# Multiplier

With the multiplier feature, you can fine-tune the multiplier for each symbol. When you activate it, you need to define a global multiplier (which overrides the copier settings). After that, you can add specific symbols and configure their settings as desired.

## Settings

The feature exposes the same lot-sizing knobs as the copier itself, so it can fully replace them for the affected trades:

* **Multiplier**: Global multiplier applied to the calculated slave lot size.
* **Scale by**: Scale type used for lot sizing. See [Copiers](/features/basic-features/copiers.md#scale-by) in the copier settings for a description of each option (**Balance**, **Equity**, **Fixed lot size**, **No scaling**).
* **Fixed lot size**: Lot size used when **Scale by** is set to **Fixed lot size**.
* **Fix master balance/equity**: Overrides the master account balance/equity used in the lot-size calculation. A value of 0 means deactivated (the real value is used).
* **Fix slave balance/equity**: Overrides the slave account balance/equity used in the lot-size calculation. A value of 0 means deactivated (the real value is used).
* **Symbols configuration**: Optional per-symbol overrides. For each configured symbol you can define its own **Multiplier**, **Scale by**, **Fixed lot size**, **Fix master balance/equity** and **Fix slave balance/equity**.

## Override behavior

When the Multiplier feature is added to a copier, its values **replace** the corresponding copier settings for lot-size calculation. The precedence is:

1. **Symbol-specific configuration** (if the traded symbol is listed in the feature's symbols configuration) - highest priority.
2. **Global values inside the feature** (used when no symbol-specific entry matches).
3. **Copier settings** - used only when the feature is not attached to the copier.

Because of this, once the Multiplier feature is active, the **Multiplier**, **Scale by**, **Fixed lot size**, **Fix master balance/equity** and **Fix slave balance/equity** defined on the copier itself are effectively ignored for any trade the feature applies to.

Other copier-level options (Slippage, Max lot size, Max open positions, Copy SL/TP, Reverse, Ignore contract size, Ignore currency, etc.) are **not** touched by this feature. They always come from the copier settings.
