The Pi Cycle Top indicator compares two moving averages of the Bitcoin price: the 111-day and twice the 350-day. When the 111DMA rises through 2×350DMA the lines cross; in past cycles that happened within days of the market top. The chart shows both lines over the daily closing price on a log scale.
On 28 Sep 2026 the 111-day moving average of Bitcoin is $69,365 and twice the 350-day moving average is $156,717. The 111DMA would have to rise 125.9% relative to 2×350DMA to cross it; in past cycles the cross came within days of the price top. The last cross in this data was on 12 Apr 2021, at $59,860.

Pi Cycle Top FAQ
What is the Pi Cycle Top indicator?
An indicator created by Philip Swift in 2019. It plots the 111-day moving average of the Bitcoin price and twice the 350-day moving average. 350 ÷ 111 is close to π, hence the name. When the faster 111DMA rises above 2×350DMA, the lines cross.
What happened after past crosses?
The cross came within about three days of the cycle tops of 2013, December 2017 and April 2021. It did not fire at the November 2021 high, which came after a second rally. After a cross the lines can stay crossed for weeks.
How is the distance to a cross calculated?
As how far the 111-day average would have to rise, relative to twice the 350-day average, to meet it: 2×350DMA ÷ 111DMA − 1. Both averages use daily closes in UTC.
Where does the price data come from?
Daily closing prices (00:00 UTC) of Bitcoin from exchange public APIs: Binance spot BTCUSDT from 17 Aug 2017. Moving averages start once enough days of history have passed. The data refreshes every few hours, and today's close is the latest price so far. Each chart's data is free to download as CSV.
Is this a buy or sell signal?
No. These indicators describe how the price moved against its own averages in past cycles, and Bitcoin has had only a handful of cycles, so any pattern rests on very few examples. Nothing here is financial advice.
