Date range
Define start and end dates to prepare complete sessions, not just one isolated day.
NinjaTrader Market Replay
Automated NinjaTrader Market Replay Downloader
Select a date range, enter the markets or contracts you want to prepare, and let AT Market Replay Data Pro generate and run an automated queue of available downloads.
Real workflow problem
Stop preparing Replay day by day when you need several markets.
The value is reducing the repetitive work before analysis: dates, contracts, queue, progress and process control.
Multiple markets
Enter several instruments or contracts in one workflow, with flexible input formats.
Automated queue
The AddOn generates the queue and runs available Market Replay downloads with statuses, progress and technical log.
Before / after
Manual versus automated
The tool does not promise unavailable data or trading results. It automates the operational Market Replay preparation process within NinjaTrader’s real availability limits.
Manual workflow
Repeating date, instrument, download and review for each session takes time and increases the chance of missed items.
Automated workflow
Select dates and markets, review the queue and run the process from a dedicated interface.
Professional use
Practice, session review, training, visual validation and preparation of NinjaScript testing sessions.
Professional foundation
Market Replay data: the difference between checking history and reproducing the market.
When reviewing signals, developing indicators, validating AddOns, preparing visual backtesting or creating training sessions, data quality matters. Market Replay allows users to work with a more faithful reproduction of the session available in NinjaTrader than conventional aggregated historical data.
AT Market Replay Data Pro helps prepare that workflow with more structure: multiple markets, date ranges, a visible queue, statuses and technical logs. It does not promise trading results; it helps users work with more appropriate data when the goal is to analyse how the market actually behaved during the session.
Operational time saving
Estimated active time: manual download vs AddOn workflow
Actual download time depends on servers, connection quality and availability. This table measures the user’s active time: selecting, confirming, checking and repeating.
| Scenario | Downloads | Estimated manual process | With the AddOn |
|---|---|---|---|
| 1 market · 1 day | 1 | 1.5–3 min | 1–2 min |
| 3 markets · 1 day | 3 | 4.5–9 min | 1–2 min |
| 3 markets · 3 days | 9 | 13.5–27 min | 1–3 min |
| 3 markets · 1 market week | 15 | 22.5–45 min | 1–3 min |
| 3 markets · approx. 1 month | 60 | 90–180 min | 2–5 min |
Conservative estimate based on 1.5–3 minutes of manual intervention per individual download. Transfer time may still exist, but repetitive user intervention is significantly reduced.
Clear limitations
Prudent automation, without total availability promises.
Final data availability depends on NinjaTrader Market Replay servers and limits. AT Market Replay Data Pro helps prepare, launch and control the workflow, but it does not create data that is not available.
