</Frame>

## Buy

<Steps>
  <Step title="Open an event">
    Click an event card on [Predict](/guides/predict/overview). The page shows each outcome's probability, your holdings ("You hold 315.71 Yes…") and a **Buy Yes / Buy No** button per outcome.
  </Step>

  <Step title="Pick the outcome and side">
    Click **Buy Yes** or **Buy No** on an outcome, or choose the **Market** and **YES / NO** in the trade panel.
  </Step>

  <Step title="Enter the amount">
    Enter how much CASH to spend, or use the % chips. Your CASH balance is shown under the field.
  </Step>

  <Step title="Check More details">
    **Avg price** (cents per share), **Shares** you'll get, **Pays if right** (shares × \$1) and **Profit if right**. The **Earns while you wait** box shows how much of this position will be paired and its estimated yield.
  </Step>

  <Step title="Buy and sign">
    Click **Buy Yes** / **Buy No** and approve. Your shares go straight into Vanna's pool in the same approval.
  </Step>
</Steps>

## Bet slip

On events with more than one tradable outcome, switch the panel from **One outcome** to **Bet slip** to buy several outcomes at once. Add legs with **Add an outcome**; the slip shows each leg, the total cost and what you get if each pick is right. The bet slip is for buying only.

## Sell

Switch the panel to **Sell**, pick the outcome and side you hold, and enter how many shares to sell. You can also use **Sell** on a position row under the event. Shares in your wallet are sold first; if you hold fewer than you're selling, the rest are redeemed from your pool shares in the same transaction. Shares sell at the current bid.

## Your positions on the event

</Frame>

Each position shows **Avg / now** price, what's **Earning in pool**, and what it **Pays if right**, with **Buy more** and **Sell**. Below, the tabs are:

| Tab | Shows |
| - | - |
| **Earning** | Pairs earning in Vanna's USDC pool, how much of each side is paired or waiting, and what Yes and No earn |
| **Prices** | Price history once it's recorded |
| **Rules** | How the market resolves and its data source |
| **Activity** | Recent trades |

## When the event resolves

Winning shares pay $1 each, losing shares $0. Anything earned in the pool while you waited is already part of your position (see [Earn While You Wait](/guides/predict/earn-while-you-wait)).
