A Bear Call Spread is a net credit strategy: you sell a lower-strike call and buy a higher-strike call with the same expiration. You collect premium upfront. You profit if price stays at or below the short strike; your loss is capped by the long call.

Simple explanation: You think price won’t rise past a certain level. You sell a call there to collect premium, and you buy a higher-strike call to cap risk. You make money if price stays below your short call; you lose a capped amount if price rips higher.

The structure:

• Sell 1 call at lower strike

• Buy 1 call at higher strike

• Same expiration date

• Net result: You receive a credit upfront

Why it works:

• You collect premium from the short call.

• The long call limits your maximum loss if price breaks above your short strike.

• Best for neutral to mildly bearish outlooks.

Bear Call Spread = Sell lower-strike call + Buy higher-strike call (same expiry)

Example Setup:

• ETH current price: $2,000

• Sell: 10 × $2,200 calls for $40 each → +$400

• Buy: 10 × $2,300 calls for $20 each → –$200

• Net credit: +$200 (max profit before fees)

• Period: 30 days

Key Levels:

• Maximum Profit: $200 if ETH ≤ $2,200 at expiry

• Maximum Loss: (Strike diff − credit) × size = ($100 − $20) × 10 = $800 if ETH ≥ $2,300

• Break-Even: $2,200 + $20 = $2,220

Collateral Requirement:

Selling calls requires collateral. For Bear Call Spread, you must lock USDm collateral equal to the short call’s strike × size. The long call caps your maximum loss, so your risk is defined. In this example: $2,200 × 10 = $22,000 USDm collateral locked until expiry or close.

• ETH $2,100 (below short strike): Both expire → keep $200 (max profit)

• ETH $2,220 (break-even): Net $0

• ETH $2,280 (between strikes): Loss = (2,280 − 2,220) × 10 = $600

• ETH $2,300 or higher: Max loss = $800 (capped by long call)

Ideal Scenarios

• Neutral to Mildly Bearish: Expect price to stay below the short strike.

• Range-Bound / Ceiling View: You see resistance near the short strike.

• Income with Defined Risk: Prefer collecting premium, not paying it.

• Lower Cost vs. Buying Puts: You get paid upfront, not outlay premium.

When NOT to Use

• Strong Bullish View: If you expect a breakout above the long strike.

• Very High Vol to the Upside: Risk of reaching max loss.

• No Collateral Available: Short call requires collateral until closed/expiry.

• Maximum Loss is Capped: Known upfront (spread width − credit).

• Collateral Required: The short call needs collateral; long call caps liability.

• Exercise Rules:

• OTM calls can only be exercised once strike is reached.

• ITM calls can be exercised anytime before expiration.

• Time Decay: Works in your favor; you keep the credit if price stays below the short strike.

• vs. Straight Put: Put has unlimited downside profit but costs premium; BCS pays you upfront with capped profit.

• vs. Bear Put Spread: Both are defined-risk bearish; BPS pays premium (debit) and profits more on larger drops; BCS collects premium (credit) and profits if price is flat/down.

• vs. Naked Call: Naked call has unlimited risk; BCS caps risk via the long call.

• vs. Strip: Strip is a volatility bet with bearish bias and higher cost; BCS is an income play with capped risk and works if price stays below a level.

• Real-Time Pricing Updates: Avoid stale quotes; crucial for multi-leg pricing.

• Sub-10ms Execution: Enter both legs instantly; minimize slippage between legs.

• Ultra-Low Fees: gas <$0.005 keeps spreads efficient.

• NFT Positions: The spread is held as an ERC721; transferable and composable.

• Instant Exercise: ITM leg exercise in <10ms; lock in gains immediately.

• Pool-Based Liquidity: No counterparty dependency; immediate settlement of credit and eventual P&L.

• Strike Selection: Pick a short strike near resistance; long strike higher to cap risk.

• Duration: Shorter (7–14d) for faster decay but less time; longer (30d) for more cushion and higher credit.

• Manage Early: If price drops or stays flat and most premium decays, consider closing early to lock profit and free collateral.

• Size Conservatively: Even though risk is capped, ensure max loss fits your risk budget.

The Bear Call Spread is a neutral-to-bearish income strategy: you collect premium upfront, profit if price stays below your ceiling, and cap your loss with a long call. It’s a defined-risk alternative to selling naked calls and a premium-collecting counterpart to buying puts.

Key Takeaways

• Net credit upfront, defined max loss.

• Profit if price is flat or down; capped loss if price rips higher.

• Best for neutral/mildly bearish views with a clear ceiling.

• Time decay works for you; collateral is required for the short call.
