SPX & SPY Market Behavior

SPX and SPY 0DTE options move quickly, and trading results are often influenced as much by market conditions as by direction. Option pricing, volatility changes, overnight gaps, and Federal Reserve announcements can significantly affect how trades behave during the session.

The articles below explain situations we encounter regularly during live trading and how those conditions influence trading decisions. These articles are educational and are not trade alerts or signals. Their purpose is to help traders interpret what they are seeing and understand why certain sessions offer opportunity while others require patience.

These insights come directly from real trading experience. By understanding how pricing, volatility, and timing interact during the trading day, traders can better interpret market behavior and avoid common mistakes that occur when 0DTE options are treated like ordinary trades.
