# Approve Settings > Exclusive to EVM-Compatible Chains Pressing the ⚙️ _Approve_ button reveals the menu shown below: ![Global Settings: Approve Settings](/images/docs/sniper/Approve%20Settings.jpg) We explain the available options below: ### 🟢 | 🔴 **Auto Approve** In order to sell tokens, you NEED to send a suitable approval transaction beforehand. When _Auto Approve_ is enabled 🟢, the bot will immediately and automatically send an _Approve_ transaction after a successful buy, which allows you to sell whenever you want to from that point onwards. If disabled 🔴, you’ll have to _Approve_ manually after you buy. Enabling _Auto Approve_ makes the bot easier to use overall, and is basically required for people who wish to benefit from _Auto Sell_. ### **Gas Price/Delta** This allows you to control the transaction priority of your _Approve_ on **BSC** with _Gas Price_, and on every other EVM-compatible chain with _Gas Delta_. You don’t need to use high values for this, especially if you have _Auto Approve_ enabled. Some final words on _Global Settings_: * **You can configure the **_**Gas Price**_** (BSC) and **_**Gas Delta**_** (every other EVM-compatible chain) for **_**Buys**, **Sells**, and **Approves**_ separately. * **It is important to note that if there are taxes on the token you auto-buy, then you will start with a loss. For example, if the buy tax is 15%, then you will start with a loss of -15% immediately when the buy happens. If your stop loss order is very strict, you might trigger an immediate auto-sell, so be careful.** * **When using custom slippage on EVM-compatible chains, ensure that your slippage is at least equal to the token's buy tax, otherwise, your transaction will fail. This applies to both manual and automated buys, but does not hold for auto-snipes where your slippage can be lower than that of the token's buy tax.** * **These settings are global and affect the behavior of Signals and Copytrade, but you can override them by adjusting the settings in dedicated Signals and Copytrade settings. This is described later in Sections** [**5**](/docs/sniper/signals) **and** [**8**](/docs/sniper/copytrade)**.**
