# Submitting DEX Orders

This page explains how to swap DEX tokens.

**Prerequisite:** You must have funds and the appropriate gas in your trading wallet to submit an order. 

**Important: Your trading wallet needs both the token you want to swap AND the native gas token for that chain.** A common error is depositing only a stablecoin without the required gas token (e.g., ETH for the Ethereum network). Without gas in your trading wallet, **you cannot execute a swap.**  

Refer to the [**DEX Trading Wallet Setup**](/dex-swaps-trading/dex-trading-wallet-setup.md) guide if you have not deposited funds.

### How to Trade: Two Modes

You can trade from two different interfaces depending on your needs.

#### Terminal Mode

Use this mode for a detailed trading view with charts and analytics like transaction volume and trader counts.

1. **Select Your Wallet:** From the main terminal (`app.tread.fi`), select your connected wallet from the accounts drop down.
2. **View DEX Tokens:** The interface will automatically switch to show the DEX token universe.
3. **Find Your Pair:** Click the pair selector (or use `ctrl/cmd +k`) and open the **DEX tab**. This lists all tradable tokens for your connected wallet's chain.

#### Algo Swap Mode

Use this mode for a simplified, fast swap.

1. **Enable Mode:** Toggle on **Algo Swap** in the top right of the interface.
2. **Select DEX Tab:** Navigate to the **DEX Tab**.
3. **Execute Swap:** Select your tokens and submit the order.

### Reviewing Your Order

Before you confirm any trade, you must review the following details. These figures are critical for understanding the final cost and outcome of your trade.

* **Max Slippage:** The highest price change you're willing to tolerate before the trade fails.
* **Estimated Slippage:** A forecast of how much the actual execution price might differ from the quoted price.
* **Estimated Gas Fee:** The approximate network cost to execute the swap on the blockchain.
* **Trading Fee:** A fee charged by the platform for executing your trade, usually deducted from the output amount.
* **Available Gas:** The amount of native gas token (e.g., ETH, SOL) available in your trading wallet to pay for the transaction. Without sufficient gas, the submit order button will be greyed out.&#x20;

Once you have reviewed and accepted these terms, you can confirm and submit your trade.

### Order Details

After submitting a trade, you are directed to the order details page. This page gives you a complete, real-time overview of your transaction's progress and final outcome.

**What this page shows:**

* **Order Summary:** A complete breakdown including the final execution price, transaction status (e.g., `Finished`), duration, and total value.
* **Fees & Slippage:** A clear view of the actual gas fees paid and the final price impact.
* **Placements & Fills:** Detailed logs of your transaction.
  * **Placements:** Shows the outgoing part of your swap, including the amount sent and its status.
  * **Fills:** Shows the incoming part of your swap, confirming the amount you received.
* **Transaction ID:** A direct link to the blockchain explorer for independent verification.
* **Messages:** A log of real-time status updates for your order.

This page provides full transparency, allowing you to track your order from submission to completion and verify all details on-chain.

### Troubleshooting

If a transaction fails, an error message will appear. Common reasons for failure include:

* **Insufficient Funds:** Not enough tokens or gas in your trading wallet.
* **Swapping Your Entire Gas Balance:** Attempting to swap your full balance of a native gas token (like ETH) will fail because no funds are left to pay the required gas fee for the transaction itself.
* **Network Error:** The blockchain is congested or experiencing issues.
* **Slippage Exceeded:** The price changed more than your "Max Slippage" setting before the trade could be completed.
