About the SPXXL Session Archive
The SPXXL session archive is a public, searchable database of every SPX 0DTE session classified by the SPXXL engine. Each trading day, the engine analyzes pre-market conditions — including VIX levels, ATM implied volatility, liquidity regime, and gamma exposure — to classify the session into one of six categories: Balanced Day, Trend Day, Expansion Day, Short Covering Rally, Liquidity Sweep, or Volatility Compression.
At 4:05 PM ET, the classification is graded against actual SPX price action. The outcome grade (Correct, Partial, or Missed) measures whether the predicted session type matched reality. This creates a transparent, auditable track record of classification accuracy over hundreds of trading days.
Each session detail page includes the full classification breakdown, confidence scores across all six session types, recommended option structures, initial balance (IB) analysis, and OHLCV market data. Use this archive to study session type frequency, accuracy by confidence level, and seasonal patterns in SPX intraday behavior.
