Configuring QuickFIX

A quickfix acceptor or initiator can maintain multiple FIX sessions. A FIX session is defined in QuickFIX as a unique combination of a BeginString (the FIX version number), a SenderCompID (your ID), and a TargetCompID (the ID of your counterparty). A SessionQualifier can also be use to disambiguate otherwise identical sessions.

The SessionSettings class has the ability to pull settings out of any c++ stream such as a file stream. You can also pass it a filename. If you decide to write your own components, (storage for a particular database, a new kind of connector etc...), you can also use this pass in settings.

A settings file is set up with two types of headings, a [DEFAULT] and a [SESSION] heading. [SESSION] tells QuickFIX that a new Session is being defined. [DEFAULT] is a where you can define settings that all sessions use by default. If you do not provide a setting that QuickFIX needs, it will throw a ConfigError telling you what setting is missing or improperly formatted.

ConnectionType Defines if session will act as an acceptor or an initiator initiator
acceptor
StartTime Time of day that this FIX session becomes activated time in the format of HH:MM:SS, time is represented in UTC
EndTime Time of day that this FIX session becomes deactivated time in the format of HH:MM:SS, time is represented in UTC
StartDay For week long sessions, the starting day of week for the session. Use in combination with StartTime. Day of week in English using any abbreviation (i.e. mo, mon, mond, monda, monday are all valid)
EndDay For week long sessions, the ending day of week for the session. Use in combination with EndTime. Day of week in English using any abbreviation (i.e. mo, mon, mond, monda, monday are all valid)
UseLocalTime Indicates StartTime and EndTime are expressed in localtime instead of UTC. Times in messages will still be set to UTC as this is required by the FIX specifications. Y

MillisecondsInTimeStamp Determines if milliseconds should be added to timestamps. Only available for FIX.4.2 and greater. Y
N
Y
SendRedundantResendRequests If set to Y, QuickFIX will send all necessary resend requests, even if they appear redundant. Some systems will not certify the engine unless it does this. When set to N, QuickFIX will attempt to minimize resend requests. This is particularly useful on high volume systems. Y
N
N
ResetOnLogon Determines if sequence numbers should be reset when recieving a logon request. Acceptors only. Y

N
ResetOnLogout Determines if sequence numbers should be reset to 1 after a normal logout termination. Y
N
N
ResetOnDisconnect Determines if sequence numbers should be reset to 1 after an abnormal termination. Y

N
RefreshOnLogon Determines if session state should be restored from persistence layer when logging on. Useful for creating hot failover sessions. Y

Validation
UseDataDictionary Tell session whether or not to expect a data dictionary. You should always use a DataDictionary if you are using repeating groups. Y

DataDictionary XML definition file for validating incoming FIX messages. If no DataDictionary is supplied, only basic message validation will be done

This setting should only be used with FIX transport versions older than FIXT.1.1. See TransportDataDictionary and AppDataDictionary for FIXT.1.1 settings.
valid XML data dictionary file, QuickFIX comes with the following defaults in the spec directory

FIX44.xml
FIX43.xml
FIX42.xml
FIX41.xml
FIX40.xml
TransportDataDictionary XML definition file for validating admin (transport) messages. This setting is only valid for FIXT.1.1 (or newer) sessions.

See DataDictionary for older transport versions (FIX.4.0 - FIX.4.4) for additional information.
valid XML data dictionary file, QuickFIX comes with the following defaults in the spec directory

FIXT1.1.xml
AppDataDictionary XML definition file for validating application messages. This setting is only valid for FIXT.1.1 (or newer) sessions.

See DataDictionary for older transport versions (FIX.4.0 - FIX.4.4) for additional information.

This setting supports the possibility of a custom application data dictionary for each session. This setting would only be used with FIXT 1.1 and new transport protocols. This setting can be used as a prefix to specify multiple application dictionaries for the FIXT transport. For example:
DefaultApplVerID=FIX.4.2
# For default application version ID
AppDataDictionary=FIX42.xml
# For nondefault application version ID
# Use BeginString suffix for app version
AppDataDictionary.FIX.4.4=FIX44.xml

ValidateLengthAndChecksum If set to N, messages with incorrect length or checksum fields will not be rejected. You can also use this to force acceptance of repeating groups without a data dictionary. In this scenario you will not be able to access all repeating groups. Y
N
Y
ValidateFieldsOutOfOrder If set to N, fields that are out of order (i.e. body fields in the header, or header fields in the body) will not be rejected. Useful for connecting to systems which do not properly order fields. Y
N
Y
ValidateFieldsHaveValues If set to N, fields without values (empty) will not be rejected. Useful for connecting to systems which improperly send empty tags. Y
N
Y
ValidateUserDefinedFields If set to N, user defined fields will not be rejected if they are not defined in the data dictionary, or are present in messages they do not belong to. Y
N
Y
CheckCompID If set to Y, messages must be received from the counterparty with the correct SenderCompID and TargetCompID. Some systems will send you different CompIDs by design, so you must set this to N. Y
N
Y
CheckLatency If set to Y, messages must be received from the counterparty within a defined number of seconds (see MaxLatency). It is useful to turn this off if a system uses localtime for it's timestamps instead of GMT. Y
