Call Ladder (Bull/Bear)
3 calls at laddered strikes — a vertical spread plus an extra short OTM call to reduce the cost. Bull or bear depending on orientation.

Bull Call Ladder at expiration
What is this strategy?
The Call Ladder (also called a <strong>Christmas Tree</strong>) is a variant of the bull call spread that adds an extra short OTM call to reduce or eliminate the cost. Typical construction: long 1 ITM/ATM call + short 1 middle OTM call + short 1 higher OTM call.
The extra out-of-the-money short call generates credit that reduces the debit of the original spread — sometimes leaving a net credit. But it introduces <em>unlimited risk</em> to the upside if the underlying rises sharply beyond the second sold strike.
Useful for moderately bullish traders who want a cheap entry and accept asymmetric upside risk. Bull Call Ladder = ascending strikes; Bear Call Ladder = descending strikes (uncommon).
Construction
| Action | Instrument | Strike | Expiration | Example |
|---|---|---|---|---|
| BUY | 1 Call | ATM (A) | 30-60 DTE | +1 SPY 450 Call |
| SELL | 1 Call | Middle OTM (B) | Same expiry | -1 SPY 455 Call |
| SELL | 1 Call | High OTM (C) | Same expiry | -1 SPY 465 Call |
Example
SPY at $450, a moderately bullish outlook. Call Ladder 450/455/465.
- Call Purchased (450) −$500 premium paid
- Call Sold (455) +$300 premium received
- Call Sold (465) +$100 premium received
- Net Debit $100
- Maximum Gain $400 with SPY between $455 and $465
- Breakeven $451.00 to the upside; above $469 the position loses again
- Loss if SPY = $500 −$3,100 — the third sold call is uncovered
- Maximum Loss Uncapped to the upside: above $465 you are net short a call
The Greeks
Net delta changes a great deal with price: positive below the first sold strike and increasingly negative above the second.
With two sold options against one purchased, net decay works in your favour.
Negative vega: the structure benefits from a fall in implied volatility.
Positive gamma from the purchased call and negative from the two sold. The net turns clearly negative above the upper strike.
Position Management
- 01 Stop Loss at the Short OTM Strike If the underlying approaches the extra short OTM strike, close or roll.
- 02 Buy the Fourth Leg if Price Runs Buying a call above the upper strike converts the structure into defined risk. It costs premium, but it eliminates the unlimited loss.
- 03 Size by the Worst Case Work out the loss on a 10% move higher before opening. If it is not acceptable, cut contracts: the uncovered leg does not forgive sizing errors.
