### Button Reference Guide

| **Button**                     | **Description**                                                         | **Example & Details**                                                                                                                       |
| ------------------------------ | ----------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- |
| **Buy/Sell Anti-MEV**          | Sends private transactions instead of using the public mempool.         | Turning this **ON (green)** hides your trade from bots to prevent MEV (sandwich) attacks — but transactions may take slightly longer.       |
| **Buy/Sell Anti-MEV + Public** | Protects against MEV attacks **while keeping trades visible on-chain.** | Provides an extra layer of protection with minimal transparency loss. May slightly slow execution speed.                                    |
| **Buy/Sell MEV-Tip**           | Adds a **priority tip** to speed up private Anti-MEV transactions.      | The tip adds to your gas fee. If you leave it unchanged, SpeedyTurtle will use your **default tip** setting.                                |
| **Buy/Sell Gas**               | Sets the **gas price** you’re willing to pay for trades.                | If left blank, your **default gas** value will be used. Increasing gas may improve transaction success during congestion.                   |
| **Buy/Sell Slippage**          | Defines the **maximum price change** you’re willing to accept (0–99%).  | Setting 100% means **unlimited slippage** — risky, but ensures execution.                                                                   |
| **Buy/Sell Tax Limit**         | Blocks tokens with taxes higher than your set limit.                    | Example: You set a 10% limit. If the target buys a token with 15% tax, your copy trade will **not execute.**                                |
| **Buy Only Once**              | Restricts each token purchase to a **single buy per 7 days.**           | Once you buy a token via copy trade, it’s **blocked for 7 days** to prevent repeated entries.                                               |
| **Spending Limit**             | Sets the **maximum total spend**allowed per wallet.                     | You set a 3 SOL limit for Wallet X. You’ve already used 2.5 SOL. Target wallet buys another 1 SOL — your copy trade fails (limit exceeded). |
| **Min Market Cap**             | Sets the **minimum market cap**allowed for auto-buys.                   | Limit: $500,000 → If target buys a token with $400,000 cap, your copy trade won’t execute.                                                  |
| **Max Market Cap**             | Sets the **maximum market cap**allowed for auto-buys.                   | Limit: $500,000 → If target buys a token with $600,000 cap, your copy trade won’t execute.                                                  |

> 💡 **Pro Tip:** Combine *Spending Limit* and *Tax Limit* with *Min/Max Market Cap* filters to keep your copy trades safe from low-liquidity, high-tax, or scam tokens.
