Why this matters
Volatility Surface Basics: Term Structure Explained is one of those subjects that sounds simple until you implement it, at which point the hidden complexity appears. The first version works on a laptop with a tiny file; the second version breaks at 3am when the WebSocket drops, the replay file is half-written, and you cannot tell which ticks you already stored. This article is a structural walkthrough: the concepts, the math where it helps, the code shape where it helps, and the failure modes that quietly cost money or correctness. No live market numbers are quoted because a number without a dated source is decoration, not education. The structure here does not expire, and unlike a specific price level, you can reuse it on the next dataset without re-deriving anything. If you only remember one sentence from this page, make it this: the boring parts are the product, and the interesting parts are a small fraction of what separates a demo from a system.
