The rules

Hold while the trailing 3-month return is positive (above +5% to enter, below 0% to exit).

  1. WHEN the market opens · IF not invested AND the 63-day return > +5% · THEN buy with 98% of the sleeve
  2. WHEN the market opens · IF invested AND the 63-day return < 0% · THEN sell the whole position

Time-series momentum on a quarterly lookback, the horizon much of the academic momentum literature uses. The template enters after a +5% three-month run and exits when the same measure turns negative. The gap between entry (+5%) and exit (0%) is a buffer against flip-flopping around a single threshold.

Good for: assets with long, persistent cycles, such as index, sector and managed-futures ETFs.
Watch out: a three-month lookback is slow; V-shaped crashes and recoveries can see it exit near the bottom and re-enter well off the low.
