🍌 I built "Banana Screener" - A free Streamlit app to help smooth brains avoid IV Crush and find the best GME Options Opportunities 🦍 🦧
With all the options talk lately, I wanted to build a tool that actually helps retail level the playing field without needing a finance degree. Options chains on standard brokers are built to confuse you and market makers love it when we overpay for hype or get robbed on wide bid/ask spreads.
So, I built the Banana Screener. It’s a free, live web dashboard that pulls options data and translates the Greeks into plain English. It is specifically designed to help you analyze risk, track volatility, and plan your exits.
Here is what it does:
- 🦍 Ape Mode vs. 🦧 Orangutan (Pro) Mode: A toggle at the top right switches the entire UI. Ape mode hides the confusing jargon and tells you exactly what a metric means in plain English. Pro mode unlocks all the raw data for the wrinkle brains.
- 🚨 Live IV Crush Alerts: The app automatically compares a contract's Implied Volatility (the hype) against the stock's 1-year Historical Volatility. If options are overpriced, it flashes a big red warning so you don't buy the top of a volatility spike and lose money even if the stock goes up.
- 🎯 Automated Exit Planner (GTC): The P&L Sandbox includes a target profit slider that instantly calculates the exact price you should set your Good-Til-Canceled (GTC) limit sell order at. Best practice is to set it immediately after buying so you don't get greedy and miss the exit. (I like to set GTC orders to sell half my position at 100% gain as a fail safe)
- 🛡️ Regard-Proof Filters: Hardcoded sliders let you filter out contracts with massive bid/ask spreads, low volume, or insane extrinsic premiums so you aren't paying purely for hype.
- 🌊 Volatility Skew Maps: For the Orangutans, there are interactive Plotly charts mapping out contract cheapness and volatility skew.
I built this for the community to use. There are no ads, no paywalls, and no sign-ups. The default ticker is GME, but you can plug in anything you want to watch.
Test it out on desktop or mobile and let me know what you think or if there are any features you want added!
Standard Disclaimer: I am highly regarded and eat green crayons for breakfast. This is a tool for educational purposes and is absolutely not financial advice. Options are risky as hell, but somebody's gotta build that gamma ramp!! 🚀
