Narrow Wing IC

No. Narrow wings are best in low-moderate IV when premium is thin. In high IV, wide wings capture more premium and provide valuable buffer. Match width to IV environment - narrow when IV is low, wide when IV is high.

Commissions! With more contracts, total commissions increase. If commissions exceed 10% of credit, your edge is eroded. Calculate net credit after commissions before committing to narrow wings.

Less buffer than standard or wide wings. A 25-point narrow wing has only 25 points between short and long strike. If the underlying moves toward your short strike, you have less room before reaching max loss. This requires faster management.

Per-contract risk is lower (smaller max loss). But probability of reaching that max loss is higher. Total dollar risk can be the same if sized properly. The risk profile is 'higher frequency of smaller outcomes' vs. 'lower frequency of larger outcomes' with wide wings.

You need tight strike intervals available. XJO has 25-point increments which works well. Some stocks may only have A$1 or A$2 increments, which may be too tight or create execution issues. Check strike availability before planning narrow wings.

Typically 25-35 points. 25-point provides maximum efficiency but tightest buffer. 30-35 provides slightly more room with good efficiency. The 'optimal' depends on your risk tolerance and the specific IV environment.

Use systematic rules: set delta thresholds (30-35), profit targets (30-50%), and time exits (7-10 DTE). Don't try to manage discretionarily - the faster pace requires automation or strict rules. Consider trading fewer positions if management becomes overwhelming.

Absolutely - this is recommended! Use narrow wings on low-IV underlyings and wide wings on high-IV names. This optimizes width selection across the portfolio while maintaining diversification.

That's the narrow wing trade-off. With only 25-30 points between short and long strikes, a 50-point move in the underlying covers a large percentage of that buffer. You need to act quickly - waiting too long allows the position to reach max loss.

Often closing is better than rolling for narrow wings. Rolling extends time but if the market has moved against you significantly, you're rolling from a disadvantaged position. Quick exit and re-entry is often cleaner than rolling.

Calculate efficiency score = Expected Return / Standard Deviation of Returns for each width. The width with highest score is optimal for that IV level. Generally: XVI < 15 → 25-30pt, XVI 15-20 → 35-50pt, XVI > 20 → 50-100pt+.

If commissions exceed ~8-10% of expected profit, narrow wings lose their edge. Calculate: (Expected profit per contract × win rate) - (commissions × 2 for round trip). If result is negative or barely positive, narrow wings don't work at your commission rate.

Create rules mapping IV to width: e.g., XVI < 14 → 25pt, XVI 14-18 → 40pt, XVI 18-24 → 60pt, XVI > 24 → 100pt+. Backtest the rules, then implement systematically. Re-evaluate width selection each time you enter a new position.

Narrow wing portfolios have similar total VaR (if sized correctly) but different distribution: higher probability of medium losses, lower probability of maximum losses. Wide wings have the opposite: lower probability of any loss but higher severity when loss occurs. Choose based on risk preference.

Yes, but gamma dominates at short DTE regardless of width. Narrow wings become even more binary (all-or-nothing). Some traders prefer narrow for 0-7 DTE because the efficiency matters when holding time is short and theta decay is rapid. But management must be excellent.
