# Accessing Stratium

Stratium operates two trading interfaces on Hyperliquid mainnet.

### Perpetuals: [trade.stratium.xyz](http://trade.stratium.xyz)

Trade perpetual futures through Stratium's Builder Code.

Your existing Hyperliquid USDC balance works across all markets. Same orderbook, same matching engine, same margin system as native Hyperliquid perps.

### Binary Options: [markets.stratium.xyz](http://markets.stratium.xyz)

Trade binary options through HIP-4.

HIP-4 markets are fully collateralized outcome contracts denominated in USDC. Positions settle to 0 or 1 at expiry. Zero fees to open positions. No leverage. No liquidation.

The interface includes a real-time orderbook, price charts, position and P\&L tracking, and a leaderboard.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.stratium.xyz/about-stratium/accessing-stratium.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
