Futures Copy Trading Rules

Futures Copy Trading enables users to replicate the trading activities of experienced traders in real-time automatically. This guide outlines how copy trading works, how positions are opened and closed, how quantities are calculated, and reasons why copying might fail.

⚙️ Supported Contract Types

• USDT-margined contracts

• Coin-margined contracts

🧾 Order Copying Logic

Opening Positions

Leader's Order Type	Trigger Method	Follower's Copy Order
Market Order / Market TP & SL Order	Immediate	Market order
IOC Limit Order (with max price deviation)	Immediate after execution	Limit order with calculated deviation
Limit Order / Limit TP & SL Order	After full execution	Same type as leader’s order

Closing Positions

Leader's Order Type	Trigger Method	Follower's Copy Order
Market Order / Market TP & SL Order	Immediate	Market order
Limit Order / Limit TP & SL Order	After full execution	Market order

Note: Copy trades follow the same fee structure as regular contract trades, calculated in either USDT or the base coin, depending on the contract type.

📐 Copy Quantity Calculation

1. Fixed Ratio Copying

• OpeningPosition Formula:

$$\text{Follower Lots} = \frac{\text{Follower Margin}}{\text{Leader Margin}} \times \text{Leader Lots}$$

• With Custom Leverage:

$$\text{Follower Lots} = \frac{\text{Follower Margin}}{\text{Leader Margin}} \times \text{Leader Lots} \times \frac{\text{Follower Leverage}}{\text{Leader Leverage}}$$

• Closing Position Formula:

$$\text{Follower Close Qty} = \frac{\text{Leader Close Qty}}{\text{Leader Position Size}} \times \text{Follower Position Size}$$

• If not a whole number, round up to the nearest whole number.

Example: If a leader closes 0.2 BTC out of a 1 BTC position (20%), the follower closes 20% of their position.

2. Fixed Amount Copying

• Each order uses a fixed amount of margin.

  • Example: If set to $20 per order with a total cap of $60, the user can open up to 3 positions.

• Closing Formula: Same as in fixed ratio mode (percentage-based).

🔄 Reverse Positions

• If a lead trader closes a position and opens a reverse position, the follower’s system will:

  1. Close the current position

  2. Open a new position in the opposite direction

🚫 Copy Order Failure: Possible Reasons

Reason
Insufficient available margin in follower’s copy trading project
Leader used a limit/IOC order that was not fully executed
Partial fills on IOC orders — system does not copy partially filled IOC trades
Market slippage exceeds max deviation threshold
Order size is below the platform’s minimum or above the maximum
Follower’s margin mode conflicts with the leader’s
Exceeded maximum number of positions or open orders allowed
Position exceeds leverage-based maximum allowed size

❗ Why Is My Copied Order Smaller Than Expected?

• The order was a partial fill of an IOC limit order from the leader.

• This results in smaller-than-expected quantities for the follower, especially in fixed-amount or fixed-ratio modes.

✅ Best Practices for Followers

• Ensure a sufficient margin is always available.

• Monitor your copy project regularly, especially in fixed amount mode, where the leader's actions can increase your risk.

• Keep track of the leader’s leverage and margin mode to avoid copy failure.

• Use stable margin and position limits to maintain sync with the lead trader.
