Q: What is Vertex Street?

Vertex Street is an AI-powered backtesting platform that lets you test any trading strategy through natural language conversation using real historical market data.

Q: Why not just ask ChatGPT?

We actually encourage it. The difference is the sandbox. A real backtest requires real data and real computation. General AI can describe a strategy, but it struggles to run one. Vertex Street uses AI to orchestrate the entire environment: writing the backtest, executing it in a sandbox, and returning results you can actually trust.

Q: What markets and indicators are supported?

Vertex Street supports stocks, ETFs, crypto, and forex with technical indicators including RSI, MACD, Bollinger Bands, moving averages, and more. Historical data goes back 20+ years for major assets.

Q: How much does it cost?

Start with a $1 trial (3 days, 15 turns). Then continue on Core at $24.99/month, or $249.90/year with two months free (200 turns/month). Each turn is one message in a backtest conversation.

Q: Is this financial advice?

No. Vertex Street is a research and education tool. Backtest results are based on historical data and do not guarantee future performance. Always do your own research before making investment decisions.

Q: Can I share my backtest results?

Yes. You can share any backtest result as a public post. Shared posts appear on your profile and have a chance to be featured on the trending page, where the community discovers top-performing strategies.

Combine price history, 30+ technical indicators, candlestick patterns, financial statements, and macro data like GDP and CPI in a single strategy through your own words.

Buy SPY when RSI(14) drops below 30, sell all when RSI crosses above 70

Standard RSI mean-reversion setup on SPY, 3 years of daily data by default. Buys $1,000 chunks whenever RSI(14) closes below 30, exits the full position when RSI crosses back above 70. Since SPY rarely gets deeply oversold, expect this to fire infrequently — most of RSI<30 episodes on a broad index ETF cluster around sharp selloffs (think August 2024, early April 2025 tariff shock). That's actually the interesting part: this strategy is really a bet on "buy the panic, sell the recovery," and its trade count will tell you how rare true panic dips have been over the period versus how much of SPY's return came from just holding through the grind higher.

Watch the win rate against buy-and-hold return in the results — on an index this diversified, a low-frequency dip-buy strategy often underperforms simply holding, because SPY spends most of its time trending up and RSI<30 signals are lagging indicators of a bottom, not leading ones. The alpha/beta stats will show whether the timing added anything over passive exposure.
