Welcome to Vertex Street

Vertex Street is an AI-powered backtesting platform that answers your investment questions using real historical market data. Describe what you want to test in plain English — the AI handles the rest.

What can you do?

a. Run a full buy/sell backtest strategy

Describe your entry and exit conditions and Vertex Street will simulate the strategy against real market data. You get a complete portfolio breakdown — total return, win rate, max drawdown, every trade logged with dates and prices.

Buy SPY when RSI drops below 30, sell when it crosses above 70. Start with $10,000 over the last 5 years.

b. Ask how often an event occurs

Curious how often the S&P 500 drops 3 days in a row? Or how frequently a stock trades below its 200-day moving average? Just ask. Vertex Street scans historical data and gives you a concrete answer with dates, counts, and context.

How often has Apple fallen more than 5% in a single week over the last 10 years?

c. Get data-driven answers about the market

Ask anything about stocks, fundamentals, or macro indicators. Vertex Street pulls from income statements, balance sheets, key metrics, economic data, and more — then answers with the numbers to back it up.

What was Tesla's revenue growth rate each year for the last 5 years?

How it works

You type a question or strategy in natural language. The AI interprets your intent, fetches the relevant financial data, writes and executes a backtest in a sandboxed environment, and returns the results — all in one conversation turn.

No code required. No spreadsheets. Just ask and get results you can trust, backed by real data.
