Arbitrage trading is a powerful method for capturing profits from price discrepancies across different markets, all while maintaining minimal risk. With the right tools and strategies, traders can take advantage of market inefficiencies in a systematic and efficient way. This guide explores the fundamentals of arbitrage, how to use advanced trading platforms to execute these strategies, and practical steps to maximize success—especially in digital asset markets.
What Is Arbitrage?
Arbitrage refers to the practice of simultaneously buying and selling an asset across different markets or instruments to profit from price imbalances. These opportunities arise due to temporary supply-demand mismatches, latency in price updates, or differences in trading volumes. The goal is to lock in risk-free or low-risk profits as prices converge.
There are several common types of arbitrage in cryptocurrency trading:
1.1 Funding Rate Arbitrage
Funding rate arbitrage involves opening opposite positions in the spot and perpetual futures markets. Traders hold a long position in one market and a short in the other, effectively hedging market risk. Profits come from collecting positive funding rates paid by traders on the opposing side of the perpetual contract. This strategy can generate consistent returns when funding rates are favorable—especially during bullish sentiment when longs dominate.

1.2 Spot-Futures Arbitrage (Term Arbitrage)
This strategy exploits price differences between the spot market and a futures contract (either quarterly or bi-weekly). When the futures price trades at a significant premium or discount to the spot price, traders can buy the undervalued asset and sell the overvalued one. Once the price gap narrows—typically as the contract approaches expiration—the positions are closed for a profit.
For example, if BTC is trading at $60,000 in the spot market but $62,000 in the futures market, a trader could buy BTC spot and short the futures contract. As expiration nears and prices converge, they close both positions to capture the $2,000 difference.
1.3 Inter-Contract Arbitrage (Calendar Spread)
Also known as inter-delivery or time spread arbitrage, this method involves taking offsetting positions in two futures contracts of the same asset but with different expiration dates. For instance, going long on the March BTC futures contract while shorting the June contract.
Unlike spot-futures arbitrage, there's no guaranteed convergence since both contracts may drift further apart depending on market expectations. Therefore, this strategy carries slightly higher risk but can offer substantial returns during periods of volatile term structure shifts.
What Is OKX’s Arbitrage Order Strategy?
Executing arbitrage manually requires constant monitoring of multiple markets, split-second timing, and precision to avoid slippage. Even a small delay can erase potential profits.
To solve this challenge, OKX offers an integrated arbitrage order strategy tool designed to streamline the process. This feature allows users to place two correlated trades simultaneously—across spot and derivatives markets—with synchronized execution logic. It reduces human error, improves fill rates, and enhances overall efficiency.
The tool automatically calculates pricing relationships, displays real-time spreads, and enables conditional execution settings so traders can focus on strategy rather than micromanagement.
How to Use the Arbitrage Order Strategy (Web Version)
3.1 Interface Overview
The arbitrage trading interface on OKX is divided into four key sections:
- Top Panel: Displays selected arbitrage pair information and current spread.
- Left Side – Order Panel: Where you input trade parameters for both legs of the arbitrage.
- Middle – Market Depth Chart: Shows real-time bid/ask liquidity for accurate decision-making.
- Right Side – K-Line Chart: Visualizes price trends and historical spread behavior.
This layout ensures traders have all necessary data within view, enabling faster and more informed decisions.
3.2 Selecting an Arbitrage Pair
The platform provides pre-calculated arbitrage combinations based on current market conditions. Users can browse available pairs (e.g., BTC/USDT spot vs. BTCUSD perpetual) and select one that meets their criteria—such as spread size, funding rate yield, or volatility profile.
Once selected, both instruments are automatically loaded into the order panel with directional guidance (e.g., buy spot / sell futures).
3.3 Placing Orders
After selecting a pair, users choose pricing methods for each leg:
- Limit Price: Set your own price.
- Market Price: Immediate execution at best available rate.
- Counterparty Price: Targets the best opposing order (bid/ask).
- Premium Price (Take Liquidity): Slightly improves execution speed by stepping into the order book.
- Queue Price (Provide Liquidity): Places orders deeper in the book to potentially get better prices.
You can also enable smart features like:
- Same Quantity / Same Value: Automatically matches volume or notional amount across both legs.
- Auto-Cancel & Re-quote: If one leg fills and the other lags, the unfilled order adjusts dynamically.
- One-Leg Fill Triggers Market Execution on Second Leg: Ensures full hedge completion even under fast-moving markets.
👉 Start using smart arbitrage tools that reduce slippage and boost accuracy.
3.4 Monitoring and Managing Orders
After submission, all active arbitrage strategies appear in the Strategy Orders tab. Here you can track fill status, average prices, realized PnL, and cancel or modify open orders.
Each individual leg is also visible in your regular spot or futures Open Orders list, allowing granular control if needed.
3.5 Position Management and Profit Realization
Once both legs are filled, you hold a hedged position. For funding rate arbitrage, earnings accrue every 8 hours when funding is exchanged. For spot-futures or inter-contract trades, profit is realized only when you close both sides after the spread narrows.
Timing matters: exiting too early leaves money on the table; waiting too long risks reversal.
3.6 Closing the Arbitrage Trade
To complete the cycle, reverse the initial trades:
- If you bought spot BTC and shorted futures, now sell spot BTC and buy back the futures.
- Use the same arbitrage interface for precise execution.
- Monitor spread convergence using real-time analytics.
A successful close locks in profit—ideally exceeding transaction costs and funding fees.
Frequently Asked Questions
Q: Is arbitrage trading completely risk-free?
A: While arbitrage aims to minimize market exposure, risks include execution delays, exchange downtime, liquidity gaps, and sudden changes in funding rates. Proper risk management is essential.
Q: Can I use arbitrage strategies during high-volatility periods?
A: High volatility often widens spreads—creating more opportunity—but also increases slippage risk. Using limit orders and auto-hedging tools helps maintain control.
Q: How often are funding rates paid on perpetual contracts?
A: On OKX, funding occurs every 8 hours (at 04:00, 12:00, and 20:00 UTC). Positive rates mean longs pay shorts; negative means shorts pay longs.
Q: Do I need large capital to profit from arbitrage?
A: Not necessarily. Even small spreads can yield solid returns with leverage and frequent execution. However, larger capital increases absolute profit potential per trade.
Q: Can I automate arbitrage strategies?
A: While full automation requires API access, OKX’s built-in tools offer semi-automated execution with smart triggers and conditional logic—ideal for retail traders.
