The calculation of portfolio margin involves converting multiple asset types into a unified margin value to determine a user's available margin and leverage level. This calculation typically considers each asset's current market value, platform - specific conversion rates (or risk factors), and relevant risk management strategies. Below are the general calculation steps and an example:
Calculation Steps
- Determine Asset Market Value
Calculate the market value of each asset by multiplying the asset quantity by its market price.
- Apply Conversion Rate
Each asset has a specific conversion rate (or risk coefficient) based on its stability and liquidity. This rate typically ranges between 0 and 1, representing the platform's confidence in using the asset as margin.
- Calculate Margin Value of Each Asset
Multiply the market value of each asset by its corresponding conversion rate to obtain its margin value.
- Sum Up Total Margin Value
Add up the margin values of all assets to determine the total margin value of the account.
The platform has set the following conversion rates:
| Asset |
Value Conversion Rate |
|
BTC
|
90% |
| ETH |
80% |
| USDT |
100% |
Example Calculation
Assume a user holds the following assets on a trading platform:
- 2 BTC (Bitcoin), current price: $30,000/BTC
- 10 ETH (Ethereum), current price: $2,000/ETH
- 20,000 USDT (Tether), price: $1/USDT
Calculation Steps:
| Asset |
USD Price |
Value Conversion Rate |
USD Equivalent Amount |
| 2 BTC |
30,000 USD |
90% |
2 BTC * 30,000 USD* 90%=54,000 USD |
| 10 ETH |
2,000 USD |
80% |
10 ETH * 2,000 USD* 80% = 16,000 USD |
| 20,000 USDT |
1 USD |
100% |
20,000 USDT * 1 USD* 100% = 20,000 USD |
|
Total Margin Value:54,000 USD (BTC) + 16,000 USD (ETH) + 20,000 USD (USDT) = 90,000 USD
The total account margin is:90,000 USD
|
Summary
Through this calculation, the user's total margin value is $90,000, which serves as the basis for trading on the platform.
Actual Platform Calculations & Risk Management
In practice, trading platforms may employ more sophisticated margin calculations and risk management strategies, such as:
Dynamic Conversion Rate Adjustments
- Conversion rates may be adjusted based on market volatility and asset risk levels.
Risk Limits & Alert Mechanisms
- Platforms set risk thresholds, triggering warnings or automatic liquidation when margin value falls below these limits.
Portfolio Risk Assessment
- Platforms may evaluate asset correlations and adjust margin requirements based on the overall portfolio risk.
