# How to Trade on PolyFundr

> Place and close simulated YES or NO trades on real Polymarket markets: how prices work, how to enter and exit a position, and how outcomes resolve.

Trading on PolyFundr means placing simulated YES or NO trades on real Polymarket markets. When you submit, your position is recorded at the current Polymarket price, and your shares and PnL are calculated from that snapshot.

## Understanding prices

Prices are shown in cents and represent the market's implied probability:

* **50¢** means a 50% chance the outcome resolves YES; **90¢** means 90%.
* A YES token at 30¢ and its NO token at 70¢ always sum to about 100¢.

<Note>Prices refresh automatically but can lag a move by a few seconds. If one looks stale, reload the event page.</Note>

## Before you trade

<Info>You need an active challenge or funded account to submit trades. If you don't have one, visit `/accounts` to buy a challenge, or try the free demo account to get familiar with the trade panel first.</Info>

## Placing a trade

<Steps>
  <Step title="Open an event">
    From **Markets** (`/markets`), click any event card to open its event page at `/event/[slug]`.
  </Step>

  <Step title="Select an outcome">
    The outcomes table lists every tradable market for the event. Click a row, or the **Yes** / **No** button, to select it and pre-fill the direction.
  </Step>

  <Step title="Choose YES or NO">
    * **YES:** you expect the outcome to resolve YES. Your entry price is the current YES token price.
    * **NO:** you expect it to resolve NO. Your entry price is the current NO token price.
  </Step>

  <Step title="Enter an amount">
    Type a USDC amount in the **Amount (\$)** field, or use the quick-add buttons. The **MAX** button uses the largest amount your challenge rules allow.

    As you type, the panel shows:

    * **Avg. price:** your entry price in cents.
    * **Est. fee:** the fee for this market (often **Free**). See [Fees & execution](/trading/fees).
    * **To win:** your potential gain if the trade resolves at 100¢, after fees.
  </Step>

  <Step title="Submit">
    Click **Trade · \$amount**. The position is recorded immediately at the latest price.
  </Step>
</Steps>

## How shares are calculated

Your shares are your amount divided by the entry price (as a decimal). At 40¢ with \$20 you get 50 shares; if it resolves to 100¢, those shares are worth \$50, a \$30 gain.

<Note>On markets that charge a fee, the fee comes out of your amount first, so you receive slightly fewer shares. Each fill is stored as its own position, with no netting. See [Fees & execution](/trading/fees).</Note>

## Wide spread warning

If the gap between the YES and NO prices is wider than 3¢, the panel warns you. A wide spread can show an immediate paper loss until the market tightens, common on lower-liquidity markets. It is not an error, but check the spread before trading.

## Closing a position

<Steps>
  <Step title="Find your position">
    On the event page or the **Portfolio** page (`/portfolio`), open the **Positions** panel to see your open positions with their current price and PnL.
  </Step>

  <Step title="Close it">
    Click **Close**, then **Sell at market** in the confirmation. The position closes at the latest price. Closing before resolution may include a fee; holding a winner to resolution is free. See [Fees & execution](/trading/fees).
  </Step>
</Steps>

## Resolved and unavailable outcomes

Resolved outcomes appear in a collapsed **Resolved outcomes** section at the bottom of the outcomes table and can't be traded. An outcome under review shows an **In review** badge, and trading is disabled until the review completes.
