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, 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.
Build it from blocks (or type it in English), backtest it on 5.7 years of minute data in seconds, tweak any parameter, then paper trade it on live data. No card, no broker needed to start.
