The rules

Buy after a +10% four-week burst and let a 10% trailing stop manage the exit.

  1. WHEN the market opens · IF not invested AND the 20-day return > +10% · THEN buy with 98% of the sleeve
  2. WHILE invested · a managed trailing stop follows 10% below the position's high-water mark

Momentum entry, trailing-stop exit. A +10% gain over 20 sessions marks a burst of momentum. The template buys the strength and exits on a 10% trailing stop that ratchets up beneath the highest close and never moves down. There is no profit target, so winners run until the trail is hit.

Good for: high-momentum assets where trends extend, such as semiconductor and leveraged tech ETFs.
Watch out: buying strength means buying high; when a burst immediately reverses, the trail exits about 10% below the entry.
