We're working on getting out a pre-beta in the next few days. It will have tick charts. This includes raw ticks, n-trades/bar, and n-seconds per bar.
eg: 20T is 20 ticks/trades per bar, 20s is 20 seconds per bar, T is plain old raw tick. I'm talking about the "interval" that you would enter.
I'm attaching a few pictures so you get a preview. Attached to this is a raw tick chart. The red line is the bid, green ask, black trades. There are dots to denote the trades. The lines can be drawn as square waves or straight lines between dots. Also, you can turn on/off the bid/ask/trade lines as well as the dots.
