Backtesting Software
Backtesting software for day trading, in your browser
Test intraday strategies against a decade of real Nasdaq futures data without installing anything. Replay 1-minute bars one candle at a time, place simulated orders, and let the journal tell you whether the setup actually works.
Backtesting software replays historical price data so a strategy can be tested before real money is committed. NQ Replay is manual, bar-by-bar backtesting software for day traders: 1-minute NQ and MNQ futures data, real contract P&L, automatic ICT overlays and a journal that scores every trade in R — all in the browser, free to start.

Frequently asked questions
What is backtesting software?
Backtesting software lets you test a trading strategy against historical market data before risking capital. Discretionary backtesting software replays price bar-by-bar so you make the same decisions you would live; automated backtesting software runs coded rules over a data set instead.
Is NQ Replay manual or automated backtesting software?
Manual, bar-by-bar. It is built for discretionary intraday traders — you read the chart, place simulated orders and manage them, so the result reflects your execution, not a script's. There is no strategy-coding language.
What data can I backtest?
1-minute OHLCV data for CME Nasdaq futures (NQ and MNQ), 01:00 to 16:00 ET, sourced from Databento GLBX.MDP3 continuous front-month. Timeframes available are 1m, 5m, 15m, 1h and 4h. Pro accounts reach more than ten years of history.
Do I need to install anything?
No. It runs in the browser on desktop, iPad and phone. There is no desktop client, no data-feed subscription and no NinjaTrader, MetaTrader or Python setup.
How much does it cost?
The free plan includes the backtesting engine, ICT overlays, the journal and the challenge, limited to the last 6 months of sessions and 20 simulated trades per UTC day. Pro is $5/month for the full archive and unlimited trades; Pro+ is $9/month and adds AI analysis grading.
How do I review results?
Every simulated fill is logged with entry, exit, R multiple and tags. The journal shows an equity curve, win rate and expectancy so you can tell whether a setup is actually profitable or just memorable.
