See the motivation inside this post.

On March 18, 2026, we are releasing MesoSim v3.1. This update includes more than 30 improvements and fixes across four areas:

• AI enablement
• Mobile usability
• American options modeling
• Multi-timeframe support

The headline feature in this release is the direct integration of the MesoSim AI Assistant into MesoSim Portal.

Trading options can be an effective way to generate income and grow a portfolio, but results depend on process quality: disciplined research, repeatable execution, and risk controls that hold up in live markets.

Historically, MesoLive operated with a "human in the loop". With the MesoLive SDK, our customers can automate execution while keeping the controls and oversight their operation requires.

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.
