This indicator is a based on "200 Week Moving Average Heatmap" by Plan B. It shows "heatmap" of a security based on % increase of its 200 week (or other) moving average. It can be used for Bitcoin, as well identifying overheated Stocks (like TSLA). Plan B designed this indicator for Bitcoin using MA = 1400 (which is 200 trading days in Crypto), I personally found it useful to indicate overheated Stock Market stocks using MA = 250 (which is ~1 year of net trading days, excluding weekends and holidays).
Enjoy!
