This chart places Bitcoin price alongside EMA 21, EMA 50, EMA 200, SMA 20, SMA 50, SMA 100, SMA 200, and Bollinger Bands (20,2). The moving averages provide short- and long-term trend context, while the Bollinger Bands provide volatility context. Together, they show where spot sits relative to trend.
The moving averages cover several widely watched crossover relationships. These include the canonical 1D SMA 50/200 Golden Cross and Death Cross, the BTC-specific 1W EMA 21/EMA 50 crossover, and the 1W SMA 50/100 crossover historically associated with Bitcoin bear-market bottoms. Historical intersections are marked on the chart with vertical lines when an active crossover pair is available.
The left axis has three optional views, with only one shown at a time. BB Width tracks volatility through the relative width of the Bollinger Bands. Higher values mean wider bands and higher volatility; lower values mean tighter bands and lower volatility. Dev vs SMA200 measures the percentage distance between price and SMA200. A value of +20% means price is 20% above SMA200; -20% means it is 20% below.
Z vs SMA200 expresses the same price-to-SMA200 gap in units of the 365-period rolling standard deviation of price. A Z value of +1 means the gap above SMA200 equals one rolling standard deviation; -1 means the same-sized gap below it. Larger absolute Z values indicate a larger deviation relative to the price variability in that window. Periods follow the selected chart resolution. All three optional views can be turned off.
Because these indicators are derived from the same market-price series, agreement between them is not independent confirmation.
