MesoSim Review, Pricing, and Features

Free tier available

MesoSim is an options strategy backtesting platform for traders who need low-code strategy definitions, multi-leg simulations, risk graphs, Greeks, volatility surfaces, margin models, and paper/live workflow paths. It is narrow by design: options research first, not broad stock research or portfolio accounting.

Key features

  • Backtest options strategies through a low-code Strategy Definition workflow covering entries, exits, adjustments, fills, commissions, slippage, margin, and monitoring.
  • Simulate documented instruments such as SPX, BTCUSD, ETHUSD, and higher-tier RUT, VIX, and GLD options where plan access supports them.
  • Review 2D and 3D risk graphs, PnL, Greeks, and trace collection from the Position Monitor.
  • Explore implied volatility surfaces with overlays such as open interest, volume, bid-ask spread, and Greeks where available.
  • Use Black-Scholes-Merton valuation functions and solver tools inside strategy logic for projecting future Greeks, PnL, roots, and optimization points.
  • Track margin at position and account level when margin reporting is enabled.
  • Export event logs or blotter data as compressed JSON for custom post-processing and analytics.
  • Use strategy templates, AI-assisted strategy development, and result sharing to speed up iteration on multi-leg options ideas.
  • Plan around access: API and institutional automation are FundPro-only, while retail plans focus on web backtesting, paper trading accounts, and MesoLive add-ons.
  • Treat MesoSim as options backtesting and simulation software, not a broker, broad equity terminal, tax/accounting system, or guaranteed trading edge.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
