# Watchlists — reusable scan configs

Each watchlist is a small JSON config. Say "run my <name> watchlist" (or "update my <name> watchlist")
and MARI re-runs the scan against the saved config, then refreshes the results file.
Say "new watchlist" to answer the 7-question card again and create a new config.

## Layout
- `_template/config.json` — schema/template (copy, never edit)
- `configs/<name>.json` — saved watchlist definitions
- `results/<name>-<YYYY-MM-DD>.md` — dated scan output; latest is also mirrored to `results/<name>-latest.md`

## Re-run semantics
- Same config → same screens → dated results file. Old results are kept for history.
- "Update my watchlist" = re-run with today's data. Config can be patched via chat ("make it midcaps now").
- MARI pulls market data only from TTG MCP servers; screens use ADV, price, gap, short interest,
  distance-to-50MA, VWAP structure, and news-catalyst checks as the config directs.

## Config fields (see _template/config.json)
size_bucket, horizon, screens, min_dollar_volume, price_range, catalyst_rule, list_size, sector_rule, notes.
