What is an RSI heatmap?
RSI stands for Relative Strength Index. It compares the gains and losses of the last 14 candles and turns them into a number from 0 to 100. Above 70 is usually called overbought, below 30 oversold, and 50 is the line between buyers and sellers.
The RSI heatmap puts the RSI of hundreds of coins on one chart and sorts them into five zones: overbought, strong, neutral, weak and oversold. At a glance you see whether the whole market is running hot or cold, which coins are leading and which are falling behind.
Overbought does not mean an immediate drop: in a strong market RSI can stay above 70 for a long time. The heatmap is best for judging overall sentiment and comparing relative strength; entries and exits still come from each coin’s own chart.
An example: BTC’s 4-hour RSI is 58, still neutral, while most altcoins are already above 70 and the market average is 69.6. The market is clearly running hot, and chasing a breakout now carries more risk than usual.
