Credit Spread Lab Currently supports SPY 0DTE. Agent comparisons use the displayed point-in-time forecast pipeline; each trade ledger retains its exact pipeline lineage. Positions settle against that session's unadjusted raw close. The $0.026-per-share round-trip fee is a conservative modeled cost—not an observed closing fill—and deliberately charges entry and exit even though positions are held to expiration. Prior hypotheses, validations, fill audits, and benchmarks remain preserved in the Evidence library with their original cohorts and assumptions.
Construct a strategy, test it against historical market data, and trace every result back to its trades.

RESEARCH MODE Changes here recalculate exploratory results; they do not alter frozen validation records.Universe and sample These controls define the dates, cohorts, books, gates, and costs used by every interactive stage. Calls and puts keep independent construction and eligibility rules. Frozen validations, walk-forward evidence, and historical benchmarks do not inherit these exploratory controls.
