbove, shapeNone ), colorRed );
PopupWindow("Sell : " + FullName(),"Alert", 5, 640*mtRandom(), 480*mtRandom());

_SECTION_END();

========================
Once this code lines are added to an afl,after removing buy,sell code lines, it will give popups.

but there are multiple popups allover the chart.
I am looking for just a single buy or sell alert from one chart where the afl has the above code lines.

thanks in advance
regards

use exrem to reduce excessive signals.

Buy=Exrem(Buy,Sell);
Sell=Exrem(Sell,Buy);

use this

Popup Window: Preventing pile-ups

By Dennis Brown

The popup window is a great tool in debugging and can help you to keep track of what your code is doing or it can be used to alert you to special situations in your normally running formula. A common problem is that if you call PopupWindow() from a loop or if one gets generated on every AFL pass, you can get hundreds or even thousands of pop-ups piling up on your screen. Tomasz posted a simple work-around on the AmiBroker Feedback Center that took care of the problem in some cases (Suggestion 1528):

The following is a more complete version of this solution that adds a popupID to keep track of each individual popup window and re-enable the popup after its specified timeout period, or if any of the displayed text changes:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23

function GetSecondNum()
{
Time = Now( 4 );
Seconds = int( Time % 100 );
Minutes = int( Time / 100 % 100 );
Hours = int( Time / 10000 % 100 );
SecondNum = int( Hours * 60 * 60 + Minutes * 60 + Seconds );
return SecondNum;
}

function PopupWindowEx( popupID, bodytext, captiontext, timeout, left, top )
{
displayText = bodytext + captiontext;
if ( ( StaticVarGetText( "prevPopup" + popupID ) != displayText) OR ( StaticVarGet( "prevPopupTime" + popupID ) < GetSecondNum() ) )
{
StaticVarSetText( "prevPopup" + popupID, displayText);
StaticVarSet( "prevPopupTime" + popupID, GetSecondNum() + timeout );
PopupWindow( bodytext, Captiontext + popupID, timeout, Left, top );
}
}

PopupWindowEx( "ID:1", "testing", "test alert ", 5, -1, -1 );
PopupWindowEx( "ID:2", "testing", "test alert ", 5, 0, 0 );

Hi subroto
please take a look at this.
can you fix this popupwindow problem-two windows come both buy & sell.
actually in a sell time,only sell popupwindow should appear.but buy also shows up.
the window has to be linked to time of alert buy signal or sell signal

thanks
regards

Hi subroto ,Smart trade

please take a look at this afl.
please find a way out to get only one popupwindow alert when a buy signal or sell signal comes.

one guy when asked ovr chat told me-"Right now Amibroker is not geared for this kind of alert -use MT4"
I like only Amibroker .

thanks

	totalsec = hr * 60 ^ 2 + mnt * 60 + sec;	
	left =  Interval() - totalsec % Interval();
	return left;
}
 
function PopupWindowEx( popupID, bodytext, captiontext, timeout, left, top )

    displayText = bodytext + "_" + captiontext;
    if ( ( StaticVarGetText( "prevPopup:" + popupID ) != displayText) OR
