### Locking & Unlocking Trading Sessions

Trading sessions allow you to control access to your Defined account and limit risk of unauthorized trades.

At the top of the trading panel, you can check your current session length by hovering your cursor over the lock icon. In this example, we have 4 days left before trading is locked, requiring Passkey re-authorization.

If you see a lock with no time ![](/files/61HpGtuUy8257X2jWzYY)you must unlock trading with your Passkey to continue. If you select the drop-down selection next to the lock icon, you will be able to choose your preferred time-limit for trading.&#x20;

{% hint style="info" %}
Choose from 15min, 1hr, 4hrs, 1d, 7d, and 30d. Your choice will become your default for the next time you unlock a trading session. You can lock and unlock trading at any time to ensure the security of your account.
{% endhint %}

### Presets

Select the "Trade Settings" icon from the top right of the trading panel 👉<img src="/files/abEPtmFvhQvYuezbWpzF" alt="" data-size="original">

Opening the  "Buy Amount Presets" will show you this panel:

Here you can edit the default ETH, SOL, etc. values shown on the trading panel for quick access to pre-set buy amounts. You can make any of these amounts the default value by selecting the star next to your preferred amount.

Additionally, you can toggle whether or not to require a confirmation when hitting "Buy", as well as enabling confetti graphics on trades.

### Slippage & Gas

By default, slippage will be automatically calculated for you (recommended). You can find this setting in the trading panel under the estimated amount of tokens to receive.

You can use custom slippage by clicking just below the wallet selector where it shows the price per token. Then uncheck auto slippage and enter your preferred slippage.

From here you can also change your gas fee (Network fee) from low, to medium, high, or custom. Just be aware of the added costs if gas fees are high.

{% hint style="success" %}
All EVM transactions are sent with a private RPC and are anti-MEV. This protects users from sandwich attacks and will get you the best available price. Solana transactions have MEV protection off by default.
{% endhint %}

A higher slippage and gas fee may help secure tokens with high volume and volatile price action, but lowers the minimum amount of tokens you're willing to receive. A lower slippage may cause failed transactions if set too low. Remember to account for token taxes when determining preferred slippage.

### Transaction Speed Boost (Solana)

For trading on Solana, users have the option of two priority fee options on the trading panel:

<figure><img src="/files/NtSLmSv6m4wcKLkA5tWd" alt="" width="328"><figcaption><p>Choose from Low or High, as well as MEV protection</p></figcaption></figure>

**Low priority** transactions may take \~10 seconds, but will be the cheapest option. Use this for charts that are not volatile and don't require quick transaction speeds.

**High priority** transactions will complete in \~3 seconds making it the ideal choice for highly volatile charts where speed is crucial and a higher fee is worthwhile.

**MEV Protection** is also an option right below the priority fee selector on Solana. Your transaction will cost a little more and be a bit slower, but you will be protected against MEV attacks.
