Trade fee formulas use a simple language (a modified version of the PHP programming language) to specify how fees should be assessed in PropReports.
A "Per Execution" formula runs once for every "Regular" fill and the result is saved as the fee. The formula will NOT run for any fill that is either canceled, has fees manually set or has a status that is not regular.
Important: Make sure the Formula Type is set to "Per Execution" when creating a plan.
The following variables are available when creating a Per Execution formula:

$source | A numeric code indicating where the execution originated. See the list of source ids. |
$date | The trade date in YYYY-MM-DD format (e.g. 2011-08-15). |
