# Market Start and End

Defining a market's time window

## Market Start

This allows one to set up the bond market in advance for review and not have the auction initialize.

* Market Start can only take a value in the future
* Time value displayed is in your local time. The dApp will convert this value into its UTC equivalent time at the contract level.

{% hint style="info" %}
Leave Market Start blank for the bond market to start immediately upon deployment
{% endhint %}

{% hint style="warning" %}
The value cannot be deleted if you change your mind to have the bond market start immediately. You will need to select RESET to re-setup the bond market.
{% endhint %}

* **How to reset**
