Testing is done for free with most brokers and trading platforms in simulator mode, so there's no need for TST for that.
Don't overlook the CME fees for data (starting at $85 per month) and the fact that TST's Combine-fees, which start at $95 per month, include those fees.
With a timeline like that, there's no doubt for me that I will fund my account myself.
If you have the capital to fund your own account, then you're not part of TST's target market anyway, are you?
