XTesterDevelop and backtest trading strategies
XTester Launcher · On your server: Paper or HyperLiquid Testnet, not Mainnet. Run on your own server →
Open a strategy, choose historical data and run a backtest. Review its trades, equity and drawdown.
From code to trades
Write code, download history and review test results in XTester Studio. Open a trade, locate it on the chart and check which rule triggered it.
AI helps adapt code from a file, folder or Git repository. After conversion, compare trades with the original strategy: execution rules can differ between platforms.
Compare strategy versions
Use AI Lab to refine a strategy and compare versions by trades, returns and drawdown. Testing several strategies on a shared account is planned and is not part of alpha.4.
Strategy languages
C# has the fullest support, including AI Lab. Python, JavaScript, TypeScript, Java, Go, C++, Rust and R use experimental adapters, and available features differ. Pine Script support covers a subset of the language and uses XTester’s interpreter.
