A futures spread strategy is a testable rule for a specific relationship. Define the legs and the reason they might diverge, then challenge the result against individual years, costs and adverse moves.
Choose an economic relationship
A calendar spread compares two delivery months of one market. An intercommodity spread compares related products or benchmarks. A butterfly measures curve shape through three dated months; a crush basket links a raw material to its outputs. Each structure asks a different question. Start with the relationship rather than searching for the best-looking chart.
Define the basket and direction
Write exact symbols, contract years, leg weights, units and quote sign. For a long near/short deferred calendar pair, the value is near minus deferred. Multi-market structures may require unit conversion; butterflies require their 1:−2:1 weights. Direction cannot be understood from a vague label such as “bullish spread.”
Test a repeatable rule
Choose an entry and exit rule, then apply it to the same dated-leg mapping across historical years. Record the complete sample, average and median outcome, winning and losing years, worst interim drawdown and estimated costs. Compare neighboring windows and a held-out period before trusting a result found by optimization.
Control the real trade
Check last trading dates, liquidity, margin for the exact basket, variation cash, slippage and a plan to exit all legs. A lower spread margin does not cap losses. A strategy is not ready just because its historical average rises.
Research the exact spread
Compare dated legs, historical years and current market conditions before using an average curve.
Open Futures Spread Analyzer →Frequently asked questions
Which spread structure is best?
It depends on the economic thesis, data coverage, execution and risk. No single structure is universally best.
Does a high historical consistency score mean a trade will win?
No. It describes a selected sample; regime shifts, optimization bias and future shocks remain.
