</details>

<details>

<summary>What does the price of a Share mean?</summary>

## Trading

<details>

<summary>What are the fees?</summary>

Fees are charged only on Taker orders. The fee rate varies by market — up to $0.12500 per Share on 1-Minute Markets, $0.07500 on 3-Minute Markets, $0.02500 on 5-Minute Markets, $0.01250 on Daily Markets, $0.02500 on Sports Markets, and $0.00625 on Other Markets (all at $0.500); fees are significantly lower for skewed odds. **Maker fees are 0%.** [Fee Details](/market-structure/market-structure/fees.md)

</details>

<details>

<summary>What is the difference between Taker and Maker?</summary>

**Taker** consumes liquidity (fee charged). **Maker** provides liquidity (no fee + Rebate). See [Order Types](/trading/trading/order-types.md) for details.

</details>

<details>

<summary>What is Maker Rebate?</summary>

Makers receive **50% of the Taker fee** as a Rebate, paid automatically upon fill. No claim required. This means Makers pay 0% fees and earn income by providing liquidity.

</details>

<details>

<summary>What is the difference between Market Order and Limit Order?</summary>

**Market Order** executes immediately at the best available price (always Taker, fee charged). **Limit Order** is placed at a price you set — if posted to the orderbook, it becomes a Maker order with 0% fees and Rebate eligibility.

</details>

<details>

<summary>Can I sell my Shares before the market settles?</summary>

Yes. You can sell your position anytime before settlement. If the price has moved in your favor, you can lock in profit without waiting for the final result.

</details>

<details>

<summary>What are Split and Merge?</summary>

**Split** converts 1 trading currency into 1 Yes Share + 1 No Share. **Merge** does the reverse. Both are fee-free. Useful for hedging, arbitrage, and liquidity provision. See [Split & Merge](/trading/trading/split-merge.md) for details.

</details>

<details>

<summary>What happens when a market closes?</summary>

Winning Shares can be redeemed at $1.000 per Share. Losing Shares receive no payout. See [Redeem](/trading/trading/redeem.md) for details.

</details>

<details>

<summary>What happens if a market is cancelled?</summary>

A refund is issued at your **share cost** (price × shares, excluding fees). Previously paid Taker fees are not refunded.

</details>

<details>

<summary>What happens if the outcome is unknown?</summary>

All Shares are settled at $0.500 (50:50 split) regardless of which side you hold.

</details>
