It is an open source logging library for AmiBroker. It has following features:

• Print logs into files
• Specify the log directory (via chart parameters)
• Specify the file name (via chart parameters)
• You also will get to save file with different formats (csv, log, txt)
• Logs will be written in columns and you can specify column delimiters (helps to easily study the file in Excel)
• Automatically creates a separate logging file for each symbol (in scanner mode)
• Automatically creates a separate logging file for each day
• Finally there is also a provision to enable/disable logs

The default logging path is: C:\Program Files\AmiBroker\Logs.

Note: If the framework experiences any errors due to file permission issues, then it will stop logging.

These functions are available in logs-util.afl. To use these functions, add following line at the top of your afl:

#include <logs-util.afl>
