# Multi Legs

The **Multi Legs** widgets let you trade two instruments as one order: buy one leg and sell the other, executed together. They come as a pair, a form and a chart, and make up the **Multi legs** layout together with an orders table for multi-leg orders, which appears only in that layout.

Multi-leg trading is enabled per account. If it is not enabled for yours, the **Multi Legs form** is not listed in the layout menu and the **Multi Legs** tab of the [Orders table](order-table.md) is hidden.

## Multi Legs form

The form is titled **Multi Legs (beta)**. You can have **one** on the page.

Each leg has its own row:

- Row **1** is the leading leg and row **2** the lagging leg (hover the number to see which). Each row has the symbol, the **Account** and the live price.
- The **side** of the leading leg (**BUY** or **SELL**). The lagging leg always takes the opposite side.
- A **Trading style** per leg. You type the **Quantity** of the leading leg; the lagging leg's quantity is calculated from it.

Both legs must share the same quote currency; otherwise the form shows *Quote currency must be the same in both trading pairs*. The arrows icon next to the leading leg's side swaps the two symbols.

Below the legs:

- **Strategy**: **TWAP** or **Iceberg**.
- **Duration** (TWAP).
- **Clip size** type and value.
- **Mis-Hedge Tolerance**, set in % or in the quote currency.

**Clear** resets the form and **Submit order** sends it. As with the order form, **Show order review** in the widget **⋮** menu (layout unlocked) turns the button into **Review order**, which opens a summary to confirm first.

Running multi-leg orders are listed in the **Multi Legs** tab of the Orders table; finished ones offer a **Reverse** action in History. See [Managing Orders](../../reference/managing-orders.md).

## Multi Legs chart

The **Multi Legs chart** shows the price chart of the leading leg with a spread indicator against the lagging leg, in basis points. It appears once both legs are set in the Multi Legs form. You can have **one** on the page.
