AI Backtester

Everything You Need

Professional-grade backtesting powered by artificial intelligence

Natural Language Input

Describe your strategy in plain English, with any indicator combination — RSI, ADX, VWAP bands, whatever you need. The AI understands and builds it.

Pine Script Support

Already have a TradingView strategy? Paste your Pine Script directly — the AI translates it to Python and runs the backtest automatically.

AI Code Generation

The LLM writes production-quality Python backtesting code with proper position sizing, risk management, and indicator calculations.

Portfolio Backtesting

Backtest multiple symbols at once — equal-weight or divided-capital allocation across your whole watchlist, with one combined equity curve and metrics.

Options Backtesting

Price real option positions against historical data with deterministic Black-Scholes valuation — for both equities (yfinance) and crypto (Deribit).

Interactive Charts

Professional candlestick charts with indicator overlays, equity curves, drawdown analysis, and trade markers — all interactive.

Monte Carlo Simulation

Test strategy robustness with randomized trade sequences. Understand worst-case scenarios and confidence intervals for your returns.

Walk-Forward Analysis

Validate your strategy with out-of-sample testing. Split data into train/test windows to detect overfitting before it costs you money.

Rich Data Support

50+ data columns including funding rates, open interest, liquidations, CVD, and more. Crypto and stock data supported via ccxt and yfinance.

Parameter Optimization

Grid search across parameter ranges to find optimal settings. The AI generates and executes the optimization code automatically.

Full Analytics Suite

Daily, weekly, or monthly breakdowns — returns heatmap, cumulative PnL, rolling Sharpe, Calmar ratio, consecutive streaks, trade duration, and more.

How It Works

From idea to analysis in three simple steps

Describe Your Strategy

Type your trading idea in plain English or paste Pine Script. For example: "Buy when the 10-period EMA crosses above the 50-period EMA with RSI below 70. Exit when RSI goes above 80 or price drops 3% from entry."

AI Generates & Executes

The LLM parses your strategy, generates optimized Python code, validates it for safety, and runs the backtest against your data — all in seconds. You can see the generated code and modify it.

Analyze Results

Get a complete analysis: interactive price chart with trades, equity curve, metrics dashboard, returns heatmap, Monte Carlo simulation, walk-forward validation, and AI-written insights — across single assets, multi-symbol portfolios, or options.

4. AI-Generated Code
The Software uses AI to generate backtesting code. While we strive for accuracy, AI-generated code may contain errors or produce incorrect results. Always review generated code and verify results before making any trading decisions.

5. Data Accuracy
Market data is sourced from third-party providers (ccxt, yfinance). We do not guarantee the accuracy, completeness, or timeliness of any data. Data may contain gaps, errors, or delays.

7. Privacy
Your strategy descriptions, generated code, backtest results, and market data stay on your own machine — we never see or store them. Creating an account does store a small amount of data on our server: your email address, a securely hashed (never plaintext) password, the devices you've registered, and your subscription/usage status, used solely to run your account and enforce plan limits.

Risk Disclaimer

Trading involves substantial risk of loss and is not suitable for all investors.

Backtested results are hypothetical and do not represent actual trading. There are numerous factors related to the markets in general which cannot be fully accounted for in backtesting:

Slippage and execution delays
Market impact of your orders
Liquidity constraints
Exchange outages and technical failures
Regulatory changes
Black swan events

Never trade with money you cannot afford to lose. Always do your own research and consult with a qualified financial advisor before making investment decisions.
