Weekly MACD

In plain English

MACD is two moving averages of price, subtracted, then compared with a slower “signal” line. The histogram is the gap between them: fat green means upside momentum is expanding; fat red means it is fading.

This version is computed on the log of weekly price so 2014’s swings and 2026’s swings share a scale. Early spikes are hidden while the averages warm up.

Math and metrics

MACD 12/26/9 on weekly ln(price). Optional faint daily MACD only when median sample gap ≤2 days. Warm-up of 34 bars nulled.

MACD = EMA_12(ln P) − EMA_26(ln P). signal = EMA_9(MACD). hist = MACD − signal.

Log transform is so early-cycle dollar vol does not dominate the pane. Not a valuation.
