Multi-leg strategies
How do transaction costs and multi-leg commission drag erode the profitability of Butterfly spreads?
By Easy Money Scanner · Educational reference · Not investment advice
The short answer
Multi-leg Butterfly spreads involve four separate option legs, each incurring commissions and bid-ask spread costs, which can consume a meaningful share of the position's limited profit potential.
How it works
Because butterflies are often entered for small net debits, fixed per-contract fees and wide spreads on less-liquid strikes disproportionately reduce net returns compared to single-leg trades.
An example
A butterfly costing $0.50 net debit with $0.05 commission-equivalent drag per leg across four legs can see a meaningful percentage of potential profit consumed by costs alone.
Risk & limitations
High-frequency adjustments or rolling increase cumulative costs further; traders should factor all-in transaction costs before assuming a butterfly's theoretical payoff is achievable.
