Core Concepts for Spread Trading
01
Basis Spread
The basis spread is the price difference between a perpetual futures contract and its underlying spot asset. This spread is primarily driven by funding rates and market sentiment.
- A positive basis indicates futures are trading at a premium to spot.
- A negative basis indicates futures are trading at a discount.
- Traders exploit this by longing the underpriced leg and shorting the overpriced leg to capture convergence.
02
Calendar Spread
A calendar spread involves taking offsetting positions in futures contracts with different expiration dates, typically on the same asset. In perpetual markets, this is simulated using contracts with different funding rate periods or on different protocols.
- Capitalizes on differences in funding rate schedules or liquidity.
- Aims to profit from the term structure of futures prices.
- Reduces directional market risk compared to a naked position.
03
Intermarket Spread
An intermarket spread trades the price relationship between correlated assets across different markets or protocols. This strategy bets on the convergence or divergence of these relationships.
- Example: Trading the price ratio between ETH perpetuals on dYdX and GMX.
- Requires monitoring liquidity depth and fee structures on each venue.
- Profit comes from relative value, not absolute price moves.
04
Funding Rate Arbitrage
Funding rate arbitrage seeks to capture payments from the funding rate mechanism of perpetual contracts while hedging the underlying price risk. It is a core component of basis trading.
- Involves holding a spot position and an opposing perpetual position.
- The trader earns the funding rate if it is positive on their perpetual side.
- Requires managing collateral efficiency and exchange-specific risks.
05
Delta-Neutral Positioning
A delta-neutral portfolio is constructed to have zero net exposure to the price movement of the underlying asset. Spread trades are inherently designed to achieve this.
- The combined delta of the long and short legs offsets to approximately zero.
- Profit is derived from changes in the spread, not the asset's price.
- Requires continuous rebalancing to maintain neutrality as prices move.
06
Liquidity & Slippage
Liquidity depth and slippage are critical execution risks in decentralized spread trading. Orders on two legs must be filled near-simultaneously at favorable prices.
- Low liquidity can lead to high slippage, eroding potential profits.
- Strategies often utilize limit orders, TWAP execution, or specialized aggregators.
- Understanding the order book dynamics on each DEX is essential for feasibility.
Types of Perpetual Spread Strategies
Time-Based Arbitrage
Calendar spreads, also known as time spreads, involve simultaneously taking long and short positions on the same asset but with different expiry dates on perpetual futures contracts. This is achieved by using protocols like GMX or dYdX that offer markets with varying funding rate periods or by utilizing different perpetual protocols with correlated but temporally distinct price action.
Key Mechanics
- The strategy capitalizes on the convergence or divergence of funding rates between contracts. A trader might go long on a contract with a lower (or negative) funding rate and short one with a higher rate, earning the rate differential.
- It exploits term structure in the futures curve (contango or backwardation). In contango, longer-dated contracts trade at a premium, making a short-long spread potentially profitable as prices converge at expiry.
- Requires monitoring funding payment schedules and liquidity across different maturities or protocols to manage roll-over risk.
Practical Example
On dYdX, you might go long ETH-PERP and short a 3-month ETH quarterly future if you anticipate the funding rate for the perpetual will decrease relative to the quarterly, or if you believe the futures curve will flatten. Your PnL is driven by the change in the price difference (the spread) and the cumulative funding payments received/paid.
Executing a Spread Trade
Process overview
1
Analyze Market Conditions and Select Legs
Identify the spread opportunity and select the perpetual contracts.
Detailed Instructions
Begin by analyzing the funding rate differential and price correlation between two assets or markets. The goal is to identify a temporary price dislocation where one contract is relatively expensive (high funding) and the other is cheap (low or negative funding). For example, you might analyze the ETH/USDC and BTC/USDC pairs on a DEX like dYdX or GMX. Use on-chain data from oracles and protocol APIs to check the current and predicted funding rates. Select the long leg (the undervalued contract you will buy) and the short leg (the overvalued contract you will sell). Ensure both contracts have sufficient liquidity to avoid excessive slippage on entry and exit.
- Sub-step 1: Query the current funding rate for target perpetuals using the protocol's subgraph or API endpoint.
- Sub-step 2: Calculate the historical spread and its standard deviation to gauge the mean reversion potential.
- Sub-step 3: Verify available liquidity by checking the order book depth or pool TVL for the selected markets.
javascript// Example: Fetching funding rates from a hypothetical subgraph query const query = ` query { markets(where: {name_in: ["ETH-PERP", "BTC-PERP"]}) { id currentFundingRate indexPrice } } `;
Tip: Consider using a data dashboard like Dune Analytics to track funding rate histories and correlations across multiple protocols.

Calculate Position Sizing and Collateral
Determine the notional value and required margin for the trade.
Detailed Instructions
Position sizing is critical for managing risk in a spread trade. The legs should be delta-neutral or have a targeted hedge ratio, meaning the notional value of the long and short positions should be roughly equivalent to avoid directional market exposure. Calculate the notional value per leg: Notional = Contract Size * Index Price. For a 1:1 ETH/BTC spread, if buying 1 ETH contract at $3,000 and selling 1 BTC contract at $60,000, the notionals are $3,000 and $60,000 respectively—this is not balanced. You must adjust the contract quantities to achieve dollar neutrality. Furthermore, calculate the total initial margin requirement, which is the sum of the margin needed for each isolated position, though some protocols may offer cross-margin benefits for correlated pairs.
- Sub-step 1: Determine the hedge ratio (e.g., based on beta or volatility) to calculate equivalent dollar amounts.
- Sub-step 2: Compute the required margin for each leg using the protocol's margin formula (e.g., 5-10% of notional).
- Sub-step 3: Ensure your wallet holds sufficient collateral (e.g., USDC) in the protocol, accounting for potential maintenance margin calls.
solidity// Conceptual calculation for dollar-neutral sizing // For ETH at $3000 and BTC at $60000, to get $30k exposure each: ethContracts = 30000 / 3000; // 10 contracts btcContracts = 30000 / 60000; // 0.5 contracts
Tip: Always include a buffer (e.g., +20%) above the minimum margin to withstand price volatility and funding rate payments.
3
Simultaneously Execute the Long and Short Orders
Place the opposing market orders or limit orders on the DEX.
Detailed Instructions
Atomic execution or near-simultaneous placement is essential to avoid legging risk, where one side fills and the other doesn't, leaving you with an unintended directional position. Most decentralized perpetual exchanges do not have native spread order types, so you must execute two separate transactions. Use a smart contract wallet or a meta-transaction bundle via a service like Gelato or a protocol's SDK to submit both orders in a single block. Alternatively, use limit orders with tight slippage tolerances. For example, on Synthetix's Perps V3, you would call openPosition() for the long market and openPosition() for the short market in quick succession, specifying the marketId for each leg. Monitor the mempool status to ensure both transactions are confirmed.
- Sub-step 1: Prepare and sign both transaction objects for the long buy and short sell orders.
- Sub-step 2: Submit transactions via a bundler or manually with high gas priority to ensure same-block inclusion.
- Sub-step 3: Verify both order fills by checking the transaction receipts and your updated position on the protocol's interface.
javascript// Pseudocode for bundling two perp orders using an SDK const tx1 = perpProtocol.openPosition(marketIdLong, sizeLong, isLong); const tx2 = perpProtocol.openPosition(marketIdShort, sizeShort, isLong); const bundleId = await gelato.sendBatch([tx1, tx2]);
Tip: Test the execution logic on a testnet first to estimate gas costs and confirm the atomicity of your method.
4
Monitor and Manage the Open Position
Track the spread, funding flows, and risk metrics.
Detailed Instructions
Once the spread trade is live, active management is required. Continuously monitor the PnL of each leg and the net funding rate cash flow. The profit comes from the convergence of the spread (price movement) and the net funding received (if shorting the high-funding leg). Use a dashboard or custom script to track the mark price difference between your positions. Be aware of margin ratio fluctuations; if one leg moves sharply against you, it may trigger a margin call on that isolated position even if the net spread is profitable. You may need to post additional collateral. Also, monitor for protocol-specific risks like insurance fund depletion or oracle staleness that could affect liquidation prices. Set up alerts for significant changes in the funding rate differential or when the spread reaches your target profit level.
- Sub-step 1: Schedule a script to query your position data and the live spread every few blocks.
- Sub-step 2: Calculate the unrealized PnL and net funding accrued since entry.
- Sub-step 3: Check your account's health factor or margin ratio on the protocol's smart contracts.
python# Example: Simple monitoring logic for net funding accrual # Assumes funding is paid/accrued every hour hours_open = (current_time - entry_time).total_seconds() / 3600 net_funding_flow = (short_leg_funding_rate - long_leg_funding_rate) * notional * hours_open
Tip: Consider using a DeFi portfolio tracker like DeBank or Zapper to aggregate your perpetual positions across protocols for a unified view.
5
Close the Trade and Realize Profit/Loss
Exit both positions to capture the spread convergence.
Detailed Instructions
Closing the spread involves executing the reverse trades: selling the long leg and buying back the short leg. Aim for simultaneous closure to lock in profits and avoid legging risk, similar to entry. Determine your exit condition, which is typically when the spread narrows to a historical mean or a predefined profit target. Before executing, calculate the final PnL, including all funding payments and trading fees. On the DEX interface or via smart contract call, initiate a closePosition or submitCloseOrder for each market. Ensure you account for the exit fee structure, which may differ from the entry fee. After the transactions confirm, verify that your position sizes are zero and all collateral (minus fees and PnL) has been returned to your available balance. The realized profit will be in the settlement asset (e.g., USDC).
- Sub-step 1: Place market orders or tight limit orders to close both positions, ideally in a bundled transaction.
- Sub-step 2: After closure, query the protocol to confirm zero open interest for your account in both markets.
- Sub-step 3: Calculate the final realized PnL: (Price Change PnL) + (Net Funding Received) - (Total Fees).
solidity// Example interface for closing a position on a typical perp DEX IPerpetualDEX(protocolAddress).closePosition(marketId, positionSize);
Tip: If the spread hasn't converged and you need to exit, consider closing the legs independently with limit orders to minimize slippage, accepting the residual legging risk.

Risk Management and Considerations
Essential protocols and concepts to manage exposure and capital efficiency when executing spread trades on decentralized perpetuals.
01
Funding Rate Arbitrage Risk
Funding rate differentials are the core of the strategy but carry execution risk.
- Rates can flip or converge before your trade is filled, erasing the edge.
- High volatility can cause unexpected payments, turning a profitable spread negative.
- Monitoring rate history and using limit orders is critical to mitigate this timing risk.
02
Liquidation Cascades
Correlated liquidations can destabilize a spread position.
- A sharp move on one leg can trigger a margin call, forcing closure of the entire position.
- This can occur even if the net PnL of the spread is positive.
- Users must maintain higher collateral buffers and set conservative leverage to avoid being caught in a cascade.
03
Protocol-Specific Slippage
Slippage tolerance must be set per exchange due to varying liquidity pools.
- Executing large legs on low-liquidity markets can significantly impact entry/exit prices.
- This slippage can consume the funding rate premium.
- Strategies should factor in pool depth and may need to split orders across multiple venues.
04
Cross-Margin vs Isolated Margin
Margin account type dictates your risk exposure.
- Isolated margin protects other positions but requires precise allocation per trade.
- Cross-margin pools collateral, increasing capital efficiency but exposing all funds to a single leg's liquidation.
- Choosing the right mode is essential for portfolio-level risk management in multi-leg strategies.
05
Oracle Price Manipulation
Oracle latency or manipulation can create temporary but critical price discrepancies.
- A manipulated price on one oracle can trigger an incorrect liquidation on your position.
- Spreads relying on different oracles per leg are especially vulnerable.
- Researching the security and decentralization of each protocol's oracle is a key due diligence step.
06
Gas Optimization & Execution Cost
Transaction cost overhead can negate profits from small spreads.
- Opening/closing two positions and managing them requires multiple on-chain transactions.
- Network congestion during high volatility increases costs precisely when rebalancing is needed.
- Profitable strategies must account for gas fees as a fixed cost per cycle.
Frequently Asked Questions
Funding rates are periodic payments between long and short positions to peg the perpetual contract's price to the underlying spot index. The mechanism calculates a rate based on the difference between the mark price (derivative price) and the index price (spot price). If the mark price is above the index, longs pay shorts to incentivize selling; if below, shorts pay longs. For example, on GMX or dYdX, this rate is typically applied every 8 or 1 hour, often ranging from -0.05% to +0.05% per interval, which can annualize to significant figures in volatile markets.
- The rate is a function of the premium/discount and an interest rate component.
- It is settled directly from traders' margin, not from the protocol treasury.
- High positive funding can signal strong bullish sentiment and create a cost for maintaining long positions in a spread.
