Iron Condor Strategy

Overview

An iron condor is a defined-risk, defined-reward strategy that profits from low volatility and range-bound price action. It combines a bull put spread and a bear call spread.

Difficulty intermediate Market Outlook: Neutral (range-bound) Risk Level: Moderate Capital Efficiency: High (defined risk)

Strategy Construction

Structure:
1. Sell OTM Put (short put)
2. Buy further OTM Put (long put) - protection
3. Sell OTM Call (short call)
4. Buy further OTM Call (long call) - protection

All options have the same expiration.

Visual Structure

LP SP SC LC spot → P/L max profit (premium received) max loss max loss
iron condor — profit if spot stays inside the inner strikes (SP↔SC) at expiry

Payoff Formula

Net Credit = Premium from short options - Premium paid for long options
Max Profit = Net Credit (when price is between short strikes at expiry)
Max Loss = (Width of either spread - Net Credit) × 100
Breakeven (Lower) = Short Put Strike - Net Credit
Breakeven (Upper) = Short Call Strike + Net Credit

where: Net Credit collected at entry (positive) · Width distance between the short and long strike on either wing (assumed equal) · multiplier ×100 converts per-share to per-contract. does: defines the plateau-and-cliff payoff: flat max profit between short strikes, capped max loss beyond the long wings. Neutral / range-bound trade — ideal high IV crush trade when IV rank is elevated and no catalyst is expected; profits from theta plus IV mean-reversion while spot stays inside the channel.

Entry Rules

  1. Market Conditions:
  2. Low expected volatility / range-bound market
  3. IV Rank > 50% (options are expensive)
  4. No significant catalysts expected before expiration

  5. Clear support and resistance levels identified

  6. Strike Selection:

  7. Short strikes: 0.15 - 0.30 delta (probability of being OTM: 70-85%)
  8. Long strikes: 1-2 strikes beyond shorts (spread width: \(5-\)20 typical)
  9. Wider spreads = higher probability, lower return

  10. Narrower spreads = lower probability, higher return

  11. Expiration:

  12. 30-45 days to expiration
  13. Optimal theta decay period

  14. Avoid earnings and major economic events

  15. Credit Target:

  16. Minimum: 1/3 of spread width
  17. Ideal: 1/2 of spread width
  18. Return on risk: 25-50% per trade

Exit Rules

Scenario Action
50% of max profit reached Close entire position
Price tests short strike Close tested side, let other side run
21 days to expiry Close or roll untested side
Price breaches breakeven Close at loss, do not "hope" for reversal
IV crush occurs early Take profits early (50-75% of max)

Stop-Loss

Stop-Loss = 2x to 3x the credit received

Example:
Credit received: $2.00
Stop-loss: $4.00 to $6.00 debit to close

Max loss on $10-wide spread: $10.00 - $2.00 = $8.00

Position Sizing

Capital Required = (Spread Width - Net Credit) × Number of Condors

Example:
$10-wide spread
Net credit: $2.00
Max risk per condor: $8.00 × 100 = $800

Position sizing:
- Risk 1-2% of portfolio per trade
- With $100k portfolio: risk $1,000-$2,000
- Can sell 1-2 condors

Expected Performance

Metric Value
Win Rate 70-85% (depends on strike selection)
Risk-Reward 1:3 to 1:4 (unfavorable, offset by high win rate)
Return on Risk 25-50% per trade (30-45 DTE)
Annualized Return 15-25% (with proper management)
Max Drawdown Defined and known at entry
Best Market Low vol, range-bound
Worst Market Strong directional move, vol expansion

Risk Management

1. Width Selection

  • Narrow (\(2.50-\)5): Lower capital, higher commission impact
  • Medium (\(5-\)10): Balanced approach, recommended
  • Wide (\(10-\)20): Higher probability, lower return on risk

2. Adjustment Strategies

  • Roll the untested side: Collect additional premium
  • Roll entire condor out in time: More time for thesis to play out
  • Convert to iron butterfly: If price moves toward one side, add position
  • Close and re-establish: At new price levels if thesis invalidated

3. Diversification

  • Don't concentrate on single underlying
  • Spread across uncorrelated assets
  • Different expirations to reduce concentration risk

Greeks Exposure

Greek Iron Condor Position Interpretation
Delta Near zero (at entry) Neutral, but shifts as price moves
Gamma Negative Accelerates losses on big moves
Theta Positive Benefits from time decay
Vega Negative Loses value if IV rises

Checklist

  • [ ] IV Rank > 50% (options are expensive)
  • [ ] No earnings or major events during trade life
  • [ ] Clear support/resistance outside short strikes
  • [ ] Credit received >= 1/3 of spread width
  • [ ] Probability of profit >= 70%
  • [ ] Position size within portfolio risk limits
  • [ ] Exit rules defined (profit target, stop-loss, time-based)
  • [ ] Correlation check: not overexposed to single market factor

Assumptions & Limitations

  1. Requires precise timing — market must remain range-bound
  2. Asymmetric risk: small gains, large losses (offset by high win rate)
  3. Transaction costs matter — commissions on 4 legs per trade
  4. Early assignment risk on short options (especially near dividends)
  5. Margin requirements can be significant for wide spreads
  6. Not suitable for trending markets
