# Place Your First Order

> Authenticate with an existing Event Contracts account and place your first order.

This page shows how to place your first order using an existing Event Contracts account. We recommend having at least 10 USDT of available balance.

**1. Complete Authentication**

Prepare your API Key and signature information according to the private API authentication requirements.

**2. Select an Outcome**

Query the Market and choose the Outcome you want to trade from `outcomes[]`. Orders identify the specific outcome using `token_id`.

**3. Place the Order**

Set the price and quantity based on order-book liquidity, then submit the trading request to the order endpoint.

**4. Wait for Settlement**

After an order is matched, the resulting trade may still require asynchronous on-chain settlement. Confirm settlement completion before reading the final asset state.

**5. Check the Position**

Query the position for the corresponding Market and confirm the purchased Outcome Token amount, available quantity, and settlement status.
