Dominick, I chart the bid, offer, and trade. This is easy to do using RealTick III. Just use their "time and sales" chart type.

You have to change a couple of the dumb defaults to make it useful, though. Turn OFF bid size and ask size! I plot the bid in green, the offer in red, and trades in yellow, on a black background. This gives you a nice "envelope" around the trades.

Apparently, this chart wasn't actually designed to be a chart. I beleive it was originally done as a quick kludge to provide a time-and sales tabular chart, since RT3 already had the ability to bring up a listd of the data points in a chart. That's my theory, anyway, which would explain the presence of the bid size and ask size, which are not very meaningful when plotted.
