Why RN TradeLab

Honest backtesting

Walk-forward 70/30 split: your strategy is judged only on the 30% of history it never saw. Beautiful in-sample curves that collapse out-of-sample are exposed, not hidden.

In-sample vs out-of-sample equity curve

Your own strategies

Write entry logic in the built-in editor with a guided template. Validated automatically, registered instantly - each strategy is its own file.

Strategy code editor

Discipline built in

Trend, time-window and volatility filters plus daily / weekly / monthly loss limits - simulated inside the backtest, with no lookahead bias.

Trend, time-window and volatility filter settings

Stress-tested, not just backtested

Monte Carlo resampling, rolling walk-forward windows, and parameter sensitivity heatmaps - proof a result isn't just one lucky sequence.

Monte Carlo simulation fan chart

Portfolios, not bets

Sector-aware selection and a correlation-aware optimizer that avoids stocks which lose money on the same days. Sharpe, drawdown and rupee P&L under a realistic capital model.

Frequently asked

Do I need a broker account to try it?

No. RN TradeLab runs free on real market data via Yahoo Finance - no account needed. Connect Upstox (NSE/BSE) or Alpaca (US stocks & Crypto) later for full-depth history and live signal scanning, whichever markets you actually trade.

Do I have to switch my broker?

No. RN TradeLab never places orders - a connected broker is used purely as a data feed. Many users open a free account (Upstox or Alpaca) only for data and keep trading wherever they already do.

Does the app trade automatically?

Never. It generates research and signals; every real trade is placed by you, in your own broker app. This is an educational research tool.

Windows says "Windows protected your PC" - is it safe?

That is Microsoft SmartScreen flagging a new, unsigned publisher - normal for small independent software. Click "More info" then "Run anyway". A code-signing certificate is planned as the user base grows.

Will my strategies or data leave my computer?

No. Your broker keys, data, strategies and results live in files next to the app on your PC. Nothing is uploaded. The only thing the app ever sends is a rating, and only if you choose to send one.

Which Windows versions are supported?

Windows 10 and 11, 64-bit.
