When trading contracts on perpvia, you can choose different margin modes based on your risk preference. The mode you select determines how your account balance supports your positions, how much funds you may lose during liquidation, and whether the risks of multiple positions affect each other. This article will help you understand the differences between these two margin modes, as well as the "Multi-Position" and "Dual-Position" sub-modes under perpvia’s cross margin mode.

What is Isolated Margin Mode
Isolated margin means that each position has an independent margin that is "isolated" from other funds in the account. If that position is liquidated, you will lose at most the margin allocated to that position, and other balances in the account will not be affected.
In perpvia’s isolated margin mode:
- Supports dual-sided positions. You can hold both long and short positions simultaneously on the same trading pair; their risks are independent and settled separately.
- Risk exposure is controllable. Maximum loss per position = the margin assigned to that position, without dragging down other funds in the account.
- Leverage can be set individually. Each position’s leverage can be adjusted independently without affecting other positions.
Example: You have 1,000 USDT in your account and use isolated margin mode with 10x leverage to open a BTCUSDT long position with 100 USDT margin. Even if the market sharply reverses and this position is liquidated, you will lose at most 100 USDT, and the remaining 900 USDT will remain safe and available.
Who is this suitable for:
- Contract beginners who want strict control over individual position risk
- Exploratory positions or operations with uncertain outcomes
- High-leverage short-term trading
- Users who want to evaluate profit and loss independently for different positions
What is Cross Margin Mode
Cross margin means all available balances in the account jointly serve as margin, supporting all positions under the same margin account. If a position incurs unrealized losses, it will consume the entire available balance of the account; as long as the overall net value is sufficient, a single position will not be immediately liquidated.
In perpvia’s cross margin mode:
- Margin pool is shared. All positions share the account balance, resulting in higher capital utilization.
- Liquidation conditions are stricter but triggered later. Liquidation happens only when the overall net value of the account is insufficient to maintain the margin requirements of all positions.
- Risk scope is larger. Once liquidation occurs, the balance of the settlement currency in the account may be completely lost.
Example: You have 1,000 USDT in your contract account and open a BTCUSDT long position using cross margin mode. If the market moves sharply against you and triggers liquidation, you could lose all USDT balances in that account (balances in other currency accounts are unaffected).
Who is this suitable for:
- Experienced traders who can manage overall account risk
- Users holding multiple related or hedging positions who want unified margin management
- Users pursuing capital efficiency and wanting a deeper "safety cushion" for their positions
Under Cross Margin Mode: Multi-Position Mode vs Dual-Position Mode
When choosing "Cross Margin," perpvia also offers two sub-modes: Multi-Position Mode and Dual-Position Mode.
**Important Note: These two modes differ only in how positions are displayed; they do not affect risk calculations, margin usage, or liquidation price of the positions themselves.** You can freely choose based on your chart viewing and management preferences.
Multi-Position Mode
Each new position is displayed as an independent position in the position list and is not merged with other positions in the same direction.
For example, you first open a 0.1 BTC long position at 60,000 USDT, then add another 0.1 BTC long position at 62,000 USDT. In multi-position mode, the position list will show two separate long position entries:
| Position | Direction | Quantity | Average Entry Price |
|---|---|---|---|
| Position #1 | Long | 0.1 BTC | 60,000 |
| Position #2 | Long | 0.1 BTC | 62,000 |
Suitable for: Traders who prefer to track profit and loss by batch or entry point; users who build positions in stages and want to clearly see each cost and P&L separately.
Dual-Position Mode
Multiple openings in the same direction are automatically merged into one position record, with the average entry price calculated by weighted average.
Using the previous example, in dual-position mode, the position list will show one merged long position:
| Position | Direction | Quantity | Average Entry Price |
|---|---|---|---|
| Long | Long | 0.2 BTC | 61,000 (weighted average price) |
Suitable for: Users who want a clean position list and to see a total cost/total P&L; traders who prefer a "macro position management" approach.
Again, no matter if you choose multi-position or dual-position, the actual risk exposure, margin usage, and liquidation price of the position are the same; the difference is only in how you "see" the positions displayed.
Overview: How to Choose
| Dimension | Isolated Margin | Cross Margin |
|---|---|---|
| Margin Source | Only the margin allocated to that position | Entire available balance in the account |
| Maximum Loss | Limited to the margin of that position | May be the entire balance of that currency in the account |
| Capital Utilization | Lower | Higher |
| Liquidation Trigger | Single position reaches liquidation price | Overall net value falls below maintenance margin |
| Dual-Sided Positions | Supported, long and short risks independent | Depends on Multi-Position / Dual-Position sub-mode |
| Suitable For | Beginners, strict risk controllers | Advanced users, hedgers |
To put it simply:
- If you want to sleep soundly, use isolated margin first. Your risk is locked in a small box, so you know the worst-case scenario.
- If you want to manage your account as a whole, use cross margin. Provided you understand your total position risk and can intervene timely when necessary.
How to Switch Margin Modes
- Go to the perpvia contract trading page and select the contract you want to trade (e.g., BTCUSDT perpetual).
- At the top of the trading panel on the right, find the current margin mode button (displayed as "Isolated" or "Cross").
- Click the button to open the "Position Mode" window.
- Select the mode you want:
- Isolated: directly select "Isolated".
- Cross: after selecting, choose either "Multi-Position Mode" or "Dual-Position Mode".
- Click Confirm to complete the switch.
Can You Switch Modes While Holding Positions?
No. Because cross margin and isolated margin have completely different margin calculation logic and liquidation trigger conditions, switching modes may cause position risk parameters to change instantly, leading to unexpected liquidation. To protect your funds, perpvia restricts switching margin modes under the following conditions:
- There are open positions on the current trading pair
- There are unfilled orders on the current trading pair (including limit orders, take profit/stop loss orders, planned orders, etc.)
If you need to switch, please complete the following two steps first:
- Cancel all unfilled orders for that trading pair
- Close all positions for that trading pair
After confirming the trading pair is in a "no positions, no pending orders" state, you can switch in the position mode window.
Tip: Margin mode is set on a "trading pair" basis. That is, switching the mode for BTCUSDT will not affect the mode for ETHUSDT.
