# Auto Buy

> Automated buying against a token.

Auto Buy places buys for you. Stack one or more strategies on a [token](/trading/token-page) or arm them on a [launch](/launch/launch).

Open **Auto Buy** in the trade sidebar, then **Configure new**. The dialog is **Set up Auto Buy**. Edit later from the gear. The dialog becomes **Edit Auto Buy**.

New strategies save off. Flip **Enable** on the row to run one.

## What triggers a buy

Each strategy is **Replication** or **Timer**.

**Replication** fires when someone else sells at least **Trigger size**. The default trigger is **0.1** of the quote token.

* **Max buy amount** caps one replicated buy. Default **1** quote.
* **Replication ratio** is how much you buy relative to that sell. Default **50%**. At 50%, a 1 quote sell triggers a 0.5 quote buy.
* **Execution chance** is the probability a qualifying sell actually fires. Default **10%**.

**Timer** buys a fixed **Amount** on a **Delay**. Defaults are **0.1** quote every **30** seconds.

## Sizing

Buy amounts are quote token, not a percent of a wallet.

A live row shows **Bought**, **Tokens**, and the wallet count. The mode pill shows the replication percent, the timer delay, or the active range.

## Stop conditions

Open **Advanced settings** for optional gates.

**Active in range** keeps the strategy idle outside a band. Pick **Market cap** or **Price**. Buy defaults are **Min** 50,000 and **Max** 100,000 when you turn the switch on.

**Stop triggers** are optional. Leave a field empty to skip it. The first one hit stops the strategy.

| Field                    | What stops the strategy                                                      |
| ------------------------ | ---------------------------------------------------------------------------- |
| **Native balance below** | A wallet's native balance drops below this floor, so gas is not emptied out. |
| **Token balance below**  | Remaining token holdings drop below this amount.                             |
| **Max spent**            | The strategy has spent this much quote in total.                             |
| **Duration**             | The strategy has been running this many seconds.                             |

A running row shows progress on each stop you set.

## Wallets

**Wallets** limits which addresses may execute the strategy. The picker starts from your token selection, or every attached wallet.

Wallet selection is not saved to [presets](/platform/presets#automation-presets).

Selecting the developer wallet asks **Select developer wallet?**

## Running one

1. Click **Configure new**.
2. Pick **Replication** or **Timer**, set the fields, and choose wallets.
3. Click **Add strategy**.
4. Flip **Enable** on the row.

**Save changes** updates an existing strategy. The bookmark saves an **Auto Buy** preset. **Reuse past preset** adds the strategy off until you enable it.

On launch, the badge is **{n} armed**. On a live token it is **{n} running**.

You can show or hide range bands on the [chart](/trading/token-page#chart) when a strategy has **Active in range** on.
