The settings in this section describe only FIXEdge parameters. These parameters don't belong to FIX sessions parameters or FIX Engine parameters

These settings of the FIXEdge are defined into '' configuration file.

TCP Protection parameters

This section describes properties in file which are responsible for TCP protection.


The property enables TCP protection.

Valid values: true/false. Default value: ProtectionTCP.Enabled = false.

Example: ProtectionTCP.Enabled = true


The property to specify connection timeout (in milliseconds) of waiting for logon. When the time comes out, the connection is closed with corresponding reason:

[INFO]  20160706-07:40:53.032 [1274500] [Engine] - Logon message wasn't received in a given time interval(1000 ms) from
[INFO]  20160706-07:40:53.032 [1274500] [Engine] - Incoming TCP connection was closed (from

Disable when equal to 0. Default value: ProtectionTCP.WaitLogon = 10000


The property will be enabled only if ProtectionTCP.Enabled = true


The property to specify maximum of connections waiting for logon from one host. When the number of connections from the same host exceeds specified value of the property, new connections will be rejected with corresponding reason. 

[INFO]  20160706-07:30:21.566 [1271868] [Engine] - Incoming TCP connection was rejected (from Excedeed limit of connections (5) from a single host.

Disable when equal to 0. Default value: ProtectionTCP.SizeWaitHostMax = 5


The property will be enabled only if ProtectionTCP.Enabled = true


Specifies the maximum size (in bytes) of the buffer to be able to avoid the situation when user sends high-loaded garbage. 

When the limit is exceeded, connection will be closed and corresponding reason will be written to the log.

[INFO] 20160706-07:21:19.809 [1271256] [Engine] - Incoming TCP connection was detected (from
[INFO] 20160706-07:21:19.965 [1271896] [Engine] - Exceeded buffer received limited(1000000 ) from
[INFO] 20160706-07:21:19.966 [1271896] [Engine] - Incoming TCP connection was closed (from


When connection is re-established after closure, Client will send Logon message with MsgSeqNum = <last outgoing sequence number> + 1. As a result, FIXEdge will send ResendRequest and will receive the same message which caused disconnection. Thus, connection will be closed again.

The minimum size of the property which can be specified is 262144. If a lower value is specified in the property, it will be replaced with 262144 on the start of the FIXEdge.

If 0 is specified, there is no limit for the size of the buffer.

Default value: ProtectionTCP.SizeBufferMax = 0.


The property will be enabled only if ProtectionTCP.Enabled = true

For more information please read the article How to configure TCP protection in FIXEdge.

Transport Adaptors common parameters

The section contains fields which are common for all Transport Adaptors.


Valid values: true|false.

When the option is true, FIX Edge uses the latest Client's status in Status Notification message. When option is false, FIX Edge sends Client's status 'Terminated Correctly' in Status Notification message;

Default value is false.


Valid values: true|false.

When the option is true, Transport Layer allows to call onLogout() callback for the TA Clients without onLogon() call. When the option is false, Transport Layer ignores onLogout() callbacks for the client that didn't call onLogon() before.

Default value is false.

Control Centre parameters


XML Sock monitoring port to accept requests from the special tool FEAdminConsole.

Example: ControlCentre.XMLSockMonitor.Port = 8902


File that prevents from starting multiple FIXEdge instances at the same directory.

Example: ControlCentre.Lock.File.Name = FIXEdge1/log/_fixedge.lock

Starting several FIXEdge instances at the same directory will cause an error:

ERROR: Cannot create lock file '../FIXEdge1/log/_fixedge.lock'. Possibly another instance of the application is running using the same directory.

Settings of FIXICC Functionality Availability


Optional. Defines if the new schedule management functionality should be available in FIXICC or not.

  • If FIXICC.Schedules = true, new schedule management functionality is available in FIXICC
  • If FIXICC.Schedules = false or FIXICC.Schedules is not specified, new schedule management functionality is not available in FIXICC.

Default value: false.

Monitoring Memory Usage


Optional. Enable this parameter to force engine to monitor RAM capacity occupied by FIXEdge.

Once value is reached and exceeded FIXEdge generates OnNotificationEvent to notify about exceeding the available memory.

Value set in Mb.


Optional. Frequency of checking occupied memory.

Value set in seconds.

FIXEdge.MemoryWatch.Limit = 100
FIXEdge.MemoryWatch.Interval = 60

Described functionality is implemented in FIXEdge Windows version only.
