What you should see

bhavcopy: downloaded=3 skipped=0 failed=0 root=/…/nse-data

• downloaded — new files written
• skipped — already present (--skip-existing default)
• failed — missing days or HTTP/HTML responses (counted in the summary; process exits 1 only with --strict)

Default date walking uses the XBOM calendar where exchange-calendars covers the window (from 2006-08-16). Earlier dates use Monday–Friday only (no holiday calendar). Use --all-calendar-days only when you intentionally want weekends/holidays.

Where files land

  raw/bhavcopy/YYYY/YYYY-MM-DD.csv
  raw/fo_bhavcopy/YYYY/YYYY-MM-DD.csv
  raw/full_bhavcopy/YYYY/YYYY-MM-DD.csv

index-history writes into the same raw/index_closes/YYYY/YYYY-MM-DD.csv files as index-closes (one row per index per day), so NSEData(root).index(name).ohlc() returns one continuous series across NSE's renames with no extra step.
