MesoSim – DSL for Options Trading

Hello, I quit my engineering job in 2021 to fully focus on trading. After a year of limited success with stocks (algos floating around break-even) I started studying Options. It turned out that selling options (risk premia harvesting) is a sound approach for income generation. Back in the day there were no suitable automated backtesters to effectively study these trades, so I built one: I infused JSON with Lua to create a Job Definition which models how Options Traders build, adjust and hedge their positions. Fast forward to today, many retail traders and small hedge funds are using MesoSim…

What it does

In the maker’s words, at launch

Hello, I quit my engineering job in 2021 to fully focus on trading. After a year of limited success with stocks (algos floating around break-even) I started studying Options. It turned out that selling options (risk premia harvesting) is a sound approach for income generation. Back in the day there were no suitable automated backtesters to effectively study these trades, so I built one: I infused JSON with Lua to create a Job Definition which models how Options Traders build, adjust and hedge their positions. Fast forward to today, many retail traders and small hedge funds are using MesoSim on a daily basis. They executed over 120k backtests with strategies frequently reaching (and exceeding) Sharpe Ratio of 3. You can also try it after a free signup I'm doing my best to provide educational material via blog posts on public income trades, such as: - The weekend effect: https://blog.deltaray.io/the-weekend-effect - Volatility Hedged Theta Engine: https://blog.deltaray.io/volatility-hedged-theta-engine - NetZero Trade: https://blog.deltaray.io/netzero-trade - and more under our strategy library: https://github.com/deltaray-io/strategy-library As of today the live part is running as a private beta and targeting to fix the annoyances around these complex instruments. Tech details: The solution is created using C# with Blazor as I prefer not to touch JS or TS. When I started I knew very little about C#, and nothing about blazor and dotnet (I'm a linux person). I have no regret choosing these technologies. During the process I also fell in love with Lua, a language I'll definitely use in the future. Please check it out and let me know what you think. Thanks for your kind feedback!

    With a 9-5 job and 2 kids I have finally finished my first MVP2021 · ▲501

    Hello HN crowd. I worked on this project on weekends and evenings. I'm excited I made it into a presentable MVP, and it is so satisfying. I would like to get some honest feedback from this great community. I made https://freeoptionscreener.com/, to scratch a personal itch. I myself trade options as a hobby, and I didn't find a screener that satisfies my need to be able to explore raw options data freely and without preset constraints. So I made this app that allows playing with options market data and extract interesting opportunities. The techs used: - Laravel + Jquery +…

    I learned to code and built a crypto analytics platform2023 · tradingdigits.io · ▲108

    Hey everyone! I am an enthusiast trader and a year ago I had this idea to create a free-to-use website that would feature all the most essential tools that traders would use on a daily basis. So I learned to code and build it—I did everything including design, texts, code, and SEO—which took me 12 months to launch and a year and a half to make it look like it currently does. I was into marketing and design before, but I didn't know barely anything about coding. The website is built using Next.js, Tailwind CSS, and Typescript with Framer Motion animations and lots of APIs. I’m actively…

    I built a tool to find trading signals that aren't just random luckSep 2025 · hikaro.app · ▲9

    Hi HN, I'm a solo dev and for the last few months I've been building Hikaro, a tool to find statistically significant trading signals for [e.g., US equities, crypto, forex]. I built this to solve my own problem: I was tired of backtests that looked great on paper but failed in practice. Simple metrics like "win rate" can be misleading, so I wanted a way to quickly tell if a signal's performance was genuine or just noise. Hikaro ingests daily market data and runs statistical analysis on various trading signals. The goal is to surface signals with strong properties, like: Low p-value: Evidence…
