The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

Code is on main:

github.com - Bottom detector

It explicitly used Jim's clusters to backfit a bottom detector using:

Bottom Detector
===============
Identifies major and minor market bottoms using NDX100 breadth indicators
and VIX. Reverse-engineered from a classic NH-NL capitulation model.

Approach:
1. Compute daily NDX100 new 52-week highs/lows from price cache
2. Compute breadth metrics: % new lows, % below 200d MA, NH-NL spread
3. Load daily VIX from FRED (VIXCLS) with dedicated cache
4. Score each day on acute capitulation (spikes, not levels)
5. Detect bottom signals when score exceeds threshold

Strategy (from original model author):
"Ignore signals multiple days in a row, and not buy till the first
day that you DON'T get a signal."

It's built into the telegram and autoupdating bot so reports to you every single day rain or shine.
Here's today's output:

BOTTOM DETECTOR
-----------------------------------
2026-03-20 strength: 81/100
New lows: 5/101 New highs: 1/101 NHNL: -4
VIX: 24
NL volume: 1.6x avg
