The Pi Cycle Top Indicator is a tool designed to identify potential price peaks (tops) in Bitcoin during bull markets. It uses two moving averages (MAs): a 111-day SMA and a 350-day SMA multiplied by a factor of 2. When the 111-SMA crosses above the 350-SMA (x2), it signals a potential market top. This is visually displayed on the chart with a symbol, such as a magnet icon, indicating a possible trend reversal. Historically, the indicator has been effective in predicting major Bitcoin cycle peaks and is widely used by experienced traders for market analysis.
