# Trading Settings: Slippage, MEV Protection & Primary Tokens

{% embed url="<https://youtu.be/m8zagbHz-e8>" %}

Advanced traders can also access additional settings to customize their trading.&#x20;

To access **Trading Settings**, click on the gear button over the **Execution Panel**. There, you’ll find the following options:

* **Skip preview:** Toggle Off/On to enable or disable trade confirmation previews.
* **Value loss warning:** Set a percentage threshold (e.g., 20%) to receive alerts if a trade incurs excessive slippage. This is particularly important to set up if you turn off confirmation previews.
* **PnL (Profit and Loss) calculation:** Choose between **Position-based** or **All** (aggregated) profit-and-loss tracking. This will decide whether your **PnL** resets after fully closing out a position or whether a statement carries over to future positions.
* **Universal Gas:** Uses **$PARTI** as the default gas token on all your UniversalX transactions.
* **Default Primary Tokens:** Select which tokens (USDC, USDT, SOL, ETH, BTC, BNB) to prioritize for transactions. If you toggle off a token, it will not be used in future transactions or counted in your balance, even if you hold it. (***NOTE: This function is currently unavailable; it will eventually be reinstated.***)
* **Custom buy amounts:** Edit the preset purchase values that are shown in your **Buy** screen.
* **Custom sell percentage:** Edit the preset sale percentages that are shown then selling through the **Execution panel**.
* **Slippage control:** Select **Auto** for dynamic adjustments or **Fixed** to set a custom percentage (e.g., 5%).
* **Anti-MEV Protection (Solana)**: UniversalX offers default protection for EVM trades but, given the way Solana trades work, if you want to reduce the risk of sandwich attacks when trading on Solana, you can turn MEV protection on and off. You can also specify how much you want to pay to validators to prioritize your trade. The more you pay, the higher your protection will be.&#x20;

Once you’ve adjusted your settings, click "**Confirm**" to save and apply changes instantly.
