Friendly, helpful, email-based support. Get this if you think you will need some help to understand what the model is doing, how it works and if you are doing things right.
The support lasts for 1 month after purchase but you can always extend it, or become a Member and get even more!
This does not include programming help. But there are lots of articles and videos to help you with this. And if you need custom modifications to suit your strategy or trading style you can get these too.
