[amibroker] How To Get HHV( High, between 09:30 and 10:30 )

[Lester Vanhoff]

I need the following code for intraday data (one-minute database):

1) HHV( High, between 09:30 and 10:30 );

2) Close (at 10:30);

Then I would need to plot those as horizontal lines each day from their start 
time till the end of the day.

Tnx
