# Order Preview: See an Order's Effect Before You Submit

> The order preview shows how an order would change your available balance, equity, position, margin, Greeks, funding and liquidation price before you submit it.

Before you submit, the order form shows an **Order Preview**: each metric as it stands now (**Before**), as it would be once the order fills (**After**), and the **Change**.

## What it shows

| Metric | What it tells you |
| - | - |
| **Available** | The balance left free for new orders and withdrawals |
| **Equity** | Your account value, including unrealized P/L |
| **Position Size** | The size of your position on this market |
| **Position Margin** | The margin held by the position |
| **Net Delta, Gamma, Vega, Theta** | Your option exposure, for perpetual options |
| **24h Funding** | Projected funding over the next 24 hours. Positive means you receive it. |
| **24h Drift** | Projected [drift](https://docs.everstrike.io/trading/drift.md) over the next 24 hours, for perpetual options |
| **Liquidation Price** | Where liquidation would begin after the order |

The form also shows the **expected execution price** and quantity, so you can see slippage before you trade.

## Why it's worth a look

* **Liquidation price.** The single most useful line. If the After value sits close to the current price, the order adds more risk than it looks.
* **24h Funding.** On a crowded market, holding the position may cost more per day than you expect.
* **Available.** Shows how much room the order leaves for other trades.

> [!TIP]
>
> Greeks and drift only apply to perpetual options. For perpetual futures, focus on margin, funding and the liquidation price.

## Estimates, not promises

The After values assume the order fills at the expected price. Market orders can fill at a different average price if the book moves, and funding projections assume the current rate holds for 24 hours, which it usually doesn't.
