Selecting Strike Price
Learn how to choose the right strike price to balance premium income with assignment probability. Find your optimal risk-reward point.
The Strike Price Dilemma
Strike price selection is the most important decision in options trading. Go too aggressive (close to the money) and you'll get assigned frequently. Go too conservative (far out of the money) and premiums won't be worth your capital.
Understanding Delta
Delta is your best friend for strike selection. For puts:
- Delta of -0.30 means roughly 30% chance of expiring in-the-money
- Delta of -0.20 means roughly 20% chance of being assigned
- Delta of -0.10 means roughly 10% chance - very conservative
| Delta | Assignment Probability | Premium | Risk Level |
|---|---|---|---|
| -0.40 | ~40% | Highest | Aggressive |
| -0.30 | ~30% | High | Moderate |
| -0.20 | ~20% | Medium | Conservative |
| -0.10 | ~10% | Low | Very Safe |
The Sweet Spot
Most successful wheel traders target the 0.20 to 0.30 delta range:
- High enough premium to be worthwhile
- Low enough probability to avoid frequent assignment
- Good risk-reward balance for the capital used
Using Support Levels
Delta alone isn't enough. You should also consider technical support:
- Identify key support levels on the chart
- Select a strike at or below support
- Confirm with delta that probability is acceptable
- Check the premium meets your minimum requirements
Example Analysis
Stock ABC is trading at $100:
| Strike | Delta | Premium | Monthly Yield | Support? |
|---|---|---|---|---|
| $97.50 | -0.35 | $2.80 | 2.9% | No |
| $95.00 | -0.25 | $1.90 | 2.0% | Yes |
| $92.50 | -0.18 | $1.20 | 1.3% | Yes |
| $90.00 | -0.12 | $0.75 | 0.8% | Yes |
Best choice: $95 strike - good delta, decent premium, at support level.
Strike Selection Framework
- Start with delta - filter to 0.20-0.30 range
- Check support - prefer strikes at or below support
- Calculate yield - ensure it meets your minimum (1%+ monthly)
- Consider the stock - adjust based on volatility and your conviction
Adjusting for Market Conditions
High Volatility Markets:
- Consider lower delta strikes (more conservative)
- Premiums are elevated, so you can go further OTM
- Support levels may be less reliable
Low Volatility Markets:
- May need higher delta strikes for acceptable premium
- Or increase position size with lower delta
- Focus on stocks with elevated IV rank
Common Mistakes
- Chasing yield - picking high delta strikes for premium alone
- Ignoring technicals - delta without support awareness
- Fixed strike approach - using the same delta regardless of conditions
- Not recalculating - what was 0.20 delta last week might be 0.35 now

Monthly Yield = (Premium / Strike Price) × 100
Annualized = Monthly Yield × (365 / DTE)
