Current Issues

This web page is to keep everyone informed of  important issues in ANNI or currently known bugs along with their work arounds or estimated time it will be fixed.

If you have a bug that is not shown below, first and foremost...make sure you have the latest versions installed by checking via the supplied Auto Updater. If you are not up-to-date, update ANNI first, then recheck to see if the problem still occurs. If it does, please report it immediately to Support so the problem can be handled as quickly as possible.

Important Issues:

v3.21.2

Improvement/Maintenance Release:

Feature Improvements/Modifications:

  • Added support for data files with YYYY/M/D date format and where date and time fields are combined into a single column

     
  • Improved Advanced Trade System's training speed


The following bugs have been fixed in this version:

  • Brokerage Ratings Analysis and Earnings Analysis were causing ANNI to crash within a few minutes after starting caused by a recent change to the web pages that ANNI retrieves this information from

     
  • Brokerage Ratings Analysis and Earnings Analysis were not allowing multiple selections to be added to the Portfolio simultaneously

     
  • Trade System's views were using incorrect equity values

     
  • Creation of files using standard Trade System resulted in random crashes

     
  • Opening an ANNI file from the Windows Explorer window resulted in a crash

     
  • Fixed broken links in help file

     
  • Training icon wasn't updating correctly in various views

v3.20.1

Improvement/Maintenance Release:

Feature Improvements/Modifications:

  • Key options are now exposed for the Trade System providing significant customization capabilities.

     
  • Advanced Trade System utilizes 32 inputs (vs. 7 originally) one of which is the output from the proprietary volatility analysis algorithm. New network topology significantly reduced the impact this would normally have on training.

     
  • Modified the Trade System's data segment selector algorithm to 'randomly' concentrate on areas the system doesn't do as well on. This causes the Trade System to produce very robust signals that are applicable to a wider range of market conditions then before (i.e. the system is producing better global solutions rather then strong local solutions).

     
  • Training time for each system now reflects actual CPU time rather then straight time.

     
  • Minimum screen size requirement was changed from 640x480 to 800x600 allowing several views to become uncongested.

     
  • Ability to select multiple stocks simultaneously from various tool views to add all at once to your Portfolio.

The following bugs have been fixed in this version:

  • Adding investments from the tools view could cause ANNI to crash

     
  • Moving the mouse wheel after selection from a drop down box causes other selections to quickly get selected and processed. This in turn caused either the previous results to get replaced or sometimes a crash to occur for views that have intensive calculations to perform.
v3.19.0

Maintenance Release:

The following bugs have been fixed in this version:

  • Incorrectly computed buy/hold return % for evaluation and test data segments

     
  • Genetically trained trade system not producing enough trades

 

Reported Bugs:

v3.21.2 No Issue Currently Reported

 

Other:
