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

Limit Order / Limit TP & SL Order

After full execution

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:

Follower Lots=Follower MarginLeader Margin×Leader Lots\text{Follower Lots} = \frac{\text{Follower Margin}}{\text{Leader Margin}} \times \text{Leader Lots}Follower Lots=Leader MarginFollower Margin​×Leader Lots
  • With Custom Leverage:

Follower Lots=Follower MarginLeader Margin×Leader Lots×Follower LeverageLeader Leverage\text{Follower Lots} = \frac{\text{Follower Margin}}{\text{Leader Margin}} \times \text{Leader Lots} \times \frac{\text{Follower Leverage}}{\text{Leader Leverage}}Follower Lots=Leader MarginFollower Margin​×Leader Lots×Leader LeverageFollower Leverage​
  • Closing Position Formula:

Follower Close Qty=Leader Close QtyLeader Position Size×Follower Position Size\text{Follower Close Qty} = \frac{\text{Leader Close Qty}}{\text{Leader Position Size}} \times \text{Follower Position Size}Follower Close Qty=Leader Position SizeLeader Close Qty​×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.
