Force ODBC database re-query in every 1 second not 5 seconds?

What's the way to force ODBC database re-query in every 1 second not 5 seconds? I found that if I press F5 key, I can update chart realtiming when I press it. But writing " RequestTimedRefresh( 1 );" to AFL is still re-query once by 5 seconds.

ODBC sources are available so you can get them, change, recompile and that's it. But ODBC is slow and requery every 1 second may be too much. Much better use native database - it is order of magnitude faster than ANY external database.

It's difficult for me to compile the source code.is it possible to refresh chart every 1 second with AFL sentence?
