Ⅱ. What Are the Rules for Copy Trading?

Fixed ratio

Orders will be opened in proportion to the trader’s fund allocation.

When copying an "Open" order in this mode, the proportion of funds allocated to the copy order will be the same as the trader's.
Opening Ratio = Trader’s Opening Margin / Trader's Available Margin

When copying a "Close" order in this mode, the proportion of the closing amount will be the same as the trader's.
Closing Ratio = (Trader's Closing Position Size) / (Trader's Pre-Closing Position Size)

1. Opening Position

  Copy Order Type Order Size
Copy with Slippage IOC Limit Order

Formulas:
- Opening Ratio = Trader’s Opening Margin / (Available Margin + Pending Order Frozen Margin)

- Copier's Opening Margin = (Copier's Available Margin) × Opening Ratio

- Copier's Opening Amount = Copier's Opening Margin / Order Price / (1/Leverage + Taker Fee Rate)

(Available Margin: Refers to the margin available for opening positions. In Cross Margin Mode = Available Balance + Unrealized PnL; In Isolated Margin Mode = Available Balance)

Note:
- If the opening amount is below the minimum, the system will not place the order, resulting in copy trade failure.

- If the copier's opening value exceeds the maximum allowed, it will be capped at the maximum.
Copy with 0 Slippage 0 Slippage Order
 
Example: If your trader has 2,000 USDT available margin and uses 1,000 USDT to open a position, the opening ratio is 50%. If your available margin is 1,000 USDT, the system will allocate 500 USDT as your margin to copy the trade proportionally.
 

2. Closing Position

  Copy Order Type Order Size
Copy with Slippage Market Order

Formula:
- Closing Ratio = Trader's Closing Position Size / Trader's Pre-Closing Position Size

- Copier's Closing Amount = Copier's Position Size × Closing Ratio

- Copier's Order Size = max (Copier's Closing Amount, Minimum Closing Amount)

Note:
- If the closing amount is below the minimum, the order size will be adjusted to the minimum closing amount.

Closing amount that does not meet the order size precision requirement will be rounded down.
Copy with 0 Slippage 0 Slippage Order
 
Example: If your trader holds 2 BTC and closes 0.4 BTC, the closing ratio is 20%. If you hold 1 BTC, the system will close 20% of your position, equivalent to 0.2 BTC.
 

Fixed amount

Orders will be opened with a fixed amount of margin (margin per order).
 

1. Opening Position

  Copy Order Type Order Size
Copy with Slippage IOC Limit Order

Formula:
- Copier's Order Size = (Copier's Margin per Order) / [Order Price × (1/Leverage + Taker Fee Rate)]

Note:
- If the margin per order is below the minimum, the order will be canceled.
- If the copier's opening position value exceeds the maximum allowed, it will be capped at the maximum.
Copy with 0 Slippage 0 Slippage Order
 
Example: Suppose you set your margin per order of 30 USDT and have 90 USDT Copy Trading Funds. When your trader opens a position, the system will use 30 USDT as margin for each copy trade, allowing up to 3 concurrent trades (30 × 3 = 90 USDT).
 

2. Closing Position

  Copy Order Type Order Size
Copy with Slippage Market Order

Formulas:
- Closing Ratio = Trader’s Closing Amount / Trader's Position Size
- Copier's Closing Amount = Copier's Position Size * Closing Ratio
- Copier's Order Size = max (Copier's Closing Amount, Minimum Closing Amount)

Note:
If the closing amount is below the minimum, the order size will be adjusted to the minimum closing amount.
Copy with 0 Slippage 0 Slippage Order
Example: If your trader holds 2 BTC and closes 0.4 BTC, the closing ratio is 20%. If you hold 1 BTC, the system will close 20% of your position, equivalent to 0.2 BTC.
