You instantly see the theoretical premium, all five Greeks — Delta, Gamma, Theta, Vega, and Rho — and an interactive profit-and-loss chart showing how the position performs across a range of stock prices, both at expiration and today. It supports long calls, long puts, covered calls, and cash-secured puts, with breakevens, maximum profit, and maximum loss calculated for you. The calculator works with both US and Canadian stocks, and there is no signup, no login, and no paywall on any of the core tools. Yes.

  Hi HN! I’m a solo founder who trades options, and I got tired of paying $100–$300/month for a bunch of different tools: one for GEX, one for backtesting, one for scanning, another for trade ideas, another for volatility… it felt like death by a thousand subscriptions. So I built a single website that replaces all of them and made it completely free. For anyone who trades options, it’s basically all your favorite money making tools in one place, with a super generous free tier so that you never need to pay unless you’re a crazy power user.

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
