What this is

Jelly Charts replays 1-minute futures bars you upload, records the reasoning behind each decision before the result is known, backtests rules against that data, and can have an AI agent draft a strategy in Python. It is run by one person, not a company with a support desk.

Not financial advice

Nothing produced by Jelly Charts is financial, investment or trading advice. Replays, journal analytics and backtests describe the past. They do not predict the future. Trading futures involves substantial risk of loss and is not suitable for everyone. Every decision you make with your own money is yours alone.

Your account

Sign-in is by a link emailed to your address; the link works for 15 minutes and the resulting session lasts 30 days. Keep the link and the device to yourself. One subscription is for one person.

Your data

You keep ownership of everything you upload and everything you write. You are responsible for having the right to use the market data you upload — Jelly Charts supplies none of it and redistributes none of it.

Payment and cancelling

The subscription is $8.33 a month, charged through Stripe. You can cancel at any time from Billing inside the app and you keep access until the end of the month you have paid for. There are no automatic refunds for a partial month; if something went wrong, email and it will be sorted out.

Availability

The service is provided as it is, with no guarantee of uptime, of a particular result, or that it will keep running forever. If it is going to be shut down you will be told by email with enough notice to export your journal.

Acceptable use

Do not attempt to reach another account's data, do not resell access, and do not use the AI agent to generate anything unlawful.

Ending the agreement

You may stop at any time by cancelling. Access can be ended on notice if a payment fails or if the acceptable-use paragraph is broken; in either case you can ask for your data to be exported and deleted.
