Contract trading offers a powerful way for crypto traders to amplify their strategies using leverage and advanced order types. Whether you're aiming to hedge positions, speculate on price movements, or diversify your portfolio, understanding the mechanics of contract trading is essential. This guide walks you through every step of contract trading on a mobile app interface—covering key concepts like margin modes, order types, risk management, and more—so both beginners and intermediate traders can confidently navigate the process.
Understanding U-Margin vs. Coin-Margin Contracts
The foundation of contract trading lies in choosing the right settlement type. Most platforms offer two primary models:
- U-Margin (USDT-settled) Contracts: These are settled in stablecoins like USDT. This means your profits, losses, and margin are all calculated in USDT, regardless of the underlying asset (e.g., BTC/USDT or ETH/USDT). It simplifies value tracking since you’re dealing with a stable reference point.
- Coin-Margin (Coin-settled) Contracts: These use the base cryptocurrency (like BTC or ETH) as the settlement currency. For example, a BTC/USD contract would require BTC as collateral, and P&L is also denominated in BTC.

In this guide, we’ll focus on U-Margin contracts, which are ideal for beginners due to their predictable valuation and ease of use.
Transferring Funds to Your Contract Account
Before placing any trades, ensure your contract wallet has sufficient funds.
Step-by-Step Fund Transfer
- Open your trading app and go to Assets.
- Tap Transfer.
- Select the transfer direction: from Spot Account to Contract Account.
- Choose the asset—typically USDT for U-Margin trading.
- Enter the amount you wish to transfer.
- Confirm the transfer.
Once completed, your funds will be available for leveraged trading immediately.
How to Place a Contract Trade
Successful contract trading hinges on correctly configuring three core settings before placing an order: position mode, margin mode, and leverage mode.
Setting Position Mode
Your position mode determines how many directional bets you can hold simultaneously on the same trading pair.
- Single-Position Mode: You can only hold one direction—either long or short—for a given pair (e.g., BTC/USDT).
- Dual-Position Mode: Allows holding both long and short positions at the same time.
⚠️ Note: You cannot change the position mode if you have open positions or pending orders.
How to Change Position Mode
- Go to the contract trading screen.
- Tap the More icon (usually three dots).
- Navigate to Preferences > Position Mode.
- Select either Single or Dual.
Configuring Margin Mode
Margin mode defines how your collateral protects your position.
Isolated Margin: Risk is confined to a specific position. Only the allocated margin is at risk—even if other positions fail.
- Example: With $1,000 in your account, allocating $200 as isolated margin means only $200 is exposed per trade.
Cross Margin: Uses your entire available balance in the settlement currency (e.g., USDT) to support a position. Reduces liquidation risk but increases exposure.
- Example: A $200 position under cross-margin could lose up to your full $1,000 balance if market moves sharply against you.
✅ Pro Tip: Isolated margin is safer for new traders; cross margin suits experienced users managing multiple positions.
How to Set Margin Mode
- On the trading page, tap the Isolated/Cross toggle.
- Slide to select your preferred mode.
- Enable Apply to All Contracts if desired.
- Confirm.
Adjusting Leverage Mode
Leverage amplifies both gains and losses. Choose wisely based on your risk tolerance.
- Simple Mode: Applies the same leverage and margin settings to both long and short sides.
- Advanced Mode: Lets you set different leverage levels and margin types for long and short positions independently.
🔒 You cannot change leverage mode while holding active positions or open orders.
How to Switch Leverage Mode
- Tap More > Preferences > Leverage Mode.
- Select Simple or Advanced.
Choosing an Order Type
Modern platforms offer several order execution methods tailored to different strategies.
Limit Order
Best for traders who want precise entry/exit points.
- Set a price below current market price to open a long.
- Set above market price to open a short.
Options for time-in-force:
- GTC (Good Till Cancelled): Stays active until filled or canceled.
- IOC (Immediate or Cancel): Partial fills allowed; unfilled portion cancels instantly.
- FOK (Fill or Kill): Must fill entirely or cancel.

Market Order
Executes instantly at best available price.
- Fastest way to enter a trade.
- May suffer slippage during volatile markets.
- Includes MTL (Market-to-Limit) option: Unfilled portions become limit orders at last executed price.
Stop-Limit / Take-Profit Orders (Plan Orders)
Triggers a limit order when a specified price is reached.
- Useful for automating entries based on breakouts or reversals.
- Define trigger price (based on mark, index, or last price) and execution price.
- Validity options: 24h, 7 days, or permanent.
Trailing Stop Order
Automatically adjusts stop-loss based on price movement.
- Tracks highest high (for longs) or lowest low (over past 10 minutes).
- Helps lock in profits during trending markets without constant monitoring.
Maker-Only Orders
Guarantees your order adds liquidity (doesn't take existing orders).
- Often receives fee rebates.
- Ideal for scalpers and arbitrageurs.
Understanding Maximum Position Size Calculation
Your maximum possible trade size depends on:
- Available margin
- Selected leverage
- Contract value (face value × price)
- Estimated fees
Formula:
Max Contracts = Available Margin / [Entry Price × Face Value × (Initial Margin Rate + 2 × Est. Fee Rate)]This value updates dynamically based on whether you're using limit or market orders:
- Limit Orders: Use your input price.
- Market Orders: Use best bid/ask (sell 1 for longs, buy 1 for shorts).
Quantities are always rounded down to whole numbers.
Monitoring and Managing Open Positions
After placing an order, tracking its status is crucial.
If Order Is Not Triggered
Check under:
- Open Orders
- Order History
Pending stop-limit or conditional orders appear here until activated.
If Order Is Executed
View details in:
- Current Positions
From there, you can:
- Manually close the position (Close Position)
- Adjust leverage or margin
- Set take-profit and stop-loss levels
How to Close a Position
- Go to Positions tab.
- Tap the position you want to exit.
- Choose Close, then confirm size and price type (market or limit).
Auto-Liquidation (Margin Call)
If equity drops below maintenance margin, the system forcibly closes your position to prevent further loss. While designed as a safety net, it should be avoided through proper risk management.

Frequently Asked Questions
Q: What’s the difference between isolated and cross margin?
A: Isolated limits risk to a set amount per trade; cross uses all available funds in that currency, increasing exposure but reducing liquidation risk initially.
Q: Can I change my position mode mid-trade?
A: No. You must close all positions and cancel pending orders first.
Q: Why didn’t my limit order execute?
A: It may not have matched the market price. Ensure your buy order is below or sell order above the current market level.
Q: How does leverage affect my profit?
A: Higher leverage multiplies both gains and losses proportionally. A 10x leveraged trade doubles profit/loss compared to 5x for the same price move.
Q: Are trailing stops effective in sideways markets?
A: Less so—they work best in strong trends. In ranging markets, they may trigger prematurely.
Q: What happens during forced liquidation?
A: The exchange automatically closes your position at prevailing market rates when collateral falls too low, potentially resulting in total loss of margin.
