After copying a portfolio, the system will automatically duplicate the trades executed by the lead traders for the copy traders.
Lead traders can use BNB to pay trading fees by transferring BNB to their portfolio, and enjoy a fee discount when using BNB to pay. Futures copy trading only supports USDT contracts, so all fees will be calculated in USDT.
How to calculate the open and close position size?
[Fixed Ratio] mode
Open position:
For basic copy amount ratio: The copy trader's opening order cost is proportional to the lead trader’s order cost. However, the copy trader’s position entry price may not be exactly the same as the lead trader’s. Please note that slippage can affect the copy trader’s position size and the final position might be lower than the lead trader’s. For example, the lead trader’s available margin balance is 1,000 USDT and they opened a position with an order cost of 500 USDT (The amount ratio is 50%). If a copy trader uses 500 USDT to copy the portfolio, the system will use 250 USDT as the open cost to open the position. However, please note that the final order size may be lower than 250 USDT due to slippage.
For ‘Copy then Open’ position amount ratio (copying only positions where market price is more favorable), the ratio would be the position initial margin/margin balance. For example, the lead trader’s current position has an initial margin of 500 USDT, and the margin balance is 1,000 USDT, the amount ratio would be 50%. If copy trader copied the portfolio with 100 USDT, system will use 50 USDT as the order cost to open the position.
Close position: For example, a lead trader has a 1 BTCUSDT position and partially closed 20% of their position (0.2 BTC). One of their copy traders copied the trade with a total investment amount of 0.6 BTC, the system will automatically close 20% (0.12 BTC) for the copy trader.
[Fixed Amount] mode
Open position: The system will open each trade using the cost per order amount the copy trader set.
For example, a copy trader sets the cost per order amount as 20 USDT and the total investment amount is 60 USDT. The system will copy each new trade with 20 USDT as the open cost. After copying 3 orders, their margin balance will become 0 (lower than the cost per order amount). Therefore, the copy trader won’t be able to copy the lead trader’s positions anymore as they don’t have a sufficient margin balance.
Close position: For example, a lead trader has a 1 BTCUSDT position and partially closed 20% of their position (0.2 BTC). One of their copy traders copied the trade with a total investment amount of 0.6 BTC, the system will automatically close 20% (0.12 BTC) for the copy trader.
Please note:
If the open position amount doesn’t meet the minimum trade amount, the system will open the position using the minimum trade amount. For more details, please refer to Trading Rules.
If the open position amount exceeds the maximum allowable amount for the chosen leverage level, the system will open the position using the maximum allowable amount. For more details, please refer to Leverage and Margin of USDⓈ-M Futures.
Opposite positions/offset
Lead traders may open opposite positions to limit the losses/gains.
When a lead trader closes an open position and opens an opposite position at the same time, the system will only close the position for copy traders - no new position will be opened.
Why did copy trading fail?
Copy trading might fail as a result of any of the following scenarios:
The available margin balance in the copy portfolio is insufficient;
When the lead trader uses a limit or stop-limit order to open the position, but the order hasn't been fully filled;
When the market slippage exceeds the limit;
When the lead trader opens an opposite position (please refer to the description under “Opposite positions/offset”).
The position notional value is below the symbol’s minimum notional value.
Note: When a copy portfolio’s margin balance is below the minimum copy amount and fails to copy 5 consecutive orders, it will be automatically closed. Reasons for the failure could be insufficient margin, not meeting the minimum order size, etc. The system will check and close copy portfolios that don’t meet the requirements each Friday.
Why is the final position size smaller than the cost per order amount/fixed ratio amount?
This might happen as a result of any of the following scenarios:
When the IOC limit order was partially filled;
In the [Fixed Amount] mode: When the available margin balance is below the cost per order amount, the system will use the remaining balance to create the order;
Due to slippage, some copy traders may not be able to copy an order, the system will therefore check the dynamic maximum size for each symbol. If the number of copy traders exceeds the limit, the system will reallocate the copy trading amount of all copy traders, which may cause the final position size to be smaller than the expected;
When the lead trader increases the leverage and open position at the same time. Since copying is instant, the leverage might have increased after opening the position for copiers, this may lead to the position being smaller;
When the position value exceeds the max notional value for the leverage tier. The system will open the position with the max notional value;
When the copy ratio is near 100% of the margin balance, the system will use 90% to calculate the ratio. This is to avoid copy failure in the event of a margin check failure due to open loss.
Why is the final position size larger than the cost per order amount/fixed ratio amount?
This might happen as a result of any of the following scenarios:
When the final size calculated based on the fixed ratio/fixed amount is smaller than the minimum trade amount or minimum notional value, the system will open the order with the minimum order amount or minimum notional value;
When the lead trader reduces leverage and open position at the same time. Since copying is instant, the leverage might have reduced after opening the position for copiers, this may lead to the position being larger.
