File formats for importing securities and security prices
Securities and security prices are imported in FA in semicolon-separated CSV files, with the file columns described below. You can import multiple entries (securities or security prices) at the same time with one file: each row of the CSV file is read as a separate object. However, you cannot import for example securities and prices to the system with the same file.
You can define the following properties of the CSV file in Preferences → Importing → File format (see Preference - Importing for details):
File delimiter. By default, FA is configured to accept semicolon-separated values. You can change it to another character.
Encoding: UTF-8 or Windows-1252. To import Scandinavian letters, the files should be Windows-1252 encoded in order to guarantee the appropriate handling of Scandinavian letters.

The columns of the file format are described below.
Updating securities
You can update existing securities or market price entries by importing a new file with corrected data.
The system identifies the security to update by the Security code. The market price entry to update is identified by the Security update code and the Market date, so you must fill in these fields. Additionally, you must fill in at least one of the following fields: Close, Accrual, Delta, Manual, or Close1 - Close5.
Note that you must specify if you want to keep the old values in each field:
To replace the field value, specify the new value in the import file.
To keep the existing field value saved in the system, add three stars *** in the field. Note: if you import an empty field without ***, the field value previously saved in the system is removed. For multi-value fields, you can import new values while keeping the old ones using three stars (***), for example, ***<new value1>,<new value2>.
Note
You can also update existing securities with #6 Security ISIN code if the system cannot find a matching security with the security code from the system, but will find a security with the same ISIN code. In such a scenario, the security code will also be updated.
Removing security values with three minuses (---)
You can remove individual values from multi-value fields by marking them with three minuses (---) in the CSV file. Currently, this syntax can be used for tags and profiles (tags and profileAttributes fields). Specify Security code in column 1. Add the fields you want to remove prefixed with three minuses (---). If you edit the CSV file in MS Excel, you need to put an apostrophe in the beginning of the column. For example: '---<tag_name_1>.
To remove multiple values, divide them with a comma for tags, and with a hash (#) for profile attributes. For example: ---<tag_name_1>,---<tag_name_2> or ---<profile attribute>#---<profile attribute>.
You can remove certain values and add other ones, for example: --<tag name 1>,<tag name 2> or ---<profile attribute>#<profile attribute>.

FA Format for importing security prices
# | Code | Required | Name | Description |
1 | pr.updateCode | Yes | Security update code | Code used to identify the security in the system. Securities can be identified with update codes, code, ISIN code or trade code (see below for more details). |
2 | pr.marketDate | Yes | Market date | yyyy-MM-dd |
3 | pr.close | No | Close price | Close price. When you define a close price, the system will determine which "Close" field the price will be store in (see below for more details). You can instead use a specific "Close" field to import a price directly to that field. For bonds, unit price can be set with % (e.g. 3.45%), when the system calculates the price according to YTM automatically. |
4 | pr.currency | No | Currency | Currency of the security (optional, used to identify the security if there are two securities with the same ISIN-code but different currency). |
5 | pr.accrual | No | Accrual | Price to be stored in "Accrual". (Available from FA 3.7 onward) |
6 | pr.delta | No | Delta | Price to be stored in "Delta". (Available from FA 3.7 onward) |
7 | pr.closeMan | No | Manual | Price to be stored as "Manual". (Available from FA 3.7 onward) |
8 | pr.close1 | No | Close 1 | Price to be stored as "Close 1". (Available from FA 3.7 onward) |
9 | pr.close2 | No | Close 2 | Price to be stored as "Close 2". (Available from FA 3.7 onward) |
10 | pr.close3 | No | Close 3 | Price to be stored as "Close 3". (Available from FA 3.7 onward) |
11 | pr.close4 | No | Close 4 | Price to be stored as "Close 4". (Available from FA 3.7 onward) |
12 | pr.close5 | No | Close 5 | Price to be stored as "Close 5". (Available from FA 3.7 onward) |
Which "update code" is used to identify securities (pr.mode)
When importing security prices through the update menu, you can select "Load by format" - this selection determines what security information the code in first column in your import file is mapped against to find a matching security.
Default (code LOAD_BY_DEFAULT) – identify the security primarily by using "Update code" (1, 2 or 3). If no matching security is found, then use the logic in "update by ISIN" (using "ISIN code" + currency if given), or if no unique security is still found, then use the login in "update by code" (using "Code").
Update by code (code LOAD_BY_CODE) - identify the security primarily by using "ISIN code", or if no unique security is found, then by using "Code".
Update by ISIN (code LOAD_BY_ISIN) - identify the security by using "ISIN code" (and #4 Currency if defined in the import file - currency is used to identify the security if there are two securities with the same ISIN-code but different currency).
Update by trade code (code LOAD_BY_TRADE_CODE) - identify the security by using "Trade code".
When importing security prices programmatically, you can use code pr.mode with the above LOAD_BY codes to determine which logic to use to identify your securities with the code you provide in pr.updateCode (available from FA 3.7 onward).
Which "close" the close prices are imported to (pr.n)
When importing security prices through the update menu, first row of the market price file can define (code pr.n), which "close" the prices are imported to. Security can have manual and up to five different close prices, and you can import prices to "manual" and any of the "closes". In the first row of the file, a numeric value 0 indicates the market price entries within the file are imported to the "manual" field (available from FA 2.4 onward), and a numeric value 1 through 5 indicates which "close" the market price entries within the file are imported to. If no numeric value is defined, the prices are imported to "Close 1". When using the update codes to import your prices (selection "Default" in the Import window), then the numeric value on the first row of the file also indicates which "Update code" is used to identify the securities: a numeric value 1 through 3 uses the corresponding "Update code" to identify the security, and imports the prices to the corresponding close.
When importing security prices through auto import in the update menu, a numeric value other than number 1 through 5 in the first row indicates that prices are updated with security's ISIN code and are saved to Close 1 (only available in Auto import).
When importing security prices programmatically, you can use codes pr.n (for the entire import) or or.updateColumn (for each row, available from FA 3.7 onward) with a numeric value 0 (manual), 1, 2, 3, 4 or 5 to indicate which "close" field you want to store pr.close into.
