Simulated market data
A sandbox for testing algorithmic trading strategies
Contango is a small personal side-project: a fake exchange feed you can point a trading bot at without any risk of touching real money or real markets. Made-up tickers, a live WebSocket feed, and nothing else.
This is not a real exchange. Every ticker, price and company
name on this site is fictitious. There is no real market data, no brokerage
integration, and no way to place a real trade here — it only exists so you
(or I) can practice wiring up strategy code against a live-ish feed.
What's actually here
- Fictitious tickers A handful of made-up assets, each following its own small random walk — no resemblance to real stocks or crypto intended.
-
Live WebSocket feed
