London, United Kingdom – July 15, 2025 – Quod Financial today announced the public release of QuantReplay, an open-source, multi-asset trading simulator designed to transform how trading teams test and validate strategies in today’s fragmented and fast-moving markets.
Originally developed for Quod Financial’s internal use, QuantReplay has been instrumental in supporting the firm’s strategy development and system validation. Now, Quod Financial is making this advanced simulator freely available to the global trading community, providing unprecedented access to institutional-grade tools for execution strategy testing.
Built for quants, researchers, and trading professionals, QuantReplay delivers a high-fidelity simulation environment that replicates the complexity and unpredictability of real-world electronic trading. Traditional simulators often fall short—limited in scope, realism, or asset class coverage—whereas QuantReplay raises the bar with an extensible, powerful platform that reflects the challenges of live execution.
“QuantReplay has been a critical component of our internal technology stack for years, enabling our teams to validate complex strategies in environments that mirror real market behavior,” said Medan Gabbay, Co-CEO of Quod Financial. “By making this technology open-source, we’re providing the broader trading community with the same high-performance simulation capabilities that we trust every day.”
QuantReplay supports a broad range of asset classes including equities, FX, futures, and digital assets, enabling users to backtest multi-asset strategies with precision. Its core features include:
- Historical data playback, for reconstructing real market scenarios.
- Synthetic order flow modeling, to simulate unpredictable market behavior and test strategies under varied liquidity and volatility conditions.
- Stochastic order generation, for simulating edge cases and stress conditions.
- A real-time simulation engine, capable of modeling auction periods, continuous trading, and other market phases.
By releasing QuantReplay as an open-source tool, Quod Financial aims to bridge the gap between institutional-grade simulation and public accessibility, making robust strategy testing available to a much broader audience.
QuantReplay is now live and open to contributions on GitHub. To explore, deploy, or contribute to the project, visit quantreplay.com or github.com/quodfinancial/quantreplay.
