Perpetual contracts have become one of the most popular tools for cryptocurrency traders seeking to maximize their market exposure with limited capital. This guide will walk you through everything you need to know about BTC long and short trading, focusing on perpetual contracts using a leading platform as an example—without naming specific competitors. You’ll learn core mechanics, risk management strategies, and step-by-step execution tips to help you trade confidently in 2025 and beyond.
Whether you're new to leveraged trading or looking to refine your strategy, this tutorial delivers practical insights that align with real-world market dynamics.
What Are Perpetual Contracts?
Perpetual contracts are a type of derivative product that allows traders to speculate on the price movement of assets like Bitcoin (BTC) or Ethereum (ETH) without owning the underlying asset. Unlike traditional futures, they have no expiration date, meaning positions can be held indefinitely until manually closed or liquidated.
This makes them ideal for both short-term scalpers and longer-term directional traders.
Key Features of Perpetual Contracts
- No Expiry Date: Positions remain open until you decide to close them or are automatically liquidated due to insufficient margin.
- Funding Rate Mechanism: To keep contract prices aligned with the spot market, periodic payments (funding rates) are exchanged between long and short holders. If the rate is positive, longs pay shorts; if negative, shorts pay longs.
- Leverage Trading: Traders can control large positions with relatively small amounts of capital. For example, 10x leverage means $10 controls $100 worth of BTC.
- Initial and Maintenance Margin: A percentage of your position value must be deposited upfront (initial margin), and you must maintain a minimum balance (maintenance margin) to avoid liquidation.

Understanding Long vs. Short in Crypto Trading
At its core, trading perpetual contracts revolves around two simple actions: going long or going short.
Let’s break it down with a clear example.
Going Long (Bullish Bet)
Imagine you believe Bitcoin’s price will rise. With $100 and 10x leverage, you control a $1,000 position.
- Entry price: $60,000 per BTC
- You buy the equivalent of ~0.0167 BTC ($1,000 / $60,000)
- Price rises 10% → New price: $66,000
- Exit value: 0.0167 × $66,000 = $1,102.20
- Profit: ~$102.20 (over 100% return on your initial $100)
Your gains are amplified by leverage—but so are your losses.
Going Short (Bearish Bet)
Now suppose you expect a price drop. Using the same $100 and 10x leverage:
- You "sell" 0.0167 BTC at $60,000
- Price drops 10% → New price: $54,000
- Buy back 0.0167 BTC at $54,000 = $901.80
- Profit: $1,000 - $901.80 = $98.20 (~98% return)
In shorting, you profit when prices fall—perfect for bear markets or corrections.
⚠️ Important: Leverage magnifies both profits and risks. A 10% move against a 10x leveraged position wipes out your entire investment.
Step-by-Step: How to Trade Perpetual Contracts
While platforms vary slightly in interface, the core process remains consistent across major exchanges. Here’s how to execute a trade effectively.
Step 1: Select the Right Trading Pair
Search for the BTC/USDT or ETH/USDT perpetual contract—these are the most liquid pairs and ideal for beginners. Always ensure you're in the derivatives or contract section, not spot trading.
Step 2: Analyze Market Data
Before entering any trade, review key metrics:
- Current mark price
- Funding rate (positive/negative?)
- Open interest trends
- Liquidation levels heatmap
These indicators help assess market sentiment and potential volatility.
Step 3: Configure Your Position Settings
Once in the trading interface, configure these critical fields:
Isolated vs. Cross Margin
- Cross Margin: Uses your entire account balance as collateral. Offers higher effective leverage but increases liquidation risk.
- Isolated Margin: Limits risk to a defined amount. Safer for new traders.

Set Leverage
Adjust leverage based on your risk tolerance. While 20x or even 100x may seem tempting, lower leverage (5x–10x) improves survival during sharp moves.
Price & Quantity
Enter your desired entry price:
- Market order: Executes immediately at current price.
- Limit order: Waits for your specified price—better for precision.
Quantity depends on available margin. Most platforms show max allowable size based on current leverage and balance.
Managing Risk: Avoiding Liquidation
One of the biggest dangers in perpetual trading is liquidation—when losses exceed your margin, and the system closes your position at a loss.
What Is Estimated Liquidation Price?
This is the price level at which your position gets forcibly closed. It’s not just based on your entry and margin—it also factors in fees and funding costs.
For example:
- You short ETH at $3,083 with 20x leverage
- Maintenance margin: $20
- Estimated liquidation price: $3,267.95
Even though math suggests breaking even at ~$3,283, fees reduce your buffer—hence the earlier liquidation point.
Why Market Close Orders Are Risky
Using “Market Close” or “Close Position” buttons during high volatility often results in poor fill prices and higher fees. Instead:
- Use limit orders to exit at desired levels
- Pre-set take-profit and stop-loss orders
- Avoid panic selling at emotional lows
Frequently Asked Questions (FAQ)
Q: Can I lose more than my initial investment in perpetual contracts?
A: No—if you use isolated margin correctly, your maximum loss is limited to the allocated margin. However, in rare cases like extreme slippage or cross-margin misuse, losses could approach total equity.
Q: What happens when funding rate is positive?
A: Long position holders pay short holders. If you’re long, you’ll see small periodic deductions from your balance. This encourages balance between buying and selling pressure.
Q: How do I calculate profit/loss on a trade?
A:
Profit = (Exit Price – Entry Price) × Position Size
For shorts: Reverse the order → (Entry Price – Exit Price) × Size
Include trading fees and funding payments for accuracy.
Q: Should I use high leverage to increase profits?
A: Not necessarily. High leverage increases liquidation risk dramatically. Many professional traders use 2x–5x leverage for better control and longevity.
Q: What timeframes work best for perpetual trading?
A: Day traders often focus on 5-minute to 4-hour charts. Swing traders may hold positions for days using daily candles. Match your timeframe to your strategy and availability.
Final Tips for Successful Contract Trading
