Replay Downloader bulk-downloading market replay data for multiple NinjaTrader instruments in parallel

→ Pick instruments. Set a date range. Click Start. Walk away.

NinjaTrader's Historical Data window only fetches one day at a time. If you backtest, replay-practice, or run sim sessions, you've felt the friction. This add-on does the whole grid in one click — and keeps your local replay archive complete as you go.
What it does

Built for serious replay workflows.

⚡

Bulk batch download

Pick any number of instruments — ES, NQ, CL, 6E, GC, RTY — and a date range. The add-on queues every (instrument × date) combination and runs them all, end to end, with retries on transient failures.

📊

Per-instrument progress

Each row shows its own progress bar. See which symbol is on day 12 of 30, which is queued, which finished — live.

🔍

Smart partial detection

Files truncated by a network drop or NT crash get detected and re-downloaded. No more silent partial sessions skewing backtests.

⏭

Skip what's done

Existing complete .nrd files are skipped. Saturdays are skipped. Re-running fills only the gaps.

⇄

Parallel downloads

Optional 2-at-a-time parallelism cuts wall-clock time roughly in half on large date ranges, while staying polite to provider rate limits.

☑

Toggle without removing

Each selected instrument has a checkbox. Turn it off for one run without losing your selection — useful when topping up just one symbol.

🪟

Pop-out activity log + uses your existing data feed

Detach the activity log into its own resizable window so you can keep an eye on it on a second monitor. The downloader connects through whatever data provider NinjaTrader is already using — Rithmic, CQG, Kinetick — no extra subscription, no separate auth.

✓

Trusted publisher

The installer is signed, so Windows installs it cleanly — no scary "Unknown publisher" warning, no "Run anyway" click-through.

How it works

Three steps. No friction.

  1. Install

    Download and run the installer.

  2. Open it in NinjaTrader

    Tools → Replay Downloader. Pick your instruments and a date range.

  3. Click Start. Walk away.

    The add-on downloads everything in the background. When it's done, your replay data is ready to use in NinjaTrader.
