Something broken, frozen or plainly wrong? Tell us where and when — with the page or market and the time in UTC, we can usually reproduce it the same day.

suggest a feature →Your subscription is self-service: sign in on /account and use “manage subscription” to change card, cancel or download invoices. Anything the portal can’t do, write us.

How do I install the extension?
The Chrome extension (v4.0.2) is finished and under review at the Chrome Web Store — the install link isn’t public until Google approves it. Subscribers get access the day it lands, and the record it is graded on is already public on /performance.
How do I activate Pro?
Subscribe on /pricing, then sign in inside the extension with the same account. Pro metrics are computed and served by our server, so the upgrade follows your account, not your browser.
Why can a number in the panel differ from this site?
The panel prices live — the model probability moves every second with spot, volatility and time left. /performance archives values frozen at fixed marks each night (t60, for instance). Same model, different timestamps. The full methodology is on /extension.
How do refunds work?
You can cancel anytime from /account — access runs to the end of the paid period. Refund terms are in the Terms; for any billing case, use the billing address above and we’ll sort it out.
Where can I see the track record?
On /performance — every night the collector paper-trades all windows and publishes Brier scores, calibration and P&L with 95% confidence intervals, controls included. Bad nights are published exactly like good ones.
Is Mispria financial advice?
No. Mispria is a data-analytics tool: it measures how a documented model compares with market prices, and publishes the result. It makes no recommendations and is for users aged 18 and over.
