What Chart Scanner actually does
The Chart Scanner is the first step of a day trade. It reads free Yahoo Finance charts for thousands of US-listed common stocks, ordinary shares and ADRs, then lists only the charts that match a written rule: 20-day closing-high breakouts, bull flags, reclaimed 20-day averages, oversold conditions and oversold bounces.
It is a list of charts that match a rule, not a list of stocks to buy. Every setup is written to trader/watchlist.json with the numbers behind it, so the news, entry and time-machine skills work from the same facts instead of a screenshot.
Capabilities
What it helps your agent ship

Workflow
The process the skill follows
A repeatable sequence keeps the agent from jumping straight into edits before it understands the job.
- 01
Build the universe
Pull US-listed common stocks, ordinary shares and ADRs from Nasdaq Trader, then cache the list.
- 02
Run the daily scan
Check daily closes for the pre-market setups before the opening bell.
- 03
Scan the open
After 9:50 AM ET, scan 5-minute bars for opening-range breakouts.
- 04
Pin the clock
Use --at or --now to cut the scan at an exact New York time so the result is repeatable.
- 05
Write the watchlist
Save trader/watchlist.json for the news, entry and time-machine skills.
