BTC: Log-Quote MACD Daily - Signal

Bitcoin Log-Quote MACD Daily - Signal was -0.0143 log ratio on 7 Nov 2026 (latest daily value).

The signal line: a 9-observation EMA of the daily log-price main line, itself the 12-observation minus 26-observation EMA of natural-log BTC price.

Why use it. Provide a slower companion to the main momentum line; their difference forms the histogram. How to read it. When the main line is above the signal the histogram is positive, and below it negative. The signal shares the main line's linear log-ratio scale, not a dollar spread; the BTC quote uses its own USD scale. It seeds only from valid main-line values, and gaps reset it. Daily sampling differs from the hourly method. Points are UTC days labelled at the day start, the open day a labelled partial; values are provisional and revisable. These are price comparisons, not forecasts.

Calculation. Signal = EMA9 of (EMA12 - EMA26 of the natural log of positive admitted daily closing quotes). Each EMA seeds with the arithmetic mean of its first N adjacent valid values, then uses alpha = 2/(N+1); gaps reset the state. State runs over the full contiguous history with 40-digit decimal arithmetic, and source revisions can change results.
