Understanding Lot Sizing in Copy Trading: How Your Trades Are Calculated

How Lot Sizing Works in Copy Trading

When you copy a signal provider on ReadiTrades, the system doesn't simply mirror the exact same lot size. Instead, it uses proportional scaling to match your account size and risk level.

The Formula

The copied lot size is calculated as:

Copied Lots = Leader Lots × (Your Balance ÷ Leader Balance) × Copy Ratio

Example

• Leader balance: $10,000
• Leader trades: 1.0 lot XAUUSD
• Your balance: $500
• Copy ratio: 1.0x
• Your copied lot: 0.05 lots

This means you're risking the same percentage of your account as the leader, keeping your risk proportional regardless of account size.

Adjusting Your Copy Ratio

From your dashboard, you can adjust the copy ratio to increase or decrease your exposure. A 0.5x ratio halves the position size, while 2.0x doubles it. Use our risk management guide to find the right setting for your goals.

Minimum Lot Sizes

Most brokers enforce a minimum lot size of 0.01. If the proportional calculation results in less than 0.01, the trade may be skipped to prevent errors. This is especially important for smaller accounts - check our starting capital guide for recommendations.
