traderspost for thinkorswim trade automation

Until you posted this question I had never even heard of "traderspost". So no, I have nothing to say on this topic.

Whenever I need an automated trading solution I just build the chart strategy in TradeStation and rely on a rock solid trading platform to handle this very important task.

For anyone considering a fully automated trading system, I suggest you read the following article which explains some of the major pitfalls and limitations:

Then ask yourself, why would you need a third party solution when there are trading platforms available which already handle fully automated trading? Trading platforms which support thie feature are constructed to include all of the most important safe guards and limitations to ensure an accurate result. Repainting signals? With TradeStation you never have to worry about that. Because the platform itself makes it impossible to construct a chart strategy with signals that repaint.

Final thoughts. There is no need to reinvent the wheel here. Just use a trading platform which already handles automated trading. Don't complicate things. Keep it simple.
