# Buy when it's fair

> Leave a one-time order that the agent fills the moment the price clears.

When the Guard blocks a buy (for example the premium is above 1% at night), you do not have to come back later.

<Steps>
  <Step title="Start a buy">Enter the amount as usual.</Step>
  <Step title="Choose 'Buy when it's fair'">On the confirm screen, or **Once, when fair** in the plan editor.</Step>
  <Step title="Sign and allow">Sign the one-time plan and allow funding for it.</Step>
</Steps>

The agent checks every 15 minutes for up to **7 days**. The first time the market is open and the price is fair, it buys, writes its reason, and the order is done. If no fair moment comes in 7 days, the order closes as Skipped and nothing is spent.
