TradeSim is an advanced trading strategy backtesting platform that allows traders to test their strategies against historical market data before risking real capital. It provides comprehensive analytics, risk management tools, and AI-powered insights.

How does backtesting work?

Backtesting simulates your trading strategy using historical market data. TradeSim runs your strategy rules against past price movements to calculate performance metrics like total return, Sharpe ratio, maximum drawdown, and win rate.

What markets does TradeSim support?

TradeSim supports US markets (NYSE, NASDAQ) and Indian markets (NSE, BSE). You can backtest stocks, ETFs, options, and other financial instruments.

Yes, TradeSim is currently in beta and all features are free. We offer free access to backtesting, strategy building, and market data during the beta period.
