# Trading Settings

Slippage, fees, MEV, Auto-Buy and presets per chain.

Open ⚙️ **Settings** and pick the chain on the top row. Each chain keeps its own settings.

![Settings](https://953360368-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FvlAJauw5lS9CaoRy1bfd%2Fuploads%2F8c7neoJmT54SgzYRDNoN%2F01-settings-solana-76.jpg?alt=media)

| Setting                                  | What it does                                                                                                                          |
| ---------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- |
| 🎚️ **Slippage**                         | How far the price may move before the trade fails. Buy and sell are set separately.                                                   |
| 💨 **Fees**                              | Solana: fee and tip per transaction. BNB Chain and Robinhood: gas speed.                                                              |
| 🔰 **MEV**                               | Off, Turbo or Secure. Secure hides your trade from bots that trade ahead of it, but is slower. Turbo is fastest, with no protection.  |
| 🟢 **Buy Presets** / 🔴 **Sell Presets** | The buy amounts and sell % buttons on the trade screen.                                                                               |
| 🤖 **Auto-Buy**                          | Buys as soon as you paste a token address.                                                                                            |
| ↩️ **Restore Defaults**                  | Returns this chain's slippage, fees, MEV, Auto-Buy and presets to Click's defaults. Wallets, hidden tokens and account settings stay. |

## Auto-Buy

1. Tap 🤖 **Auto-Buy**.
2. Turn it on (🟢). The switch covers every chain.
3. Set the amount. It is saved for the chain picked on the Settings top row: to set another chain, pick it on the top row and open 🤖 **Auto-Buy** again. A chain with amount 0 does not auto-buy.

![Auto-Buy](https://953360368-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FvlAJauw5lS9CaoRy1bfd%2Fuploads%2FZhCQwPpwDqBTW6E9fNwT%2F06-auto-buy-off-77.jpg?alt=media)

{% hint style="warning" %}
With Auto-Buy on, every token address you paste is a real buy from your preferred wallet, and pasting the same token again buys again. Turn it off before you paste an address just to look. **Restore Defaults** also sets a non-zero Auto-Buy amount for that chain.
