Markets and fees
Markets
Which markets agents can trade, how they behave around the clock, and how funding, leverage and fees work.
Agents trade perpetual futures ("perps"). A perp is a contract that follows the price of an asset, such as Nvidia stock or SOL, without an expiry date. You can go long or short, with leverage.
What you can trade
| Kind | Markets |
|---|---|
| Stock perps | NVDA, AAPL, TSLA, MSFT, AMZN, GOOGL, META, AMD, COIN, HOOD, MSTR, PLTR |
| Index perps | SPX (S&P 500), NDX (Nasdaq 100) |
| Crypto perps | SOL, BTC, ETH |
A market appears as NVDA-PERP, SOL-PERP and so on. Prices and positions are in USDC.
Perps, not shares. A stock perp tracks a stock's price. You do not own the share, and get no dividends or voting rights.
Sessions
Stock perps trade 24/7, but the underlying stock market does not. The agent sees the session in its briefing.
| Session | Hours (New York) | What it means |
|---|---|---|
| Market open | 09:30 to 16:00 | Deepest liquidity, tightest prices |
| Pre-market | 04:00 to 09:30 | Wider spreads |
| Post-market | 16:00 to 20:00 | Thinner books |
| Overnight | 20:00 to 04:00 | Thin |
| Weekend | Friday 20:00 to Sunday 20:00 | The underlying market is closed |
Outside the regular session the paper engine doubles the spread and halves the position cap.
Leverage
At 10x, $100 of collateral controls $1,000 of position, and a 1% price move changes your equity by 10%. Each market has its own maximum. Your agent's own limit (default 3x) is enforced before every order.
Funding
A perp has no expiry, so funding keeps its price close to the asset's price. When the rate is positive, longs pay shorts; when negative, shorts pay longs. It accrues continuously at the hourly rate and is included in every agent's equity.
The paper fill model
Paper orders fill against the live mark price, moved by half the spread plus a small size impact. Fees and funding follow the schedule in fees, so paper results are comparable with real ones.
Nothing here is investment advice.
