RSI Heatmap Widget — Overbought & Oversold
See a whole market's momentum in one picture. The RSI heatmap plots every asset by its Relative Strength Index, colours it by zone — oversold green through overbought red — and lets readers switch between Crypto, Forex and Stocks and a 1H, 4H, 1D or 1W timeframe. Above the map, three cards summarise the market: the average RSI on a gauge, the share of names that are overbought versus oversold, and where RSI stood yesterday, a week ago and a month ago. The RSI comes straight from Vunelix's live oscillator feed — nothing is computed in the browser — and the widget drops into any site with no signup and no API key.

Read a Market's Momentum in One View
A single RSI number tells you about one asset; the heatmap tells you about the whole market. Each asset is a bubble placed on a 0–100 axis by its RSI, so a glance shows whether most of the market is stretched to the upside, sold off, or sitting in neutral. The zones are colour-coded the way traders expect — oversold at the bottom in green, overbought at the top in red — so the shape of the market reads instantly, without studying a table.
Crypto, Forex and Stocks
Switch between three markets with the tabs. Crypto covers the top coins, Forex the major and minor pairs plus gold and silver, and Stocks the most-traded names in any country — with a searchable country picker so you can point it at US, UK, German or any other market. Every market uses the same layout, so readers learn it once.
Summary Cards Above the Map
Three cards give the market's state in numbers. The average RSI sits on a gauge from oversold to overbought with a badge that names the zone. The overbought-versus-oversold card shows what share of assets is stretched each way. The historical card tracks the basket's average RSI yesterday, seven days ago and thirty days ago, so a reader sees whether momentum is building or fading.
