How do you use Tradestation or Ameritrade with v1.74?

I just downloaded the free version and I don't have accounts with any of the few listed brokers. But, the software is supposed to work with many brokers, including Tradestation and Ameritrade. How do I do that, or do I need a different version? I trade stocks, options, and futures and will be trading FX soon.

I somehow missed this question from a month ago.

I am writing a plugin for Sierra Chart, which supports TD Ameritrade, among several other brokers.

I expect to be done in less than a month.

Are there news about it?
