The rules
Enter when price is above the 200-day average; exit only when a 15% trailing stop is hit.
- WHEN the market opens · IF not invested AND yesterday's close > SMA(200) · THEN buy with 98% of the sleeve
- WHILE invested · a managed trailing stop follows 15% below the position's high-water mark
A hybrid of the regime filter and the trailing stop. The 200-day average decides when to get in, and a 15% trail from the position's high-water mark decides when to get out. Winners can run well past the point where a crossover would have exited, and the position gives back 15% from every peak.
Good for: long trends with moderate pullbacks; the 15% trail is wide enough to survive normal corrections.
Watch out: every exit gives back 15% from the peak, and on choppy assets it re-enters above the 200-day repeatedly after each stop-out.
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.
