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.

The problem

More data.
Less clarity.

Your edge is not a feeling. It is a system. TradeSim turns scattered intent into a workflow you can inspect.

Setups stay in your head.

If entry, exit, and sizing rules are not written down, you cannot backtest the idea or know what you actually changed when P&L moves.

Spreadsheets ignore decay.

Weekly F&O premiums require intraday tick replay. Pasting daily NSE sheets hides decay, slippage, and the true cost of execution.

Context dies between tools.

Screening symbols in one terminal, executing in another, and journaling from memory leaves your strategy disconnected.

How it works

Simple steps. Serious process.

From strategy formulation to historical backtesting to terminal simulation, all in one unified workspace.

Define your rules.

Compose indicators, price constraints, and logical entry/exit trees. Hand them to the engine to evaluate bar by bar.

Who it is for

Built for traders
who measure.

If you care about evidence, process, and review, TradeSim is designed for your workflow.

Discretionary options traders.

Analyze Open Interest clusters and straddle/strangle pricing. Verify setups on historical tape and run option spread paper fills before exposing capital.

Systematic builders.

Encode technical crossovers, ATR stops, or custom indicators into conditions. Backtest parameters across regimes and hand setups off to the terminal.

Curious researchers.

Screen symbols across market metrics, study peer-sector cohorts, and tag journaling notes to build a reproducible log of evidence.

The TradeSim system

Built to improve
over time.

A terminal-first path: paper execution before capital, replay before conviction.

Day 1

Open the terminal, place your first paper order, and watch the blotter update in real time. Scan the options chain or stock screeners, build a simple straddle or a fundamental entry, and see how fills behave under live market conditions without risking capital.

Week 1

Turn ideas into rules, run a backtest across years of data, then replay the run on chart to see if execution matches intent. Refine your strategy with regime filters, sector tailwinds, or IV conditions, and compare multiple setups side by side.

Week 2+

Journal outcomes, reconcile positions against your written rules, and review every trade with sharpe, drawdown, and attribution. Build a reproducible track record, share your playbooks with peers, and optionally connect a broker when you are ready to go live.
