A vertical debit spread using put options — buy a higher-strike put and sell a lower-strike put to profit from a downward SPX move at reduced cost.
A bear put spread is the mirror image of a bull call spread: you buy a put at a higher strike price and sell a put at a lower strike price, both sharing the same expiration date. It is the standard directional structure when you expect SPX to fall.
Example — SPX at 6,000:
Notice the perfect symmetry with the bull call spread. A bull call spread profits as SPX rises toward the upper strike; a bear put spread profits as SPX falls toward the lower strike. Both cost a small net debit, both cap your loss at that debit, and both cap your gain at the width minus the debit. Same structure, opposite direction.

How SPXXL helps:
When SPXXL classifies a bearish session, the engine's projected downside levels and key support zones help you place your short (lower) strike where SPX is realistically expected to travel. The session classification removes guesswork from the most critical decision: which direction to bet.
Important: Options trading involves substantial risk of loss and is not suitable for all investors. This definition is educational and uses SPX for illustration — it is not financial advice.
A two-leg directional options strategy where you buy one option and sell another at a different strike — same type, same expiration — to lower your cost, define your risk, and reduce time decay.
A vertical debit spread using call options — buy a lower-strike call and sell a higher-strike call to profit from an upward SPX move at reduced cost.
A defined-risk options strategy that profits from directional movement — SPXXL's primary recommended structure for most session types.
A contract that gives the buyer the right to sell SPX at a set price (the strike) before expiration — profits when the index falls below the strike minus the premium paid.
A session with sustained directional movement from open to close — price trends in one direction with minimal retracement.
A volatile session with range expansion beyond normal boundaries — often triggered by macro catalysts or institutional repositioning.
The rate at which an option loses value as time passes — accelerates dramatically for 0DTE options as expiration approaches.
