Mayer Multiple
Bitcoin's spot price divided by its 200-day moving average. Below 1.0 = price below the long-run trend (historically a green light for accumulators). Above 2.4 = top territory.
How to read it
Price divided by the 200-day moving average. Below 1.0 you are buying under the long-run trend, the accumulation zone. Around 1.0 to 1.5 is trend-following territory. Above 2.4 price has run far ahead of trend and mean reversion historically follows. It is the simplest of the cycle signals and the easiest to verify yourself with nothing but a price chart.
On Galaxy Mind
Mayer is the second-heaviest Buying Gauge signal at 14%. Because it needs only price history, it is also the gauge's most outage-resistant input: when fancier on-chain feeds drop, Mayer usually keeps reporting.
Context
Trader Mayer popularized the multiple as a discipline tool: systematically buying below 1.0 and sitting on hands above 2.4 has historically beaten lump-sum timing attempts. As bitcoin matures the extremes compress, the 2.4 ceiling was hit routinely in 2013 and 2017 but only briefly since, which is worth remembering when waiting for textbook extremes.
