What is pinestack?

Pinestack is a toolkit built around a separate project called piner, which is an engine that runs Pine Script, the scripting language TradingView uses for indicators and trading strategies. Normally Pine Script only runs inside TradingView's own charts, tied to one symbol and one timeframe at a time. Pinestack takes the piner engine and wraps it so you can run it outside of TradingView, across many symbols and settings at once, from the command line or your own scripts. With pinestack you can scan a single indicator or strategy across hundreds of trading symbols at the same time, backtest a strategy and get a full report on its performance, and sweep through many parameter combinations to see how a strategy behaves under each one. The main way to use it is a command line tool called pinerun, which is distributed as a single downloadable program with everything already built in, so there is nothing extra like Node or a package manager to install first. It supports Linux, macOS, and Windows. The project is organized as two packages. One, called pinery, is the data layer that fetches historical price data from sources like Binance, OKX, Kraken, and Alpaca, and also supports loading your own CSV files. The other, pinerun, is the orchestration layer that manages running jobs, fans work out across many symbols or parameter combinations, and includes the CLI itself. Both packages depend on the piner engine, which stays a separate, lightweight library. To get started, you scaffold a starter trading strategy file with one command, then run a backtest on that strategy against real market data, for example five hundred hours of Bitcoin price history, with another command. The tool then prints a detailed report showing returns, risk metrics like maximum drawdown and volatility, and charts of price, account equity, and drawdown, all directly in the terminal. Running the project from source requires the Bun JavaScript runtime, version 1.2 or newer. The project is licensed under the AGPL version 3 license, a copyleft license that requires anyone who modifies and distributes the code, including running it as a network service, to also share their source code.
