Weekly MACD: Why It Earns the Second-Highest Weight in the Thermometer

Quick answer: Weekly MACD carries the second-highest single weight in the BTC Cycle Thermometer (15%, after mining cost) because it's the best trend-reversal confirmer among the nine: the high-level cross-down after the Nov-2021 top and the deep cross-up in the Dec-2022 bottom zone proved, in hindsight, the cleanest turn confirmations of the cycle. The thermometer normalizes it as DIF% = DIF ÷ price × 100 (absolute DIF differs 100x between 2017 and 2025): historic top zones ran ~+15-25%, bottoms ~-15-20%.

Why weekly

Daily MACD crosses dozens of times a year — pure noise; monthly signals arrive months late, after the move is mostly done. Weekly is the golden middle: only a handful of crosses per full cycle, each mapping to a real medium-term trend change. That's the value of a confirmation-type indicator — slow, but it doesn't lie.

Pairing with weekly RSI

The thermometer's momentum group pairs them: RSI warns early (it hit 90+ in April 2021, then diverged from price for half a year before the top), MACD confirms (the cross-down after the divergence is the action signal). Prepare on the RSI warning, act on the MACD confirmation — the two-stage combo beats either alone, which is why both stay in the ensemble sharing 15%+8%.

Three misreadings

One: shrinking histogram ≠ reversal (that's deceleration; no cross, no trend change). Two: trading crosses in a range (MACD is a trend tool; sideways crosses are chop). Three: ignoring divergence timeframe (weekly divergence has cycle meaning; daily divergence is just a swing). The live DIF% sits in the thermometer components — best used alongside the top checklist and bottom checklist.
