MODERATELY BULLISH / DEFINED EXPIRATION BAND
A bull spread lowers one cost by giving up payoff beyond a second strike
A long bull call spread buys a lower-strike call and sells a higher-strike call. A short bull put spread sells a higher-strike put and buys a lower-strike put. With matched strikes, ratios, underlying and expiration, both can produce a rising expiration payoff capped above the higher strike. Their account behavior is not interchangeable.
DEBIT CALL VERSION
Maximum profit is strike width minus net debit
Use the ask for the bought leg and bid for the sold leg when estimating executable debit.
At expiration, before any operational mismatch.
Maximum loss is the net debit plus costs for matched long call spreads.
Illustration: buy the $4,000 call for $55 and sell the $4,100 call for $25. Net debit is $30 per ounce, break-even is $4,030 and maximum gross profit is $70 per ounce. Below $4,000 both expire without intrinsic value.
CREDIT PUT VERSION
Similar endpoint, different obligations and cash timing
Put-call relationships may align theoretical endpoints, but actual bid-ask spreads, margin offsets, fees and early exercise can make one structure materially different.
DECISION RULE
Reject the spread if the required move and remaining reward do not reconcile
Calculate the distance from current underlying futures price to break-even, then compare that required move with time remaining, implied volatility, maximum gain, maximum loss and execution cost. A low debit is not attractive if the higher strike removes most of the payoff before the thesis becomes meaningful.
Both legs must share the same intended underlying and expiration for these formulas. Unequal ratios can create an uncovered tail. Confirm what happens if one leg is exercised or closed while the other remains open.

FREQUENTLY ASKED QUESTIONS
Gold bull spread questions
What is a bull call spread in gold options?
It buys a lower-strike call and sells a higher-strike call with the same underlying futures contract, expiration and ratio. The short call reduces debit and caps upside.
Can a bull spread use puts?
Yes. A bull put spread generally sells a higher-strike put and buys a lower-strike put, creating a credit structure with a bounded expiration loss when properly matched.
Are bull call and bull put spreads identical before expiration?
No. They can share a similar expiration payoff under aligned strikes, but cash flow, exercise, assignment, margin, liquidity and early-exit behavior differ.
