## Migration Sniper

Buy the instant a token **migrates** off its launch platform (Pump.fun, Dynamic Bonding Curve, Launch Labs, etc.) — or **auto‑sell** if you’re already holding. Use this when teams push to Raydium/CLMM or another pool and you want first fills or a clean exit.

### How it works

* **Buy on migrate**: Watches the target token’s migration event; as soon as the new pool/pair is active, places your configured buy on the platforms you allow (Raydium, Pump.fun/Swap, Meteora).
* **Sell on migrate**: If you already hold the token, instantly sells your position when migration is detected.

***

### Setup — Step by step

1. **Token contract address**\
   Paste the token’s **CA**. This is mandatory so the bot knows which migration to track.
2. **Task name**\
   Give the task a short, clear label (e.g., `MIGR-CA_short`).
3. **Wallet**\
   Pick the wallet used for this task.
4. **Platforms**\
   Tick which market place is relavent to the coin you are sniping: **Raydium**, **Pumpfun**, **Meteora**.
5. **Behaviour toggles**
   * **Don’t sell** — Prevents the bot from selling (use only if you want *buy only* behavior).
   * **Buy Once** — Enters on the **first** eligible migration trigger only. Good for avoiding multiple entries.
   * **Use Filtered API** — Uses a filtered feed to reduce false signals.

***

### Use cases

* **First fill on Raydium**: Capture the earliest available pool liquidity after a Pump.fun or DBC launch migrates.
* **De‑risk on migrate**: Exit pre‑migration bags instantly if you don’t want to ride the new pool.

### Field reference

| Field                               | What it does                                    |
| ----------------------------------- | ----------------------------------------------- |
| **Token contract address**          | The CA the bot tracks for migration. Mandatory. |
| **Task name**                       | Friendly label for this sniper.                 |
| **Wallet**                          | Wallet used for buys/sells.                     |
| **Don’t sell**                      | Disable selling entirely for this task.         |
| **Buy Once**                        | Only act on the first migration trigger.        |
| **Use Filtered API**                | Reduces noisy/invalid migration signals.        |
| **Buy Raydium / Pumpfun / Meteora** | Allowed venues for execution post‑migration.    |

> The **Sell on Migrate** behavior can also be configured in your **Exit Strategy**. If this Sniper is *sell‑only*, enable **Don’t sell** off and set **Sell on Migrate** in Exit Strategy.
