Opera is an API-first trading challenge. Copy a short-lived token, send orders from your own client, and react to live fills and state. The on-screen ladder is for reading and verifying your code unless Click trading is enabled in Opera Settings.

​
Objective

Complete each mission and collect P&L along the way. Skills targeted: programmatic order entry, token auth and live updates, market making from code. Open Opera from the Simulator hub (or go to /opera).

​
How a session works

  1. Sign in and open Opera. Copy the API token (do not share it; tokens expire quickly).
  2. Connect to wss://www.getavenir.co/ws and authenticate with operaConnect.
  3. Follow the mission panel goals (two-sided quotes, joining a static bot, price constraints, reacting to hits).
  4. Place and cancel via operaPlace / operaCancel / operaCancelAll. Listen for operaResult, operaState, and orderBook.
  5. Advance through missions as each goal is met. On status: 401, copy a fresh token and reconnect.
Starter snippets and full message schemas live in the API Reference.
