Modern copy trading platforms use lot size scaling as their most vital feature. The feature enables traders to make automatic trade volume adjustments that depend on their account size, risk tolerance, and broker requirements. Combiz users benefit from lot size scaling because it maintains trade balance and control while helping them achieve their specific trading objectives.
This guide explains the definition and operational mechanism of lot size scaling because it serves as a fundamental component for achieving successful and lasting outcomes in copy trading.
Lot size scaling in copy trading automatically modifies the trade volume copied from a master trader to a follower’s account. The system uses intelligent position adjustment instead of copying the exact lot size because it makes automatic adjustments based on:
The system enables small accounts to manage their risk, while large accounts can implement their successful trading methods through strategic growth.
Lot size scaling maintains risk equilibrium for all followers through its operational method of maintaining risk distribution.
Most professional copy trading software, including Combiz, supports multiple scaling modes. The three most commonly used methods are presented below.
Proportional (Equity-Based) Scaling
This is the most popular and safest method.
The copier calculates lot size using the ratio between the master trader’s equity and the follower’s equity.
Example:
If the master has $10,000 and opens a 1.0 lot trade, a follower with $1,000 may automatically open a 0.1 lot trade.
Best for:
This method keeps drawdown and exposure proportional for every account.
Multiplier / Scale Factor
Here, followers apply a custom multiplier (such as 0.5x, 1x, or 2x) to the master trader’s lot size.
This gives traders flexibility to increase or reduce exposure without changing account balance.
Best for:
Fixed Lot Size
With a fixed lot size, every copied trade opens at a predefined volume, regardless of the master’s trade size or account equity.
Example:
Always open 0.05 lots on every trade.
Best for:
Proper lot size scaling is essential for long-term success. Here’s why:
Risk Management
It is necessary to explain how the process of scaling affects capital protection, which maintains balance between risk and actual account value.
Broker Compatibility
Different brokers define lot sizes differently. Scaling normalizes these differences, ensuring copied trades execute correctly across platforms.
Performance Optimization
Followers can increase lot size on profitable strategies and reduce exposure during volatile markets—helping maximize returns while minimizing losses.
Leverage Control
Traders can use lot size scaling to achieve exact control over their leverage, which enables them to either increase their earnings or decrease their losses based on current market conditions.
For most users, automatic equity-based scaling is strongly recommended.
