MULTI-LEG EXPIRATION WORKSHEET
Combine each option and futures leg into one auditable expiration payoff
Start from a bull call spread, bear put spread, straddle, strangle, protective put, covered call or collar, then replace every illustration with your own verified inputs. The tool applies the selected GC or MGC multiplier, keeps premium cash flow separate from expiration value, subtracts entered round-trip commissions and solves continuous piecewise-linear break-even points. It does not estimate pre-expiration value, volatility, probability, margin or execution.

REPRODUCIBLE METHOD
The combined result is the signed sum of every leg
A short option reverses intrinsic value and premium signs, then still subtracts cost.
Direction is +1 for long and -1 for short.
Break-even roots are solved across strike intervals where expiration payoff is linear.
USE BOUNDARY
A clean curve is valid only when the economic objects match
- Use the same option expiration and underlying futures contract for every active option leg.
- Keep GC and MGC in separate worksheets unless contract ratios are explicitly reconciled outside the tool.
- Enter executable bid and ask premiums for the correct side rather than an unfillable midpoint when evaluating a real decision.
- Model broker commissions, exchange fees and slippage separately if they are not included in the entered commission.
- Confirm the exercise and assignment result for every short or in-the-money leg before expiration.

FREQUENTLY ASKED QUESTIONS
Strategy calculator questions
How many option legs can the calculator combine?
Up to four call or put legs plus one optional long or short futures leg. Each option leg can have its own side, strike, premium and contract count.
Can it value calendar spreads?
No. The combined curve assumes active option legs can be evaluated at one common expiration against the same underlying futures contract. Different expirations require a pre-expiration pricing model and time-specific inputs.
Does the chart use live option prices?
No. Premiums and futures prices are user-entered illustrations. GoldObserve does not fetch an option chain or create synthetic live prices.
Why can maximum profit or loss be shown as unbounded?
After the highest strike, the model measures the combined dollar slope. A positive tail slope has no modeled upper profit bound; a negative tail slope has no modeled upper loss bound as the futures price rises.
