The rules
Buy after a +10% four-week burst and let a 10% trailing stop manage the exit.
- WHEN the market opens · IF not invested AND the 20-day return > +10% · THEN buy with 98% of the sleeve
- WHILE invested · a managed trailing stop follows 10% below the position's high-water mark
Momentum entry, mechanical exit. A +10% gain over 20 sessions signals an asset in a genuine burst; the template buys the strength and hands the exit to a 10% trailing stop that ratchets up beneath the highest close and never moves down. There's no profit target — winners run until the trail catches them.
Good for: high-momentum assets where trends extend — semiconductor and leveraged tech ETFs show the archetype.
Watch out: buying strength means buying high; when a burst immediately reverses, the trail exits about 10% below the entry.
