# Lot-sizing modes

The three ways a receiver can size each copied trade — Lotsize Multiplier, Fixed Lotsize, and Fixed % Risk.

Each receiver decides how large its copied trades are, independently of the sender and of other receivers. You pick one of three modes in the receiver's **Trading** tab.

## Lotsize Multiplier (default)

Copies the sender's lot size and multiplies it by a value you set.

The **Suggest** button sets the multiplier so the sender and receiver risk the same proportion of their balances (1:1 risk):

```
Suggested multiplier = Receiver balance / Sender balance
```

**Example** — sender balance $50,000, receiver balance $5,000. Suggest sets the multiplier to 5,000 / 50,000 = **0.10**. If the sender opens 1.00 lot, the receiver opens 0.10 lots.

Suggest uses the balances at the moment you click it. The multiplier then stays fixed: it doesn't follow later changes in either balance, so click **Suggest** again if the balances drift apart.

## Fixed Lotsize

The receiver always opens the **same lot size**, whatever the sender does and whatever the balances are.

**Example** — fixed at 0.20 lots. Whether the sender opens 0.50, 1.00, or 2.00 lots, the receiver opens **0.20 lots** every time.

## Fixed % Risk

The receiver risks a fixed **percentage of its balance** on every trade. Trada calculates the lot size automatically from the stop-loss distance and that percentage.

**Example** — 1% risk, receiver balance $10,000 → $100 at risk. With a 50-pip stop-loss, Trada sizes the lot so the maximum loss is about $100.

{% hint style="warning" %}
Fixed % Risk needs a stop-loss to size against. Make sure the sender sets a stop-loss, or configure one in the receiver's [SL & TP](/copy-trading/configure-receiver/sl-tp-modes.md) settings. Without one, the trade isn't copied — or, if **Force Minimum Lot Size** is on, it's copied at the broker's minimum lot size.
{% endhint %}

## Guarding the result

Two advanced settings (on the **Trading** tab) keep sizing within safe bounds:

* **Max Lot Size** caps the final size after the mode is applied. A computed 3.50 lots with a 2.00 cap is sent as 2.00.
* **Force Minimum Lot Size** raises a calculated size up to the broker's minimum when it would otherwise be too small — useful with Fixed % Risk on a smaller receiver.

See [Add & configure a receiver](/copy-trading/configure-receiver.md) for all advanced settings.
