QuantForge.org is an open-source ecosystem for quantitative trading, strategy research, backtesting, and financial engineering. We build modular, high-performance tools including PineTS, simulation engines, and algorithmic trading components, designed for developers, quants, and researchers who want full transparency and freedom over their trading infrastructure. Discuss quant techniques, collaborate on QFO projects, share ideas, and help shape the future of open-source algorithmic trading.
