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.

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:
With Custom Leverage:
Closing Position Formula:
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:
Close the current position
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.
