[amibroker] can't get the value of today's open in real-time exploration

["wel6" <e9981@xxxxxxxxx>]

Hello,

I am trying to use the value of today's open in real-time exploration.
The following code is used to test whether the value is correct or
not. I have yesterday's high right, but have no idea where the number
of today's open coming from. At AA window,range is set at "nlast
qutations, n=1", and "wait for backfill" is checked. Can anyone help
me find out what's wrong with the code? Thanks!
Ken

TimeFrameSet(inDaily);
a=H;
TimeFrameRestore();
b=TimeFrameCompress(O,inDaily);
m=Ref(TimeFrameExpand(a,inDaily), -1);
n=TimeFrameExpand(b, inDaily);
AddColumn(n,"today's open");
AddColumn(m,"yesterday's high");
Filter=1;
