IDX's Value is regular-board turnover, so NonRegularValue / Value gave
non-regular over regular (BBRI 2026-10-14: 50.91%) instead of the share of
all trading (33.74%). non_regular_bps now divides by regular plus
non-regular value, with a regression test on that fixture. The docs now say
volume, value and the foreign figures are the regular board: IPOT's
regular total matches Value, and in a week of every stock no foreign figure
exceeded regular volume, even with non-regular volume above twice it.

`idx stocks flow SYMBOL` shows what foreign investors bought and sold of a
stock, session by session, from IDX's own daily trading summary: foreign
buy, sell and net volume, net value at the session's average price, and
the share of value traded outside the regular board, with range totals.
Latest 10 sessions by default (--days, at most 60) or --from/--to. The MCP
server exposes it as get_foreign_flow.
- api/idx: pure parser for GetStockSummary (rows dated another session
are dropped) and a provider over curl-impersonate's profile fallback
with a 30 s limit; Cloudflare passes only some fingerprints.
- flow: each session is cached whole by date, so other stocks' flows for
the same sessions need no request. Weekends are never requested.
- Idx::idx_code is shared by broker and flow for the .JK-only check.
