# Price impact

Price impact is a **pre-trade analytical tool** that outlines the market-impact risk of each transaction. It estimates the price impact of a transaction by **monitoring the volume participation rate and orderbook depth**.

!!! tip "Now optional"
    Since 30 September 2026 the same analysis appears directly in the order form, in the [pre-trade tile](order-form.md#pre-trade-tile). You no longer need this widget to size an order; keep it if you like the fuller figure grid on screen, or remove it to free space.

## What it shows

The widget reads the symbol, side, quantity and duration from the order form of its group:

- **Your trade**, with the share it represents of the order book (**Trade Qty % OrderBook**) and of traded volume (**Trade Qty % of Volume**), colour-coded by risk.
- **Last Price**, **Est. Sweep price** (the projected price for your size, from an order-book snapshot with a 50% adjustment for potential spoofing) and **Est. Slippage**.
- **% of 24H Vol**, a **volatility index** with short-term and mid-term volatility, **24h High** / **24h Low**, **1min Vol** and **24h Vol**, and open interest on futures.

You can have up to **4** Price impact widgets on the page. A Price impact widget must belong to a [group](../widgets-workspace.md#change-your-layout); it is part of the **Advanced** layout.
