Days to Expiration (DTE)
Number of days until an option expires. Affects time value, theta decay rate, and strategy selection.
Days to Expiration (DTE) is one of the most important factors in options pricing and strategy selection. It directly affects time value, theta decay rate, and your potential risk/reward.
DTE and Time Value
Options are "wasting assets" - their extrinsic (time) value decays over time. The relationship isn't linear:
- 45+ DTE: Slow decay, minimal daily theta impact
- 21-45 DTE: Moderate decay, "sweet spot" for many strategies
- Under 21 DTE: Accelerating decay, theta becomes significant
- Under 7 DTE: Rapid decay, options lose value quickly each day
DTE Categories
0-DTE (Zero Days to Expiration)
Same-day expiration options. Extreme gamma, extreme theta. Popular for day traders seeking maximum leverage.
Short-term (1-14 DTE)
Weekly options. High theta decay, good for premium sellers targeting quick profits. Risky for buyers.
Standard (15-45 DTE)
Monthly options. Balanced decay profile. Most common for defined-risk strategies like iron condors.
Long-term (45+ DTE)
Lower theta decay, higher vega exposure. Better for directional plays and stock replacement.
LEAPS (180+ DTE)
Minimal daily decay, significant vega. Used for long-term directional bets and poor man's covered calls.
Choosing the Right DTE
Your DTE choice should match your thesis:
- Quick catalyst: Short DTE for maximum exposure
- Gradual move: Longer DTE to reduce theta drag
- Premium collection: 30-45 DTE balances decay rate and risk
