# Open Book

{% hint style="warning" %}
When setting the fees for your transactions, be aware that every transaction takes all the fee set!
{% endhint %}

* **Start on Detect: type yes** or **no** in order to make the bot start sending transactions as soon as it detects a new opened pool. If set on no you will need to start manually. This is used on **AFK mode**.
* **Use Instant Sell: type yes** or **no** to make the bot instant sell after sniping the coin and use [**Instant Sell** settings](/4bot/settings/instant-sell.md).

* **Transactions to send:** value corresponding to the total number of transactions that will be sent when buying.
* **Transactions Delay in Milliseconds:** range of time that passes among transactions when buying. This setting is ignored when using bundles to buy.
