#### **Connecting to Ostium -** [**here**](/ostium-docs/ostium-trading-engine/step-by-step-tutorial/connecting-to-ostium.md)

Click **“Connect”** on the app and choose either a Web3 wallet (for advanced users) or email (for beginners). Web3 gives full control, while email provides a simpler, gasless smart account experience.

#### **Fund Wallet/Account -** [**here**](/ostium-docs/ostium-trading-engine/step-by-step-tutorial/fund-wallet-account.md)

Use **Fun.xyz** for seamless deposits. You can send USDC on Arbitrum directly or deposit other tokens, which will be automatically converted and bridged.

#### **Opening a Trade -** [**here**](/ostium-docs/ostium-trading-engine/step-by-step-tutorial/opening-a-trade.md)

Choose a market, fill in trade details (side, order type, amount, leverage), and optionally set Take Profit/Stop Loss. Review the fee breakdown, confirm the trade, and monitor it in real time.

#### **Editing an Opened Trade -** [**here**](/ostium-docs/ostium-trading-engine/step-by-step-tutorial/editing-a-trade.md)

Select your trade to share it, adjust collateral (add/remove), or edit Take Profit/Stop Loss settings to manage your position.

#### **Closing a Trade -** [**here**](/ostium-docs/ostium-trading-engine/closing-trades.md)

Click “Close” on the trade. You can fully or partially close it (just stay above the minimum size). Once closed, view your trade history in the **Portfolio** tab.
