Line by line
A blank cell means the request is refused on that plan, not that the screen is empty.
The columns are transcribed from app/core/gating_matrix.py, the server
module that decides at request time whether a feature answers, so this table can be
diffed against the running code rather than taken on trust.

For a class or a trading group
A seat is a Pro subscription for that student, for as long as the cohort runs. At thirty seats that is $3.30 per student. Students do not pay separately and do not need a card.
The console shows the cohort in aggregate — participation, an eight-week consistency row, and which rules the group breaks most. It withholds every one of those figures until five students have been measured, and it never shows an instructor a single student's trades, emotion tags, or notes.
The first three teams get three months at no charge and keep $49 a month afterwards. In exchange we ask for a weekly call while you run the cohort, and permission to write up what happened. Educator plans are arranged directly rather than through the app stores — email us and we will set the cohort up.
Already have an account, or an invite link from an instructor?
Six things worth knowing first
- Does biaX place trades?
- No. The broker connection is read-only and biaX never sends an order. It reads closed positions so you do not have to type them in.
- Do I need a broker connection at all?
- No. Free and Basic work entirely on trades you enter by hand. The connection is what Pro adds, and it is a convenience rather than a different set of statistics.
- What does the Pro trial require?
- A card. It runs fourteen days and converts to a paid subscription unless you cancel before it ends.
- Where do I cancel?
- In your App Store or Google Play subscription settings, or in the biaX app. Deleting the app does not cancel billing, and access continues to the end of the period you have paid for. See the refund and subscription policy.
- Which markets are covered?
- US equities, Korean equities and crypto. Free covers one of the three, Basic covers all three, and Pro applies no limit.
- Is there a version I can use in a browser?
- my.biax.app uses the same account as the app. It is also where a student opens the invite link an instructor sends.
Billing
Both paid plans are bought inside the app, through your App Store or Google Play account. Figures on this page are in US dollars; the stores charge in your own currency, so the amount on your receipt will differ, and they show it before you confirm.
Billing is monthly. The Pro trial requires a card and converts to a paid subscription unless it is cancelled before the fourteen days end. Cancel in your store's subscription settings or in the app — deleting the app does not cancel billing. Details in the refund and subscription policy. Educator plans are arranged directly and are not billed through either store.
Before you buy anything
There is a demo that needs no account. It runs the same computation in your browser, on a constructed sample tape or on rows you paste in yourself, and nothing you paste leaves the tab. It is a more useful thing to read than this page.
Everything biaX reports describes trades that have already closed. It is not a recommendation, a rating of your trades, or a forecast, and the broker connection is read-only in both directions of that sentence. See the terms, the privacy policy, and the support FAQ.
