190: SPX Opening Range Breakout (ORB) Strategy Using 0DTE Call Debit Spreads (Part3)

In Part 3 of this series on building an automated SPX 0DTE portfolio, we explore the final strategy we've added to our growing mix of high-frequency, positive expectancy trades: the 30-minute Opening Range Breakout (ORB) Call Debit Spread.

In previous episodes, we discussed the Trend Spread Engine (TSE) credit spreads and the End-of-Day Put Debit Spread (PDS). In this episode, we look at how the ORB strategy adds another layer of diversification by introducing a different combination of win rate, risk/reward, and market conditions.

Topics discussed include:

Why combining strategies with different win rates and risk/reward profiles mattersThe mechanics of a 30-minute Opening Range Breakout strategyWhy we're only trading upside ORBs above the 5-day moving averageThe importance of trade frequency and automationUsing one-minute confirmation for more consistent executionHow portfolio construction can reduce drawdowns and improve consistencyWhy position sizing matters more than any individual trade outcome
