Dear Users,
As the demand for customizing the copy ratio is increasing among copiers, BingX has designed the Per Order - Proportional mode for Perpetual Futures Copy Trading and will release the feature on 2023-08-10 (UTC+8). Copiers will be able to decide the margin of copied orders on a Per Order basis by setting up the multiplier in the Proportional mode. Make sure you check it out!

### 1. What is Per Order - Proportional mode?

The Per Order - Proportional mode is an approach in Copy Trading that allows copiers to determine the open value of each copied order by specifying a multiplier (open value refers to the value of a position when it's opened). By doing so, copiers can gain better control over their position value in Copy Trading. Please note that this mode differs from the Per Order - Fixed mode only in terms of how the margin is calculated.

How is margin calculated in the Proportional mode?
1.1 Calculation of the trader's open value per order
Trader's Open Value = Open Price * Open Amount

1.2 Calculation of the copier's open value per order
Copier's Open Value = Trader's Open Value * Copier's Multiplier

1.3 Calculation of the margin required for the copier to open a copy order
Copier's Margin = Copier's Open Value / Copier's Leverage
Note: The leverage represents the current leverage set by the copier in Perpetual Futures.

1.4 The order amount is determined based on the copier's margin calculated above
Open Long: Multiplier * Trader's Open Value * (1 - Taker Fee Rate * Leverage) / Max {Trader's Filled Price * (1 + Slippage Protection Ratio), Trader's Filled Price}
Open Short: Multiplier * Trader's Open Value * (1 - Taker Fee Rate * Leverage) / Max {Trader's Filled Price * (1 - Slippage Protection Ratio), Trader's Filled Price}

Note: The order amount only needs to be calculated when opening a position by the system. When closing a position, the closing amount equals the opening amount.

### 2. How to copy a trade in the Per Order - Proportional mode?

Step 2: On the "Copy Trading" page, you'll find "All Traders". From there, click the filter icon and select "BingX Perpetual Futures".
Note: Detailed live trading data spanning up to 180 days is provided, enabling copiers to make well-informed decisions about traders.
Step 4: Click "Copy" and proceed with the necessary settings.
• Select the Per Order - Proportional mode and set a multiplier within the default range of 0.01 to 10.
• Alternatively, you can use the recommended multiplier.
• Click "Copy Now" and ensure that your Perpetual Futures account has sufficient funds to copy at least one trade.

### 3. How to set the multiplier based on different risk appetites?

Settings of the Multiplier:
The multiplier in the Proportional mode ranges from 0.01 to 10 by default. As indicated by the formula "Copier's Open Value = Trader's Open Value * Copier's Multiplier", the copier's open value is determined by the trader's open value, and the multiplier determines whether the copier's open value is magnified or reduced in relation to the trader's open value. Essentially, the higher your risk appetite, the higher the multiplier you can set.

3.1 Recommended multiplier
Recommended Multiplier = Modifier * (Copier's Perpetual Futures Account Equity / Trader's Perpetual Futures Account Equity)
Modifier for minimum recommended multiplier = 0.5
Modifier for maximum recommended multiplier = 1

Example:
Let's assume the copier's Perpetual Futures account equity is 10,000 USDT and the trader's Perpetual Futures account equity is 20,000 USDT.
In this case, the maximum recommended multiplier will be 10,000 / 20,000 * 1 = 0.5, and the minimum recommended multiplier will be 0.5 * 0.5 = 0.25. Based on these calculations, the recommended multiplier displayed on the page will range from 0.25 to 0.5.
Note: The recommended multiplier is calculated based on the ratio of the copier's account equity to the trader's account equity. If the recommended multiplier is set to the highest level, the copier's open value will match that of the trader (only for that specific trader).

3.2. How to set the multiplier as a copier with a low risk appetite?
If you choose a trader who is conservative (taking Jennie as an example), particularly someone with substantial account equity but a low open value, you can use the maximum recommended multiplier. By doing so, you can aim to achieve similar profits as the trader.

On the other hand, if the selected trader is someone who is willing to take high risks for potentially high profits, you can set a multiplier of less than 1 or use the minimum recommended multiplier. This helps reduce the open value per order for lower risk exposure.

3.3. How to set the multiplier as a copier with a high risk appetite?
If you have a high risk appetite as a copier, you can set a multiplier greater than 1 (similar to utilizing leverage).

Risk Warning: Please set your Copy Trading parameters based on your risk tolerance and the recommended multiplier to avoid losing more than you can afford.
