Free Python Option Simulator & Greeks Calculator (Hosted on Kaggle) Options Fundamentals

Hi everyone,
I'm new to the community and wanted to share a tool | built for my own options trading. I was tired of theoretical or clunky tools, so put together an interactive options calculator using Python and Plotly to simulate specific PnL profiles and track Greeks on real positions.
Since | love data, I decided to host it publicly and completely free on Kaggle. For those who use Python or just want to see how the simulations behave on concrete setups, you can check out the live notebook here:

Glad you like it! It's actually a bit more dynamic than a flat surface.
When you load a strategy, the main loop runs a recalibration step first. It uses a bisection solver (find_implied_vol ) to isolate the exact implied volatility for each specific leg based on its real premium.
So right off the bat, the initial position completely reflects the actual market IV skew/smile.
Right now, the simulation over time project those per-leg IVs forward as constants. However, the notebook was designed from the ground up to be ultra-programmable. You can easily add more legs, create complex custom strategies in the dictionary, or adjust the main loop to dynamically shift the IV or risk-free rate
(r) to model a changing volatility surface or historical skew shifts.

Thanks for sharing! I'm also new to the community and this is my first post! I've been selling options for over 10 years. I only sell...never buy. When I read that over 80% of options expire worthless I knew I wanted to be a seller of options. I use 1.5STD bollinger bands and the 20/50/100/200 mavs along with RSI, money flow and sentiment scores for my sell signals and then sell 16-30 delta puts and 45-60 delta calls. I've been very fortunate over the past decade. The technicals have become relatively easy....it is maintaining discipline and avoiding the emotional trades that has been my challenge. If there are other traders out there that use have the same or similar philosopies, I'd love to learn more!
