Creating Custom Data Files for ANNI to Use
Working with custom data files is more technical in nature for
someone trying to maximize ANNI's power. These steps can be intimidating to
the average user and should only be performed by someone familiar with what they
are doing.
- First create a regular file (this is to give you a
base data file to work with) for the stock you will train with.
- The data file will be located in a sub-directory
(called data) to where you saved the ANNI file to. It will be labeled with
the stock symbol and .csv - open this file and view the format.
- ANNI supports up to 5 columns of data (Close, High,
Low, Open and Volume). The closing column is the target value and must
always be available.
- Decide which of the remaining columns you will not
be using as direct inputs or as inputs to any technical indicators...for
example, don't change the Volume column if you use the "Price/Volume
Trend" indicator since you will effectively destroy this indicator once
you change the Volume column (note: the Open values are not used in any
indicators so this can be replaced without any adverse effects on indicator
calculations).
- Once you've decided which columns will be available
to you, using a spreadsheet program, copy and paste your custom data into
the appropriate column and save the file. Examples can be an Index,
Interest Rates, Custom Indicator created by you, another similar stock, etc.
IMPORTANT!!
ANNI does incremental updates, so it shouldn't overwrite existing column
data whenever you do an online update. But...every time you do an update,
you must remodify your custom columns new entries with the appropriate data
prior to continuing training or you will contaminate the net's weights with
incorrect information.
IMPORTANT!!
All custom values must be positive
numbers. No negative numbers should exist. If necessary, offset
your data by an amount necessary to make them all positive.
- If replacing columns other then the Open column, go into ANNI's Configurations dialog and select the
"Indicators" view. Unselect any conflicting indicators as
described in step 4, then go to the "Raw Data" tab and select the
columns which you have modified. Then select OK.
- At this point, ANNI will now be directly using your
custom supplied values in its training algorithm.
