Put Credit Spread Issues

Hi everyone, I’ve been trying to learn **put credit spreads**, but I keep running into **conflicting advice**, and I’m struggling to separate signal from noise. For example: * **Tastytrade** often suggests focusing almost entirely on probabilities and IV, and barely using **technical analysis** at all. * Some traders swear by **weeklies**, while others insist on **30–45 DTE**. * Based on a very primitive backtest I ran (mostly indicator-based on lower timeframes), I found that **high IV environments combined with RSI ≤ 30** seemed to perform best—but I’m not confident this approach makes sense long-term. As you can probably tell, I’m still pretty new to credit spreads, and I’d really appreciate some guidance from more experienced traders. # What I’m looking for: **1. Learning resources** Any **videos, books, articles, or courses** you’d recommend to build a solid foundation in options and credit spreads specifically. **2. Strategy insight** What, in your experience, makes a **high-probability / high-conviction put credit spread trade**? More specifically: * What **underlyings** do you trade most often? * Broad ETFs (SPY, QQQ, etc.) vs individual stocks? * How do you **select what to trade**? * What **expiration** do you usually prefer, and why? * How much **technical analysis** do you actually use? * If any, which indicators matter most to you? * How heavily do you rely on the **Greeks** (delta, theta, vega, etc.) when structuring a trade? I’m not looking for a “holy grail,” just trying to understand how experienced traders think about risk, probability, and trade selection when selling put spreads. Thanks in advance—I really appreciate any insight you’re willing to share.
