you need static variable to avoid this.
if you want this to trigger only once you could use:
rgds, Ed
myvar= StaticVarGet( "BB" + Now(4) );
if ( EndSessionTrigger AND myvar)
{
Say( "Book your Position Book your Position Book your Position Book your
Position" );
Plot( 1, "Book", colorWhite , styleArea | styleOwnScale, 0, 1 );
StaticVarSet( "BB" + Now(4), 1);
}

Subject: [amibroker] Timer Help Needed
Dear Tomasz Janeczko and Group Members,
I am trading in National stock Exchange of India.I am using a timer
in my af whose code is given below.
At 3.21 pm it tells me once to "book my position".
The problem is - if i change my end time to any earlier time like say
12.30 pm ,the afl starts saying "book your position" but it does not
stop saying "book your position", till i shut down my amibroker.
Timer Code:
-----------------------
SetChartOptions( Mode = 1, Flags = 1, gridFlags = 0, ymin = 0, ymax =
0 );
//********************************************************************
****************************************************
_SECTION_BEGIN( "SESSION TIMING" );
TimeFrame = Param( "Chart Timeframe (min)", 8, 1, 60, 1 ) * 60;
TimeFrameSet( TimeFrame );
TN = TimeNum();
ParamStartTime = ParamTime( "Session Start", "09:54:00" );
ParamEndTime = ParamTime( "Session End", "15:21:00" );
InSessionTime = TN >= ParamStartTime AND TN <= ParamEndTime;
StartOfSession = InSessionTime > Ref( InSessionTime, -1 );
EndOfSession = InSessionTime < Ref( InSessionTime, -1 );
InsessionTime = InSessionTime OR EndOfSession;
_SECTION_END();
//********************************************************************
****************************************************
RequestTimedRefresh( 1 );
ParamDateNumber = ParamDate( "Date", Now( 1 ), 0 );
RTTimeNumber = Now( 4 );
RTDateNumber = Now( 3 );
InSessionDate = RTDateNumber == ParamDateNumber;
PreSessionTime = RTTimeNumber < ParamStartTime;
PostSessionTime = RTTimeNumber > ParamEndTime;
InSessionTime = NOT ( PreSessionTime OR PostSessionTime );
PrevInSession = StaticVarGet( "InSession" );
InSession = InSessionDate AND InSessionTime;
StartSessionTrigger = LastValue( InSession ) > PrevInSession;
EndSessionTrigger = LastValue( InSession ) < PrevInSession;
StaticVarSet( "InSession", InSession );
//********************************************************************
****************************************************
if ( EndSessionTrigger )
{
Say( "Book your Position Book your Position Book your Position
Book your Position" );
Plot( 1, "Book", colorWhite , styleArea | styleOwnScale, 0, 1 );
}
//********************************************************************
****************************************************
Kindly help me in rectifying the problem.

Bobby Kular
