Re: [amibroker] TJ: AWK like BEGIN/END structure in AA for Composites?

["Richard Alford" <richard.alford@xxxx>]

Thanks TJ - for the coming new structures and dynamic portfolios - I'm not
trying to dig the spurs into you <g>.

And thanks for all the hidden changes - just discovered you are reporting
the date range and input range in the report summaries - very much
appreciated. You may not be able to keep everyone happy all the time but
you sure get close!

Cheers,

Richard
