One engine for backtest and live, backed by 2,000+ automated tests, with walk-forward overfit checks.
Scenarios run on our servers, recover automatically after restarts, and alert you by email or Telegram.

*Arrow Algo is a strategy-building tool, not a financial advisor. Trading involves risk of loss, and past backtest results don’t guarantee future performance. Market data freshness varies by provider (for example, US stock data may be delayed). Our servers, exchanges and data providers can experience downtime or delays, and live fills can differ from simulations during fast markets or unexpected events. AI assistants can make mistakes, so verify outputs before trading.
Why not just ask a general AI?
Your AI never sees your exchange API keys. They are stored encrypted and used only by the engine.
Every strategy is backtested on years of data and checked on data it has never seen.
Strategies run on our servers 24/7, so your strategy keeps going even if your AI goes quiet.
Fixed rules behave the same way every time, so you can test them and trust them.
How it works
Assemble your strategy from visual blocks — or describe it to Artemis, the AI copilot, and watch it build. Plug in your own AI agents via MCP. No code required.
Test it instantly against live historical data straight from the exchanges — before you risk any capital.
Run your strategy 24/7 with automated execution by your chosen exchange. You stay in control.
Start with an idea
Buy when the 14-period RSI drops below 30 and sell when it rises above 70, on the 1-hour chart.
Test my moving-average crossover: the 50-day above the 200-day on the daily chart.
Here is my TradingView Pine Script. Turn it into a strategy I can backtest.
See it in action
A quick tour of the platform — what it does, how it works, and how to get started.
Features
Build your own strategies from 120+ indicators, conditions and actions with a drag-and-drop block builder — no programming knowledge required.
Tell Arrow the market, asset, timeframe, and risk style you want to explore, and turn an idea into a testable strategy.
Backtest on the exchanges' own historical data — no datasets to source or maintain. Then optimize parameters and risk rules before capital is at stake.
Trade across stocks, ETFs, crypto, futures, FX and more. Your funds stay with your exchange — an API key is all you need.
Plug your own AI agents — like Claude — into Arrow Algo via MCP, and let them build, backtest and run strategies from your own tools and terminals.
Run your strategies around the clock with automated execution. Your funds stay with your exchange — you stay in control.
Walk-forward testing
A strategy tuned to one stretch of history can fall apart on data it has never seen. Optimize parameters, then validate on unseen data to detect overfitting — Arrow Algo scores every walk-forward run with an Overfitting Risk rating.
Get started
No code. No datasets to manage. Backtest and run demo strategies before you risk a penny.
