Show HN: Educational Options Calculator

Hi HN,

I'm a software developer who's been actively trading options for the past few years. I found myself wanting a tool that made it easier to visually analyze positiong instead of looking at just tables and numbers, so I started building my own tool.

My site is an education-focused web app for building options strategies and exploring them with interactive, 3D P/L charts and heatmaps. The goal is to help students understand some of the more complex options trades with a focus on multi-leg strategies.

I'd love any feedback on the UX, visualizations, or features you'd find useful. This is currently a POC of sorts so I'm looking to nail down which parts would be most helpful to students. I've included the kitchen sink of visualizations but my personal favorite is the 3D Analysis under 3D P/L Surface (Price × Time). I don't see this visual on many sites so I'd love to build one that makes sense, visually.

For the time being I've hosted it on the same domain as my main project, https://www.olelohonua.com (i18n translation tool).

Thanks for checking it out!
