### Trading Settings

You can customize the following Settings for your trades:

1. **Slippage:** You can set a slippage tolerance to protect your trades from value loss. Your transaction will revert if the price changes unfavorably for you by more than your set percentage.
2. **Anti-MEV (Solana):** You can enable MEV protection to reduce the risk of an MEV attack on Solana. When activated, a tip is paid to nodes for enhanced protection. This is recommended for large-value trades. MEV protection is enabled by default on EVM chains.
3. **Default Primary Token(s):** In “Buy” mode, the tokens you select will be used by default to purchase others. If a token is disabled, it won’t be reflected in your balance or used for payments when using this function.
4. **Skip Preview:** When enabled, you’ll be able to execute trades automatically without previewing their information. The system will still provide you with a warning if your trade might result in significant impact (e.g. slippage).
