For desks

What a contract is worth, and where it can go.

The free terminal shows the price. Desks get the engine behind it, on screen and over an API.

The engine, as an API.

Live, on the markets above. Desks call the same engine on any contract with their own key.

Not a trader? This one's for you.

Everything above is for people who already know how to read a market. The app is for people who don't yet, and want to trade properly: the same information, laid out so it makes sense.

  • Read the order book in plain words: what people are paying, and how much is waiting at each price
  • See what your trade really means before you place it: what it costs, what it pays, and what has to happen
  • Understand it first, then decide if you still want to make it
  • Zena's own fair value guides you on the price

Questions

What people ask first.

What is Zena?

A terminal for prediction markets. It puts 10 venues on one board, prices their markets with its own engine, and shows the order book, the chart and Zena's fair value beside the price.

Is it free?

Reading is free: the board, any market's page, its book, its chart and its fair value, on the web and on your phone. Trading needs an account. Desks that want every object, alerts and watchlists, and the engine over an API book a demo.

What is the fair value?

The engine's price for the contract, built from the venue's own trading history and its live book, and graded against how markets actually settle. It is a research estimate, and it can be wrong.

Can I trade from Zena?

Yes. Where a venue lets you connect your own account, orders are signed in your browser and go straight to the venue, and every market opens on its own venue in one click.

Is any of this investment advice?

No. Zena is a research and data product. Nothing on it is a recommendation or an offer to buy or sell anything.
