✦ Building a replay library one instrument and one day at a time is an evening’s work for a week of data.

This queues the whole job and shows a per-file progress list while it runs.

◆ How a run works
▸ Add instruments, tick the ones you want, set a start and end date
▸ Files land in NinjaTrader’s own replay folder — Playback finds them automatically
▸ Days you already have are skipped; a truncated file is re-fetched, not trusted
▸ An older start date beyond NinjaTrader’s ~90-day window is moved forward automatically

It supplies no data of its own and bypasses no platform limit — it only automates NinjaTrader’s own download, in bulk.
