Natural Gas Seasonal Spread

Spreads have reduced risk because you're hedged between months. If prices crash, both legs fall together (losses offset). Margin requirements are lower. You're betting on the relationship between months, not absolute direction. This makes seasonal patterns more tradeable.

The best window is August-October. This is before the winter premium fully builds. Enter when spreads are below the 5-year average for that date. Avoid entering in December when premiums are already at peak.

Typical holding period is 4-10 weeks. Seasonal patterns take time to develop. These are not day trades. Monitor weekly but don't overtrade. Exit when target is reached, stop is hit, or thesis changes.

Storage is crucial. Normal storage: Seasonal patterns work normally. Low storage: Amplifies winter premium (bullish). High storage: Dampens winter premium (bearish). Check the EIA storage report every Thursday (released 10:30 AM ET) and compare to the 5-year average.

Injection season (April-October): Utilities inject gas into underground storage for winter. Prices tend to be lower. Withdrawal season (November-March): Utilities withdraw gas for heating. Prices tend to be higher due to demand.

Calculate the Z-score: (Current Spread - 5-year Average for this date) / Standard Deviation. Z-score < -1.5 = cheap (potential long). Z-score > 1.5 = expensive (potential short). Build a database of historical spreads to calculate averages.

Roll positions 2-3 weeks before near month expiry. Close the existing spread and open a new spread in the next cycle. Calculate roll cost (difference between old and new spread). In contango, rolling costs money; in backwardation, it earns.

Cold forecasts during pre-winter window accelerate premium buildup. Enter earlier if cold winter is forecast. Warm forecasts dampen the pattern - use smaller positions or wait. Use weather spikes for profit-taking.

Limit individual seasonal trades to 2-3% risk of capital. Total seasonal exposure should not exceed 10% of portfolio. This prevents overexposure to seasonal pattern failure while allowing meaningful participation.

Implement a time stop. If no meaningful progress after 4-6 weeks and fundamentals haven't changed, consider exiting. The seasonal pattern may not develop this year. Don't hold indefinitely hoping for the pattern.

Collect 10+ years of daily spread data. Calculate seasonal averages and standard deviations by date. Add regime indicators (storage, weather). Test statistical significance. Use transparent statistical models (multiple regression, seasonal decomposition) for complex patterns. Walk-forward test to validate.

Compare Henry Hub patterns with regional U.S. hubs and European markets (TTF). When all markets show the same seasonal signal, conviction is higher. Divergence may indicate hub-specific factors or arbitrage opportunities. Global confirmation reduces pattern failure risk.

Long calls on winter contracts for defined risk bullish exposure. Bull call spreads reduce premium cost. Protective puts on futures spreads for downside protection. Combine futures spread + long calls for enhanced upside with defined risk.

Use exchange spread orders when available for guaranteed execution. If legging, enter the illiquid leg first (usually far month). Execute during the U.S. cash session (9:00 AM - 2:30 PM ET) for best liquidity. Scale large positions over multiple sessions to reduce market impact.

Track performance by seasonal pattern, regime (storage/weather), and year. Calculate win rate, profit factor, max drawdown for each pattern. Compare to historical patterns. Optimize entry timing, position sizing, and exit rules annually based on results.
