Short-history intraday observer
In plain terms
A frequency-native observer for newly listed securities that have enough intraday evidence but not enough genuine daily history. It never converts intraday bars into fake daily years.
How it works
For an exact-identity newly listed common stock or ETF with 20-119 genuine daily sessions, evaluate explicitly frequency-native 1h/4h policies from complete manifest-bound one-minute captures, then publish one canonical end-of-day target. Intraday observations never satisfy daily evidence gates, and the lane retires deterministically at 120 daily sessions.

Expected edge

When a stock trades on unusually heavy volume, the day's move is often just liquidity noise that gets reversed the next day.
When a stock swings widely right at the open and then finishes the day up (or down), it tends to keep going that way the next day.
When a stock closes far away from its average traded price for the day, it tends to drift back toward that average.
