FAQ
Common questions.
The trial, paying, and how to describe a strategy.
Do I need a card for the trial?
No. You get a batch of free backtests right away — your account page shows how many you have left. You only pay when you choose a plan and check out on Stripe.
Where do I pay?
On Stripe's secure page. After you pay, you land back in the app. We do not store your card here.
Are you a broker?
No. Tenachine is for learning and research. We do not place trades, hold money, or give personal advice. The terms spell it out.
How do I write a strategy?
Say when you enter, when you exit, and which indicators you mean. Keep the first version small. See this page or the full guidelines.
Can I cancel?
Yes. Use Stripe to cancel or change your plan whenever you need to.
