Am I correct in interpreting the extension description to mean that you cannot use the Tradestation extension, and Tradestation streaming data, to form tick charts? Is IQFeed the only data provider with supported tick data? Tradestation advertises 180 days of historical tick data for futures and live tick-by-tick streaming.

Correct.
Okay. I'm on an IQFeed free trial right now. Streaming 100 tick for testing purposes. All AAPL 100 Tick and getting different charts. Any idea why this might be?

Just be aware that the IQFeed free trial may create 15-minute delays, which may create havoc with different Charts. You might get better synchronization between Charts if you use a time scale (such as 1-minute bars); otherwise, different ticks might enter different Charts at different times.
You can ask DTN to terminate your free trial early to a paid subscription if you need to.
Disclaimer: I don't have any personal experience with using tick data, although I do watch the partial Daily bar on WL Charts (which is driven by tick data). But IQFeed is the most responsive data provider that's supported by WealthLab.
