Forex Tester Online

Forex Tester Online provides tick-level precision backtesting directly in your browser, simulating real broker conditions across 272 assets.

Tick-Level Precision Backtesting

Experience true backtesting, not simple bar replay, using tick-level historical data for up to 23 years. This ensures simulation accuracy by eliminating future data leakage and bar-by-bar lag, crucial for scalping and high-frequency strategies.

Multi-Asset & Multi-Chart Analysis

Test strategies across an expanded universe of 272 assets, including Forex, Stocks, Indices, and Crypto. Simultaneously analyze up to 10 synchronized charts across different timeframes to gain a comprehensive market view.

Exit Optimizer

Automatically find the optimal stop loss, take profit, and holding time for your entries by testing thousands of combinations against historical market data. This feature also works on imported trade history from platforms like MT4 or TradingView.

Prop Challenge Simulation

Practice specifically for funded account evaluations by setting up the exact rules of common prop firm challenges, including profit targets, max drawdown limits, and minimum trading days.

Blind Testing Mode

Develop pure technical skills without emotional bias by hiding dates, prices, and symbols during testing. This mode preserves seasonality and session trading by keeping the time and day of the week consistent.

Trading Journal Integration

Document your backtesting process directly within the platform. Tag trades, track confidence levels, attach screenshots, and link checklists to your simulated trades for later analytical review.

Validating Algorithmic Trading Robots

Traders can turn their developed algorithms into trading robots within the platform to execute thousands of simulated trades, allowing for rapid refinement of rules and validation before deploying capital.

Simulating Prop Firm Evaluation Periods

Use the Prop Challenge Simulator to rigorously test if a trading strategy meets the strict daily loss limits and profit targets required by proprietary trading firms, ensuring readiness for live evaluation.

Optimizing Exit Parameters

For discretionary traders who know their entry signals but struggle with optimal exits, the Exit Optimizer analyzes backtest results to suggest the best stop loss and take profit levels based on historical performance.

Stress Testing Against Market Crashes

Utilize historical scenarios, including major financial crises and extreme volatility events, to crash-test trading systems, ensuring the strategy remains robust under adverse market conditions.

Analyzing Imported Trade History

Upload real or demo trade logs from platforms like MT5 or NinjaTrader to analyze past performance using the platform's advanced analytics, identifying leaks and areas for improvement in existing trading plans.

Training New Traders with Mentor Mode

Mentors can monitor students' real-time trading sessions within the platform, review specific trades, and share analytics to provide targeted, data-backed coaching.

Can I test multiple currency pairs simultaneously?

Yes, Forex Tester Online allows you to open any number of synchronized charts for different currency pairs after downloading the necessary data, ensuring all charts move forward together.

Does the simulation account for real-world trading costs?

Absolutely. The platform simulates realistic broker conditions, including swaps, spreads, and commissions, providing results closer to live trading than idealized charts.

How much historical data is available for testing?

Forex Tester Online provides up to 23 years of tick-level historical data per symbol, encompassing over 600 million ticks, allowing for comprehensive testing across full market cycles.

Can I use my custom indicators in the backtests?

Yes, you have the capability to code and plug in your own custom indicators, ensuring you test the exact signals you rely on, rather than being limited to built-in options.

Is this tool accessible on different devices?

Since Forex Tester Online runs entirely in the browser, it requires no installation and is accessible on any device with a web browser, avoiding version conflicts.

Can I pause a backtest and resume it later?

Yes, you can pause testing at any point, and the project, including all elements and trade history, will be saved so you can resume testing later.
