New research on zero days-to-expiration (Zero-DTE) options shows selling iron condors at specific times can significantly impact profitability. Analysis of SPX iron condors with 30-delta short strikes found that 9:00 AM entries produced the highest win rates and net P&L per trade.

Trading management appears crucial, with positions closed at 10:30 AM consistently delivering strong results across different entry times. Pairing time-based exits with 25% profit targets further enhanced performance.

The findings reinforce that rapid time management remains essential for Zero-DTE success rather than holding positions until market close. This approach delivers both higher profitability and greater consistency for short premium strategies.
