# Bullish Call Spread ⎊ Definition **Published:** 2026-03-09 **Author:** Greeks.live **Categories:** Definition --- ## Bullish Call Spread A bull call spread is a strategy where a trader buys a call option at one strike price and sells another call option at a higher strike price. This lowers the net cost of the position while limiting the maximum profit. It is a popular strategy for bullish outlooks with limited budgets. It reduces volatility exposure. - [Bullish Bias](https://term.greeks.live/definition/bullish-bias/) - [Short Call](https://term.greeks.live/definition/short-call/) - [Call Writer](https://term.greeks.live/definition/call-writer/) - [Naked Call](https://term.greeks.live/definition/naked-call/) - [Index Price](https://term.greeks.live/definition/index-price/) - [Debit Spread](https://term.greeks.live/definition/debit-spread/) - [Call Option](https://term.greeks.live/definition/call-option/) - [Bid Ask Spread](https://term.greeks.live/definition/bid-ask-spread/) ## Glossary ### [Put Call Parity Relation](https://term.greeks.live/area/put-call-parity-relation/) Principle ⎊ The put-call parity relation is a fundamental no-arbitrage principle in options pricing, establishing a theoretical relationship between the prices of European call and put options with the same strike price, expiration date, and underlying asset. ### [Margin Call Response Time](https://term.greeks.live/area/margin-call-response-time/) Response ⎊ The Margin Call Response Time, particularly within cryptocurrency derivatives, options trading, and broader financial derivatives, represents the elapsed duration between a margin call trigger and the successful remediation of the deficient margin balance. ### [Bid Ask Spread Aggregation](https://term.greeks.live/area/bid-ask-spread-aggregation/) Analysis ⎊ The systematic aggregation of the bid-ask spread across disparate cryptocurrency exchanges or derivative venues provides a critical view into market fragmentation and latent liquidity. ## Discover More ### [Margin Call Calculation](https://term.greeks.live/term/margin-call-calculation/) ![A cutaway visualization reveals the intricate layers of a sophisticated financial instrument.
