Payoff anchors for bull and bear vertical spreads
Pick the vertical that matches the directional view, then lock largest loss, breakeven, and largest gain. Editorial reading: those three payoff anchors keep entry, exit, and standing aside as one testable procedure.
- A rising-market forecast is expressed with two vertical constructions: a call debit spread and a put credit spread.
- Each vertical is checked at three payoff anchors: largest loss, the zero-result underlying price, and largest gain.
- Bearish put-debit and call-credit constructions reverse the gain and loss sides of the bullish pair and still use the same three checkpoints.
- Editorial reading: lock the anchors before writing entry, exit, or abstention rules so the option spread stays one procedure.
From forecast to geometry
An option spread is a paired long and short options position treated as a single procedure whose payoff can be checked before any entry rule is written. A vertical debit spread is a same-expiration spread that pays net premium to own the nearer option and sell the farther strike, so both loss and gain are capped.
Editorial reading: treat construction as a forecast-to-geometry drill. First pick the vertical that matches the directional view. Then lock the three payoff anchors so entry, exit, and standing aside stay one testable procedure.
Bullish call-debit and put-credit constructions
A rising-market forecast is expressed with two vertical constructions: a call debit spread and a put credit spread.
A call debit spread is a bullish vertical that buys the lower-strike call and sells the higher-strike call for a net premium outlay. On a call debit spread, the largest loss equals the net premium paid to open the position. A call debit spread is at a zero net result when the underlying equals the lower strike plus the premium paid. After the underlying moves through breakeven, a call debit spread's value rises only until the higher strike, where the short call stops further gain.
A put credit spread is a bullish vertical that sells the higher-strike put and buys the lower-strike put, collecting net premium. On a put credit spread, the largest loss equals the gap between the two strikes minus the premium collected. A put credit spread is at a zero net result when the underlying equals the short higher strike minus the premium received.
Bearish put-debit and call-credit constructions
Bearish put-debit and call-credit constructions reverse the gain and loss sides of the bullish pair and still use the same three checkpoints: largest loss, breakeven, and largest gain.
A put debit spread is a bearish vertical that buys the higher-strike put and sells the lower-strike put for a net premium outlay. A put debit spread's largest loss is the premium paid, and its largest gain is the strike gap minus that premium.
A call credit spread is a bearish vertical that sells the lower-strike call and buys the higher-strike call, collecting net premium. A call credit spread's largest gain is the net premium received. Its largest loss is the strike gap after subtracting premium received. Its zero-result price is the short lower strike plus premium received.
Keep entry, exit, and standing aside as one procedure
Editorial reading: once largest loss, breakeven, and largest gain are written down, the same geometry governs whether a rule may enter, must exit, or should stand aside. The archive presents that order as construction work, not as a claim about later results.
