### Step 2 - Create pricing

Once the data asset is published, user(s) can choose the pricing option as per their choice. Only the publisher can set the pricing option and cannot be changed once the publisher selects any one method.

There are 2 options for settings the price of an asset on Ocean Marketplace.

1. Fixed pricing
2. Dynamic pricing (using Banalcer pools)

#### Create fixed pricing for a data set

Connect to the Ocean Marketplace with the publisher account and go the published asset.

If the pricing is not set Marketplace will provide an option to create a pricing. Click on the create pricing button as shown below.
