How to Calculate Bitget CFD Copy Trading Lot Size?

In Bitget CFD copy trading, lot size directly determines your position size, exposure, and profit/loss performance. Many users wonder: How is the CFD copy trading lot size calculated? Why does the copy trading lot size differ? What does the lot multiplier for copy trading mean? What does the maximum lot size per order mean? What does 1:1 copy trading mean? This article will answer these questions in detail.

1. How is the CFD copy trading lot size calculated?

Bitget CFD copy trading currently supports two main modes: fixed-ratio copy trading and fixed-lot copy trading.

Fixed-ratio copy trading (default/most common)

The system automatically calculates your opening lot size based on the equity ratio between your account and the elite trader's account:

Copy trading lot size ≈ Elite trader's opening lot size × (your account equity ÷ elite trader's account equity)

• Account equity includes unrealized PnL.

• The calculated result is rounded down based on the minimum order lot size and minimum volume step for the instrument.

• If the calculated value is below the minimum opening lot size for that instrument, the order may fail to open.

Example:

The elite trader's account equity is 10,000 USDT, and they open 0.5 lots of gold. Your account equity is 2000 USDT (a ratio of 20%), so your copy trading lot size ≈ 0.5 × 0.2 = 0.1 lots.

Fixed-lot copy trading

Regardless of how many lots the elite trader opens, you open positions at your own preset fixed lot size (for example, always 0.01 lots or 0.1 lots), unaffected by the equity ratio between the two accounts. This suits users who want strict control over risk per trade.

2. Why does the copy trading lot size differ?

It is normal for the actual copy trading lot size to differ from the elite trader's lot size. The main reasons include:

Different equity ratios: In fixed-ratio mode, the system scales the lot size based on the equity ratio between the two accounts. If your funds are smaller than the trader's, your lot size will naturally be smaller.

Rounding to the minimum lot step: The calculated result is rounded down to the minimum step allowed for the instrument, causing minor differences.

Real-time price and equity fluctuations: Changes in equity (including floating gains and losses) and market prices at the moment of opening a position can cause the actual lot size to deviate from the estimated value.

Risk parameter limits: If the maximum lot size per order is enabled, or if your account has insufficient available margin, the system will execute based on the cap or the actual lot size available.

Mode differences: In fixed-lot mode, the lot size you set is completely independent of the elite trader's lot size.

Position sizes may differ because the system calculates proportionally based on the account equity of the copier and the elite trader, while also being affected by minimum lot requirements, rounding to the volume step, and real-time price fluctuations.

3. What does the lot multiplier for copy trading mean?

The lot multiplier is an advanced parameter available in fixed-ratio mode, supporting a positive integer range of 1–10.

• If left blank, the system calculates the lot size based on the equity ratio by default.

• Once set, the calculation logic becomes: Copy trading lot size = lot multiplier × elite trader's opening lot size.

This removes the dynamic influence of the equity ratio between the two accounts, making the lot size more stable and closer to the elite trader's actual position size.

Example: The elite trader opens 0.01 lots of XAUUSD. If you set the multiplier to 2, you will open 0.02 lots.

Use cases: when you need precise long/short lot symmetry (such as for hedging strategies), want to reduce lot size differences caused by equity fluctuations, or want to follow more precisely when your account funds are close to the trader's.

4. What does the maximum lot size per order mean?

The maximum lot size per order is a risk control parameter in fixed-ratio mode, typically ranging from 0.01–100 and supporting two decimal places.

It is the safety cap you set for each copy trade order. Even if the lot size calculated by the ratio or multiplier is larger, the system will only open a position up to the maximum lot size you set.

Example: The equity ratio calculation results in 5 lots, but you set the maximum lot size per order to 2 lots, so only 2 lots will actually be opened.

We strongly recommend setting this parameter, especially when your account equity is much higher than the elite trader's, as it effectively prevents oversized single positions and uncontrolled risk.

5. What does 1:1 copy trading mean?

1:1 copy trading refers to maintaining a 1:1 correspondence between your copy trading lot size and the elite trader's opening lot size.

In fixed-ratio mode, setting the lot multiplier to 1 achieves a near 1:1 follow:

• Copy trading lot size = 1 × elite trader's opening lot size

• It is no longer affected by dynamic changes in the equity ratio between the two accounts, making the lot size more stable and symmetrical.

This differs from the default "scaling by equity ratio" approach. The default mode adjusts the lot size as your account funds change, while 1:1 (multiplier = 1) directly replicates the elite trader's opening lot size (after rounding to the minimum step). This suits users who want their position size to closely match the elite trader's and who need long/short symmetry.

Note: Even when set to 1:1, minor differences may still occur due to rounding to the minimum lot step, insufficient margin, or the maximum lot size per order limit.

Practical tips

• Beginners should prioritize fixed-ratio copy trading and set a reasonable lot multiplier and maximum lot size per order as dual safeguards.

• Users with smaller funds or lower risk appetite may consider fixed-lot mode to strictly control exposure per trade.

• Make sure to understand the minimum lot size, step, and leverage requirements for each instrument to avoid copy trade failures caused by lot size limits.

• Combine with independent TP/SL (set by amount, minimum 10 USDT) to further manage risk.

• Regularly check your copy trading records and margin ratio, and adjust parameters based on market conditions.

By understanding the above correctly, you can control your positions and risk more precisely, making Bitget CFD copy trading a truly effective tool for your needs.
