Avoid common bull call spread errors involving strikes, debit, liquidity, earnings, assignment, expiration and position management.
Mistakes 1–3: weak construction
Do not choose strikes without a target, focus only on a cheap debit or ignore the resulting breakeven. A low-cost spread can still have a low probability of producing meaningful value.
Mistakes 4–6: execution
Do not leg into the position casually, use illiquid strikes or evaluate only midpoint marks. Model realistic fills and include commissions across opening and closing two-leg orders.
Mistakes 7–9: incomplete risk
Do not ignore earnings volatility, assume maximum profit arrives before expiration or treat the debit as the only operational risk. Early assignment and expiration mechanics still require attention.
Mistakes 10–12: poor management
Do not hold automatically for the last dollar, adjust without recalculating total risk or leave one leg open by mistake. Confirm fills and compare remaining reward with reversal risk.
A practical example
A trader buys a far-OTM narrow spread because the percentage return looks large, ignores a wide bid-ask market and holds through expiration. The forecast, execution and operational risks compound.
This simplified example focuses on the spread at a specific moment and expiration outcome. Live option prices also reflect the underlying price, time decay, rates, dividends, liquidity and transaction costs. Greeks are theoretical estimates, not guarantees.
Frequently asked questions
What is the most common mistake?
Choosing strikes by maximum percentage return without a realistic target and fill.
Can defined risk be unmanaged?

A partial fill can leave unintended long or short option exposure.
