The rules

Buy extreme 2-day RSI washouts under 10, exit as soon as RSI(2) recovers above 70.

  1. WHEN the market opens · IF not invested AND RSI(2) < 10 · THEN buy with 98% of the sleeve
  2. WHEN the market opens · IF invested AND RSI(2) > 70 · THEN sell the whole position

A short-horizon mean-reversion template popularized by Larry Connors' RSI-2 research. A 2-period RSI under 10 flags a sharp multi-day selloff. In assets with a persistent upward drift, those selloffs have tended to snap back within days. Trades are frequent and short. This is the highest-turnover template in the library.

Good for: liquid index ETFs with strong long-term drift; turnover is high so per-trade edges are small.
Watch out: high trade counts make results sensitive to execution quality; a crash that keeps crashing will hand this template several losing entries in a row.
