Understanding the mechanics behind crypto derivatives trading strategies is essential for traders seeking consistent returns in volatile markets. This guide dives into key quantitative formulas used to evaluate opportunities in both crypto-margined (Crypto-M) and USDT-margined (USDT-M) perpetual and futures contracts. Whether you're assessing funding rate arbitrage, carry trades, futures spreads, or perpetual basis differentials, these models help standardize returns into comparable annualized percentages (APR), enabling smarter capital allocation.
All formulas are designed to be leverage- and balance-agnostic, focusing purely on market data to deliver objective metrics. Below, we break down each strategy with clear explanations, consistent notation, and practical insights.
Funding Rate Arbitrage

Funding rate arbitrage exploits discrepancies in the periodic payments exchanged between long and short positions in perpetual swap contracts. These payments stabilize the contract price relative to the underlying spot or index value.
Crypto-M and USDT-M
- Formula
APR = (P3D perpetual funding / 3) × 365 Explanation
The P3D perpetual funding represents the average funding rate observed over the past three days. Since funding is typically paid every 8 hours (three times per day), this formula annualizes the average daily funding yield.For example, if the average 3-day funding rate is 0.01% per period, the daily rate is approximately 0.03%, leading to an APR of about 10.95% (0.0003 × 365).
- On Crypto-M contracts, the funding rate derives from crypto-denominated perpetuals (e.g., BTC/USD).
- On USDT-M contracts, it comes from stablecoin-denominated perpetuals (e.g., BTC/USDT).
Key Insight
This model isolates funding income from directional price risk, allowing traders to compare funding yields across assets and contract types without assuming position size or leverage. It’s particularly useful during periods of extreme sentiment when funding rates diverge significantly from historical norms.
Carry Trade
The carry trade strategy capitalizes on the premium or discount between a futures contract and its reference price—either a spot index or the USD benchmark—depending on margin type.
Crypto-M
- Formulas
Spread rate = |Futures - USD.Index| / USD.IndexAPR = (Spread rate / Days to expiry) × 365 Explanation
The spread rate reflects how far the futures mark price deviates from the official USD index price for the asset. By dividing by the index, we normalize the spread for comparison across different-priced assets.The APR then annualizes this spread over the remaining lifespan of the contract.
USDT-M
- Formulas
Spread rate = |Futures - Spot| / SpotAPR = (Spread rate / Days to expiry) × 365 - Explanation
In USDT-margined environments, the spot price serves as the benchmark instead of a composite index. The calculation logic remains identical: measure the percentage deviation and scale it annually based on time until expiration.
Key Insight
By normalizing returns using APR, traders can objectively compare near-term versus long-dated contracts across various cryptocurrencies. A steep positive APR may signal strong bullish sentiment, while negative values indicate bearish pressure.

Futures Spread
This strategy evaluates the basis between two futures contracts of differing maturities—commonly known as calendar or time spreads.
Crypto-M and USDT-M
- Formulas
Spread rate = |Mark price of leg 1 - Mark price of leg 2| / min(Mark price of leg 1, Mark price of leg 2)APR = (Spread rate / Days between leg 1 and leg 2) × 365 Explanation
The spread rate measures the relative difference between two futures contracts, normalized by the lower of the two mark prices. This ensures comparability even when prices vary significantly.The APR scales this return over a year based on the number of days separating the two expiration dates.
For instance, if a near-month BTC futures contract trades at $60,000 and a far-month contract at $63,000, with a 90-day gap:
- Spread rate = |63,000 - 60,000| / 60,000 = 5%
- APR = (0.05 / 90) × 365 ≈ 20.28%
Key Insight
This approach avoids distortions caused by absolute price levels and focuses on relative value. Traders often use this to identify contango or backwardation trends across the futures curve.
Perp Basis
Perp basis compares a futures contract against a perpetual swap—another popular derivative instrument that lacks an expiration date.
Crypto-M and USDT-M
- Formulas
Spread rate = |Futures - Perpetual| / PerpetualAPR = (Spread rate / Days to expiry) × 365 Explanation
The spread rate captures how much the futures contract trades above or below the perpetual contract's mark price. Dividing by the perpetual price normalizes the spread.As with other models, the APR annualizes this difference based on days until futures expiry.
Key Insight
This strategy mirrors carry trade logic but substitutes spot/index with perpetual pricing. It’s especially relevant in markets where perpetuals dominate trading volume and serve as de facto benchmarks.
Frequently Asked Questions
Q: What does APR mean in these formulas?
A: APR stands for Annual Percentage Rate. It converts short-term yield into an annualized figure for easier comparison across strategies and timeframes.
Q: Why use the minimum mark price in futures spread calculations?
A: Using the lower of the two prices normalizes the spread percentage, preventing distortion in cases where one contract is significantly more expensive than the other.
Q: Can these formulas predict profits accurately?
A: These models provide theoretical returns under ideal conditions. Real-world outcomes depend on execution costs, slippage, funding fluctuations, and market volatility.
Q: Are these strategies suitable for beginners?
A: While the math is accessible, implementing these strategies requires understanding of derivatives pricing, risk management, and exchange-specific mechanics.
Q: How often should I recalculate these values?
A: Given market dynamics, it’s best to update calculations frequently—especially for funding rate arb and perp basis, which can shift within hours.
Q: Do these models account for trading fees?
A: No. Fees are not included in any formula. Users must factor in taker/maker costs separately when evaluating net profitability.
