Put the NGX heatmap on your site.
Every Nigerian ticker, sized by market cap, coloured by move — rendered from the NGX daily close. Paste one iframe tag; it stays current on its own. Read-only, cached, and it carries a small “Powered by Vantis Terminal” credit.

<iframe src="https://vantisterminal.com/embed/heatmap" width="640" height="420" style="border:0;max-width:100%" loading="lazy" title="NGX market heatmap — Vantis Terminal"></iframe>Resize the width/height attributes freely — the image scales to fit. Prices are daily closes, not live quotes.
