Dennis, I tried to use a 5 second database, but then the volume bar
view is "grayed out." If I set the database to ticks, using IQ Feed,
I can get volume bars, but I can only get a few days worth of data,
pretty worthless for backtesting and optimization. Exactly where can
I get the workaround for this? I don't know what Jerry meant by HQ.
Volume bars look interesting, but they're pretty worthless if I can
only get a limited history in the database.
