From six tabs to one card: the C4Compare thesis

The average retail trader visits six or more websites before a single decision: charts on one, fundamentals on another, risk metrics somewhere else. The picture never comes together in one place. C4Compare collapses that ritual. Pick up to four instruments and see balance-sheet metrics, valuation ratios, risk indicators and a plain-language AI verdict side by side, in one card, in under a second. The calc engine runs on the NIAO runtime for sub-100ms client-side maths. Compare, Contrast, Conclude, Commit. This post covers the data pipeline and the risk model behind the cards.
