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 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:
Symbol-specific configuration (if the traded symbol is listed in the feature's symbols configuration) - highest priority.
Global values inside the feature (used when no symbol-specific entry matches).
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.
