name crypto-derivatives description Crypto-derivatives strategies — perpetual funding-rate arbitrage, futures term-structure contango/backwardation trading, and option volatility-smile / Greeks analysis. category crypto Crypto-Derivatives Strategies Overview Covers three major crypto-derivatives strategy directions: perpetual funding-rate arbitrage, futures term-structure trading, and options strategies (volatility trading). The main exchanges are OKX and Deribit. Perpetual Funding-Rate Arbitrage Funding-Rate Mechanism Perpetual contracts have no expiry and rely on the funding rate to anchor prices to spot: Funding rate > 0: longs pay shorts (strong bullish sentiment) Funding rate < 0: shorts pay longs (strong bearish sentiment) Settlement frequency: OKX settles every 8 hours (00:00 / 08:00 / 16:00 UTC) Annualized return = funding rate × 3 × 365 Arbitrage Strategies Positive carry arbitrage (funding rate > 0): Long spot + short perpetual = net delta close to zero Return source: collect funding every 8 hours Reverse carry arbitrage (funding rate < 0, less common): Short spot (borrow coin and sell) + long perpetual Return source: collect funding every 8 hours Funding-Rate Signals Funding Rate (8h) Annualized Market Sentiment Strategy Signal > 0.1% > 109% Extreme greed Short signal (rate is unsustainable) 0.03-0.1% 33-109% Bullish bias Positive carry arbitrage is attractive 0.01-0.03% 11-33% Normal bullish Positive carry arbitrage is tradable -0.01~0.01% -11~11% Neutral No arbitrage opportunity < -0.01% < -11% Bearish bias Reverse carry arbitrage or stop-loss < -0.1% < -109% Extreme panic Long signal (rate is unsustainable) Arbitrage Risk Control Risk points: 1. Insufficient margin: the derivatives leg requires margin, and extreme moves can liquidate the account 2. Funding reversal: a positive rate can suddenly turn negative, making the arbitrage unprofitable 3. Basis volatility: changes in the spot-futures basis can cause floating losses 4. Exchange risk: withdrawal limits, downtime, liquidation-mechanism differences Risk parameters: - Leverage: no more than 3x (arbitrage does not need high leverage) - Margin ratio: keep >50% (far from liquidation) - Single-coin allocation: <30% (diversification) - Stop-loss: close when floating loss exceeds expected return over 3 months Term-Structure Trading Basic Concepts Term structure = futures price curve across different expiries Contango: far month > near month > spot - Meaning: market expects higher future prices - Common in bull markets or normal market conditions Backwardation: far month < near month < spot - Meaning: market expects lower future prices or spot shortage - Common in bear markets or after extreme events Term-Structure Metrics def term_structure_spread ( spot_price, futures_prices: dict ) -> dict : """ Args: spot_price: Spot price futures_prices: {expiry: price}, for example {'2026-06': 105000, '2026-09': 107000} Returns: Basis, annualized basis, and structure type """ results = {} for expiry, price in futures_prices.items(): days_to_expiry = (pd.Timestamp(expiry) - pd.Timestamp.now()).days basis = (price - spot_price) / spot_price annualized = basis / days_to_expiry * 365 results[expiry] = { 'basis' : basis, 'annualized_basis' : annualized, 'days' : days_to_expiry, } return results Trading Strategies Strategy Action Applicable Environment Risk Cash-and-Carry Long spot + short futures Significant contango (annualized >15%) Exchange risk Calendar Spread Long near month + short far month Expect contango convergence Basis widening Reverse Calendar Short near month + long far month Expect backwardation convergence Basis reversal Historical Regularities of BTC Term Structure - Bull market: contango annualized 15-40%, quarterly futures premium 5-10% - Bear market: backwardation or contango annualized <5% - Around halving: contango usually widens - Extreme crashes: brief backwardation (such as March 12 and May 19) Options Strategies Overview of the Crypto Options Market Exchange Underlyings Characteristics Deribit BTC / ETH Largest options exchange, >80% market share OKX BTC / ETH Second largest, liquidity still growing Binance BTC / ETH Weaker liquidity Basic Greeks Greek Meaning Crypto-Specific Characteristic Delta Change in option price for a 1% move in the underlying BTC is highly volatile, so Delta changes quickly Gamma Rate of change of Delta ATM options have the highest Gamma Theta Time decay (per day) Crypto trades 7x24, so there are no weekends off Vega Impact of a 1% move in implied volatility BTC IV is often 50-120%, far above traditional assets Rho Rate sensitivity In crypto markets, the rate proxy is DeFi yield Volatility Smile / Skew Characteristics of the BTC option volatility surface: 1. Smile: IV of OTM puts and OTM calls is both higher than ATM IV 2. Skew: usually OTM put IV > OTM call IV (downside-protection demand) 3. Reverse skew: in bull markets, OTM call IV may exceed OTM put IV 25Δ Risk Reversal = IV(25Δ Call) - IV(25Δ Put) > 0: bullish skew < 0: bearish skew (normal state) The larger the absolute value, the steeper the skew Common Options Strategies 1. Short Straddle Action: sell ATM call + ATM put simultaneously Return source: time decay (Theta income) Risk: large move in the underlying Applicable when: IV is considered too high and the market is expected to stay range-bound BTC parameter suggestions: - Consider selling when IV > 80% - Expiry: 7-14 days (faster decay) - Margin: at least 30% of underlying notional 2. Protective Put Action: hold spot + buy OTM put Purpose: hedge downside risk Cost: put premium (about 2-5% of underlying value per month) Applicable when: protecting profits in a bull market BTC parameter suggestions: - Strike: 10-15% below spot - Expiry: 1-3 months - Delta: -0.2 to -0.3 3. Iron Butterfly Action: sell ATM call + sell ATM put + buy OTM call + buy OTM put Return source: profit when the underlying moves within a narrow range Risk: limited (protected by OTM options) Applicable when: low-volatility expectation Maximum profit = premium sold - premium bought Maximum loss = wing width - maximum profit 4. Volatility Arbitrage Action: long / short IV versus realized volatility Long volatility: - Buy straddle + Delta hedge - Applicable when: IV < historical volatility (IV is low) Short volatility: - Sell straddle + Delta hedge - Applicable when: IV > historical volatility (IV is high) BTC IV reference: - IV < 40%: extremely low (long volatility) - IV 40-60%: normal-to-low - IV 60-80%: normal - IV 80-120%: elevated (short volatility) - IV > 120%: extremely high (short volatility, but risk is large) Analysis Framework Daily Monitoring Metrics 1. Perpetual funding rate (8h / annualized) 2. BTC quarterly-futures basis 3. 25Δ Risk Reversal 4. ATM implied volatility 5. Option put/call ratio 6.

Notes This system is for backtest research only : it does not execute live trades; derivatives analysis is for research and backtesting Crypto trades 7x24 : Theta decay never stops, unlike traditional options Liquidity concentration : BTC / ETH options are concentrated on Deribit; liquidity in other coins is extremely poor Extreme volatility : 10-20% single-day BTC moves are not rare, so margin management is critical Exchange risk : centralized exchanges can freeze assets or fail; diversify across venues Data acquisition : OKX data is available through the OKX data source, while Deribit requires an additional interface Regulatory risk : regulation of crypto derivatives is tightening across jurisdictions, so strategy compliance must be assessed separately
