Weekly Iron Condor

No. Singapore only has monthly options expirations. You can only trade 'weekly' iron condors during the expiration week of each monthly cycle - approximately once per month.

Your loss is capped at the maximum loss (width - credit). The wings protect you from unlimited loss. However, you may hit maximum loss quickly. This is why defined risk structures like iron condors are preferred.

Generally no. It's recommended to close by Thursday afternoon or Friday morning to avoid expiration day mechanics like pin risk and potential assignment. The extra few dollars isn't worth the uncertainty.

The first 50% of profit comes relatively quickly due to theta. The last 50% takes longer and exposes you to more gamma risk. Taking 50% captures most expected value with less risk.

IV dropping helps your short options lose value faster. However, in expiration week, vega impact is minimal compared to theta and gamma. Focus more on stock movement than IV changes.

Ideally, use both. Place strikes at approximately 16 delta AND beyond technical support/resistance. If they conflict, favor the technical levels - they represent actual price barriers.

With only 2 days left, there's little time for recovery. Options: (1) Close entire position and accept loss, (2) Close tested side if confident in other direction, (3) Hold if stock is at strong support/resistance. Usually closing is safest.

Iron butterfly has ATM short strikes (same strike for put and call). It offers higher credit but narrower profit zone. Use it only when very confident stock stays at current price. Iron condor is safer with wider profit zone.

Yes, consider 50-75% of your normal monthly condor size. The elevated gamma means P&L swings are larger, so reducing size helps manage risk during the higher-volatility expiration week.

STI offers good liquidity and diversified exposure. Among single stocks, DBS typically has the best option liquidity. Choose underlyings with tight bid-ask spreads and sufficient volume at your desired strikes.

Calculate EV for multiple strike combinations: EV = (Credit × POP) - (Max Loss × (1-POP)). Use historical data or option deltas to estimate POP. Select the combination with highest positive EV while meeting minimum return requirements.

Track aggregate Greeks across all positions. Set limits for total delta, gamma, and theta. Weekly condors add significant negative gamma - ensure this doesn't exceed portfolio limits. Consider weekly condors as an overlay, not core strategy.

Monitor VIX (or local equivalent), daily ATR, IV percentile, and trend indicators. In low-vol regimes, use closer strikes. In high-vol regimes, use wider strikes and smaller size. In trending regimes, avoid condors entirely.

Collect historical option prices for expiration weeks. Simulate entry on Monday, track daily P&L, apply exit rules. Test across multiple years covering different regimes. Calculate win rate, profit factor, max drawdown. Validate out-of-sample.

If trading condors on correlated underlyings (e.g., all Singapore banks), sum their gamma exposure as if they're one position. Apply combined position limits. Consider offsetting correlations with uncorrelated underlyings or hedges.
