How to start trading on Astros

1. Create an account

1. Open the Astros perp trading site and click Connect Wallet, then select the wallet you use and complete the connection. The tutorial describes no sign-up or KYC step beyond connecting a wallet. source ↗
2. Astros perp runs on the Sui network, with orders aggregated off-chain and settled on-chain. source ↗

2. Deposit collateral

1. Go to Account, then Deposit, and choose the currency and amount. Currently only USDC is accepted, and you confirm the transaction in your wallet. source ↗
2. Deposited USDC is converted to USD at a 1:1 ratio, and your total balance shows under Account. If you have no USDC on Sui, the docs suggest bridging USDC from another chain or swapping other assets for USDC. source ↗

3. Open your first position

1. Open a position by choosing Buy/Long or Sell/Short, using leverage. Order types are Market (fills immediately and may slip) and Limit (fills at your price or better, or not at all). source ↗
2. Isolated margin is the default mode and cross margin is also available. You can use only one margin mode per trading pair, and to switch you must first close or cancel all positions and orders on that pair. source ↗
3. You can pre-set stop loss and take profit prices. They are processed as market orders when triggered, so they may slip. source ↗
4. Maker orders pay 0.02% and taker orders pay 0.04% of position value. source ↗

4. Know how liquidation works

1. Liquidation uses the mark price and happens when a position's margin balance falls to or below maintenance margin. Maintenance margin rates differ by token pair, so check them before trading. source ↗
2. In isolated mode a liquidation only costs the margin of that position. In cross mode you can lose all allocated collateral, margin reserved for open orders and your whole available balance. source ↗
3. Mark price is the index price plus a 30-minute moving average of the premium. The index combines Coinbase, Binance and OKX prices with the Pyth oracle. source ↗
4. If the insurance fund cannot cover a liquidation loss, auto-deleveraging reduces opposite positions, starting with the most profitable and most leveraged ones. source ↗

5. Withdraw

1. Go to Account, then Withdraw, choose the currency and amount and confirm in your wallet. USD is converted back to USDC at 1:1 and arrives in your wallet once confirmed. source ↗
2. Margin tied up in open orders or positions cannot be withdrawn. If a withdrawal times out or your wallet rejects it, the funds are frozen for 10 minutes before you can retry. source ↗

6. Common mistakes

1. Funding is charged every hour, with a cap of 0.75% per hour. Longs pay shorts when the contract trades above spot and shorts pay longs when it trades below. source ↗
2. Right after a trade, unrealized PnL can look positive or negative because your fill price differs from the mark price. Watch your liquidation price rather than the short-term PnL figure. source ↗
3. Initial margin on an isolated position cannot be reduced, although you can add margin to it. source ↗

Before you trade

Perpetual futures use leverage: a small price move against you can liquidate your collateral. Start with a small amount and low leverage, and read the venue’s current fee and margin pages, which can change after this guide was checked.
