MesoSim and MesoLive Releases
View All TagsOur goal has always been to help traders and researchers build better strategies.
Over the past year, we’ve invested heavily in expanding our data coverage, improving backtesting functionality and speed, enabling AI‑driven research, and adding new brokers to MesoLive. These enhancements directly translate into better research outcomes for our users.
To sustain the pace of innovation, we’re adjusting our pricing on 8 December, 2025.
MesoSim v3.0 is the most significant update to our simulator since its launch.
It introduces two major modules — the Options Valuation Model and the Timing Module—alongside numerous enhancements for quantitative strategy development. The release also refines user experience with an integrated AI Agent and a Volatility Surface viewer, helping you iterate faster and build more accurate strategies.
This is an important milestone, please read on.
We’re excited to announce MesoLive v2.0, headlined by full TastyTrade brokerage support, enhanced Paper Trading capabilities, and stability/performance improvements across the stack.
MesoSim v2.13 and MesoLive v1.1 introduce three key enhancements for quantitative options research and execution:
GLD ETF options, 3D volatility surface visualization, and unrestricted paper trading.
Today we are releasing Merlin v1.4 and Q-API v1.4, introducing significant enhancements in our machine-learning-based strategy-optimization toolkit.
These additions address recurring challenges in options-trading research: non-linear relationships, feature redundancy, and scale differences—that can degrade model performance.
