Pi Cycle Bitcoin Top Indicator

The script implements the Pi Cycle Top indicator

This indicator identifies tops in the bitcoin market cycle. Historically, the Pi Cycle Top indicator has called out tops in the price of bitcoin within three days.

The script is very easy to use and it is possible to change the following parameters:

• the time interval (default value is day);
  
• the days of long moving average (default value is 365)
  
• the days of short moving average (default value is 111)
  
• show the moving average plots
  
• show the Pi Cycle Top label highlighting the cross-point
  

Notes de version:

Improved the management of the graph timeframe.

Now the script automatically use the timeframe of the graph.

Notes de version:

Show (with a label) when the long MA crossed above the short MA (named Pi cycle down).

Added two alert conditions:
1) Pi cycle top;
2) when the long MA crossed above the short MA.
