About This Indicator

Realized Volatility measures how much BTC's price has actually swung, expressed as an annualized standard deviation of daily log returns over trailing 30-day and 90-day windows. Unlike the valuation-ratio charts elsewhere in this library, volatility is not directional — both cycle tops and capitulation bottoms show elevated readings. Its main use is spotting compression (unusually low volatility), which has historically preceded large moves in either direction.

  • BTC Liquidation HeatmapEstimates where leveraged BTC perpetual futures positions are likely to be liquidated. No free data source publishes real per-position liquidation prices — exchanges don't disclose them, and Coinglass-style heatmap APIs gate this behind a paid tier — so this is a disclosed model, not real liquidation data: it splits each day's total open interest across five assumed leverage tiers (5x-100x), treats the trailing 30 days of closing prices (recency-weighted) as a proxy for where positions were entered, and plots the resulting estimated liquidation prices as a density heatmap around price.
