Re: [amibroker] using global variables in multi-time frame

[Graham <kavemanperth@xxxxxxxxx>]

2 ways you would need to do this as procedures do not provide any real
output, only an action

METHOD 1

X =Y = 0; //initialise global variables on first pass through code

procedure Test(TimeFrame)
{
   TimeFrameSet( Timeframe );
       ...now process some stuff and allocate values to the global
variables ...
   X = xx;
   Y = yy;
   TimeFrameRestore();
Plot(TimeFrameExpand(X,Timeframe ,expandLast), "", colorblue);
Plot(TimeFrameExpand(Y,Timeframe expandLast), "", colorblue);

}

Test(indaily);
Test(inweekly);




METHOD 2


X =Y = 0; //initialise global variables on first pass through code

procedure Test(TimeFrame)
{
Global x;
global y;
   TimeFrameSet( Timeframe );
       ...now process some stuff and allocate values to the global
variables ...
   X = xx;
   Y = yy;
   TimeFrameRestore();
}

//now call on the procedure in daily time frame and plot
Test(inDaily);
Plot(TimeFrameExpand(X,inDaily,expandLast), "", colorblue);
Plot(TimeFrameExpand(Y,inDaily,expandLast), "", colorblue);

//now call on the procedure in weekly time frame and plot
Test(inWeekly);
Plot(TimeFrameExpand(X,inWeekly,expandLast),"",, "", colorred);
Plot(TimeFrameExpand(Y,inWeekly,expandLast),"",, "", colorred);
