How it works
Mayer Multiple = current price ÷ 200-day moving average
Worked example
BTC at $65,000 with a $52,000 200DMA is a 1.25 multiple, inside the normal band. The same price against a $25,000 average would read 2.6, historically frothy.
FAQ
Where do I get the 200DMA?
Any charting site: add a 200-day simple moving average to the daily chart and read the current value.
Is 2.4 a sell signal?
It is a historical observation, not a rule. Multiples stayed above 2.4 for months in strong bulls. Use it as context, not a trigger.
