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
