In financial markets, periods of irrational volatility can cause prices to deviate from their typical levels. This creates opportunities for arbitrage capital to step in, helping to restore equilibrium while capturing low-risk profits in the process. Arbitrage order strategies involve monitoring two markets simultaneously, placing coordinated orders, and ensuring near-simultaneous execution to capitalize on either funding rate differences or price spreads.
These strategies are broadly categorized into two types: funding rate arbitrage and spread arbitrage. The latter can be further divided into spot-futures arbitrage and futures-futures arbitrage.
What Is Arbitrage Order Trading?
Arbitrage order trading is a method where a trader executes two offsetting positions across different markets or instruments at nearly the same time. The goal is to profit from small discrepancies in pricing, while minimizing exposure to market movement.
This approach requires precise execution, a clear understanding of market mechanics, and often the use of specialized trading tools.
Types of Arbitrage Strategies
Funding Rate Arbitrage
This strategy involves taking opposite positions in a spot market and its corresponding perpetual swap contract. The positions are of equal size and are designed to offset each other’s price risk. The profit comes from capturing the funding rate paid in the perpetual swap market.
For instance, if you are short a perpetual contract and long the same amount in spot, you can earn the funding fee when the rate is positive, regardless of which direction the market moves.
Spot-Futures Arbitrage (Basis Trading)
When a significant price gap, or "basis," appears between a spot asset and its corresponding futures contract, traders can profit by buying the undervalued instrument and selling the overvalued one. The profit is realized when the gap between the two prices narrows.
This is generally considered a lower-risk arbitrage method because the prices of spot and futures for the same asset tend to converge upon the futures' expiration date.
Futures-Futures Arbitrage (Calendar Spread)
This strategy involves trading two futures contracts of the same asset but with different expiration dates. The trader aims to profit from changes in the price difference, or "spread," between them.
It's important to note that this spread does not necessarily converge to zero, making this a slightly higher-risk strategy compared to spot-futures arbitrage.
How to Execute an Arbitrage Order: A Step-by-Step Example
Executing a successful arbitrage trade requires attention to detail and an understanding of the platform you are using. Here’s a generalized walkthrough using a funding rate arbitrage example with a crypto asset like SOL.
- Navigate to the Strategy Trading Module: Access your trading platform’s advanced tools section, often labeled "Strategy," "Algorithmic Trading," or "Arbitrage."
- Analyze the Funding Rate: Before entering a trade, check the current funding rate for the perpetual contract. A positive rate means long positions pay short positions. This creates an opportunity to receive payments by holding a short perpetual position.
Configure the Arbitrage Order:
- Select the appropriate markets (e.g., SOL perpetual and SOL spot).
- Enter your desired order price and quantity for the perpetual contract leg.
- Crucially, enable the "two-leg order" or "multi-leg execution" feature.
- Select an execution condition like "Market IFD" (Immediate-or-Cancel) or "One-leg fills, market-order the other." This ensures that if one order executes, the platform will immediately attempt to fill the opposing order at the best available market price, minimizing execution risk and slippage.
Monitor and Manage the Position: Once the orders are filled, you will be long the spot asset and short the perpetual contract. Your portfolio will be largely neutral to SOL's price movements. You will now accumulate funding rate payments every funding period.
- To close the position, you must manually sell the spot asset and buy back the perpetual contract short position.

Key Considerations for Successful Arbitrage
- Execution Speed: The markets move quickly. Even a slight delay can erase a potential profit. Using a platform with robust and fast order routing is essential.
- Transaction Costs: Always factor in trading fees, which can significantly impact the profitability of small-price discrepancies.
- Slippage: This is the risk that your order is filled at a worse price than expected. Using limit orders and conditional execution settings helps mitigate this.
- Understanding Risks: While called "risk-free," arbitrage is not without its challenges. Technical errors, sudden market moves causing one leg to fail, or unexpected changes in funding rates can lead to losses.
Frequently Asked Questions
What is the main goal of arbitrage order trading?
The primary goal is to profit from temporary price inefficiencies between two highly correlated markets while maintaining a market-neutral position. This means the profit is designed to come from the convergence of prices or the collection of funding fees, not from speculating on the market's direction.
What is the difference between funding rate and spread arbitrage?
Funding rate arbitrage aims to capture periodic payments made between traders in perpetual swap markets. Spread arbitrage, which includes spot-futures and futures-futures strategies, aims to profit from the narrowing of a price gap between two different instruments.
Is arbitrage trading completely risk-free?
No, it is often described as "low-risk" but not risk-free. Key risks include execution risk (one order filling and the other failing), significant and sudden changes in the price relationship between the two assets (basis risk), and unforeseen transaction costs or platform issues.
Why is a two-leg order execution setting important?
This setting is critical for managing execution risk. It links the two orders, ensuring that the platform automatically submits the second order as soon as the first is filled. This automation is vital for capturing the fleeting arbitrage opportunity before prices change.
Can I use leverage in arbitrage strategies?
While some platforms may allow it, using leverage introduces significant additional risk to a strategy that is prized for its low-risk profile. Leverage can amplify losses if the trade does not proceed as planned, making it generally unsuitable for pure arbitrage.
How do I know if an arbitrage opportunity is profitable?
You must calculate all potential costs (fees, slippage) and compare them to the expected revenue (the funding rate or the width of the price spread). The opportunity is only profitable if the potential revenue exceeds all estimated costs.
