Bitcoin's 120-day exponential moving average of the daily close.

Why use it. A slow trend line that follows the medium-term trend, weighting recent days more. How to read it. Price above it means a medium-term uptrend, below it a downtrend.

Calculation. Exact definition: The 120-day exponential moving average of the admitted daily closing BTC/USD quote. The EMA lags the quote: a quote above the line is above its smoothed level, and below it beneath. The EMA is seeded from its first 120 adjacent daily values and resets at gaps, so a missing quote restarts the warmup. Day D uses the following 00:00 UTC quote; earlier quotes are retrospective closes with unknown publication time, venue and vintage, later ones keep their actual clocks, values are provisional and revisable, and the open day is a labelled partial. ema(a if a > 0, otherwise undefined, 120): a 120-day exponential moving average of each UTC day's positive admitted ending-boundary BTC/USD quote, seeded with its first 120 adjacent values and reset at gaps, with no carry or interpolation. Computed over the full retained history before viewport selection, with existing 40-digit Decimal arithmetic.
