Historical study

T13 base-cost historical backtest

T13 produced a simulated historical return, but failed the finalized study's qualification gates. The result is research evidence, not an approved trading strategy.

How this was tested

Assumptions and limits

Continuous TECL-and-cash simulation from $1,000 initial capital; 10 basis points transaction cost per side, next-eligible-open execution, and settled-cash limits. Sharpe uses the source study's zero-risk-free-rate definition.

  • The candidate did not pass the study's annual consistency, recent-period, and/or drawdown tests; see the technical evidence for exact failed gates.
  • The source market-data archive is owner-held and is not redistributed.
  • The historical period was used during strategy development; this is not an untouched holdout.
  • Historical simulation does not establish future performance or authorize paper or live trading.
