Bear Call Spread

BTC just ripped to 93k on a short squeeze and you think the move is overextended. You do not want to short spot. That is unlimited risk and you have seen what happens when a squeeze extends. But you are comfortable saying: BTC is not going above 98k in the next 10 days. The bear call spread lets you sell that view. You sell a call, buy a cheaper call above it for protection, and pocket the difference. If BTC stays below your short strike, you keep the credit. This is a credit spread.

What You Do​

The SetupYou receive premium
Sell1 call at the lower strike (K1)
Buy1 call at the higher strike (K2), same expiry
Max Profit

Max Loss

Breakeven
K1 + net credit
Margin
Width - credit (venue-specific)

How the P&L Works​

  1. Below K1 (short strike). Both calls expire worthless. You keep the full credit. BTC did what you expected: nothing dramatic to the upside.
  2. Between K1 and K2. The short call is ITM, eating into your credit. Every dollar above K1 costs you a dollar.
  3. Above K2. Both calls ITM. Max loss reached. The long call caps the damage. Without it you would be naked short a call watching BTC go parabolic.

Worked Example: BTC 98k/104k Bear Call Spread​

BTC at 93,400. 10 DTE. IV at 67% (elevated after the squeeze).

Sell 98k call at 2,350. Buy 104k call at 780. Net credit: 1,570. Width: 6,000.

Max profit: 1,570 (the credit). Max loss: 4,430 (width 6k minus credit). Risk/reward: 0.35:1. Breakeven: 99,570.

BTC needs to rally another 6.6% from 93,400 before you start losing money. You have 6,170 of room. The short strike is 4.9% above current spot and after a squeeze, that is a lot of ground to re-cover in 10 days.

When to Use​

  • Bearish or neutral. You do not need BTC to drop. You just need it to not rally through your short strike. The thesis is "this level holds," not "this thing dumps."
  • IV is elevated. Post-squeeze, post-CPI, post-FOMC -- whenever IV is pumped, the credit you receive is fatter for the same strikes. If the catalyst passes without follow-through, IV collapses and both legs deflate. Since you are net short, that deflation is pure profit.
  • You want to collect premium rather than pay for a bearish directional bet. Cash in the account on day one.
  • You want a high probability of profit. Selling OTM calls with a 25-delta short strike gives you roughly a 75% chance of full profit.
💡

Bear call spreads are the go-to trade after a volatility spike. IV is elevated, call premiums are juiced, and you are betting that the excitement fades. If the catalyst passes and IV mean-reverts, you profit from both theta decay and vega crush simultaneously. That double tailwind is why experienced traders time credit spreads around events rather than randomly.

Greeks at a Glance​

Greek
Sign
What It Means
Delta
-
Benefits from BTC falling or staying flat. You want spot to drift away from your short strike.
Gamma
-
Negative gamma is the tax you pay for positive theta. As BTC rallies toward K1, your negative delta grows and losses accelerate.
Theta
+
Every passing day erodes both legs. Since you sold the more expensive one, net decay flows to you.
Vega
-
Rising IV hurts. If BTC threatens a breakout and IV spikes, your short call swells faster than your long call decays.
Common Mistakes
The mistakeSelling bear call spreads into a trending market because "it has to pull back eventually." Trends last longer than your margin.
The realityBear call spreads work best in range-bound or post-catalyst environments. In a sustained uptrend, your short strike gets tested repeatedly. Negative gamma makes each test more painful than the last. Wait for the trend to show signs of exhaustion before selling calls against it.
The mistakeChoosing strikes too close to current spot for a fatter credit. "The $95k/$101k spread pays way more than the $98k/$104k." Yes, and it also gets tested immediately.
The realityThe credit you receive is compensation for the probability of loss. A fatter credit means a higher probability of being tested. Selling a 40-delta call because the credit is juicy defeats the purpose of a high-probability strategy. Stick to 20-30 delta short strikes.
The mistakeHolding through a breakout because "there is still time." By the time BTC is trading at your short strike with 5 DTE, you are already losing and gamma is against you.
The realityClose at 2x credit received and move on. A $1,570 credit turning into a $3,140 loss is manageable. A $1,570 credit turning into a $4,430 max loss is not. Mechanical stops beat hope.
