Overview
FIXEdge offers the set of Business Rules, which can be useful to determine message routing, session events, scripting, message modification, plug-in connection, histories management, automatic routing for some types of the messages. The Rules formation is defined by special syntax in the XML format that is described in this guide.
Configuring Business Rules
Business Rules are stored in ‘FixEdge/conf/BL_Config.xml’ file in XML format. This file is loaded into the memory during FIXEdge starting. The installation package contains the business layer configuration file with rules that allow to test the FIXEdge functionality, but it needs to be configured for client's business needs in accordance with the recommendations described in this section.The name of configuration file can be changed in ‘FIXEdge.properties’ file using ‘BusinessLayer.RoutingRules’ property. The XML formatting is described in ‘FIXEdge/conf/BusinessLayer.dtd’. Rules can be changed from FIXICC or by editing the file directly. They can also be reloaded immediately from FIXICC.
The following classes are defined for Business Rules:
- Routing rules – used to transform and route FIX messages to sessions, adaptors etc.
- Session events – used to handle events that are launched during execution: create session, destroy session etc.
The Business Rules XML file may contain the following auxiliary entities definitions that could be used in Business Rules:
- Plug-ins – objects that encapsulate field transformation algorithm
- Handlers – objects that encapsulate message handling algorithm
- Histories – objects that store data from the handled messages
- Routing strategies – objects that encapsulate algorithms of automatic message routing
All described above elements belong to the element <BusinessLayer>.
Loading XML rules from separate files
XML rules for Business Layer can be stored in separate files. Use the following configuration property:
BusinessLayer.RoutingRules = file1.xml, file2.xml, file3.xml,…etc to load the set of rules.
Note |
---|
Please note while configuring: each XML document must be a part of a single document. I.e. the first file must contain the standard header of XML file <?xml version="1.0" encoding="UTF-8"?> (or UTF-16). |
The certain rules will be loaded into Business Layer from documents, but within tags:
Code Block | ||
---|---|---|
| ||
<FixEdge> <BusinessLayer> <!—- the rules set... --> </BusinessLayer> </FixEdge> |
Code Block | ||
---|---|---|
| ||
<?xml version="1.0" encoding="UTF-8"?> (or UTF-16). <FixEdge> <BusinessLayer> |
Code Block | ||
---|---|---|
| ||
</BusinessLayer> </FixEdge> |
In this case the configuration property will look like this:
BusinessLayer.RoutingRules = BL_header.xml,…file1.xml, file2.xml,…,BL_tail.xml
Rules processing order
Due to the specifics of the Business Layer Configuration File more than one rule can be applied to message. It is also possible to route one message to multiple destinations or to the same destination multiple times.
There are several items to mention here:
- All rules are applied independently.
- Rules are not necessarily performed at the order specified in BL Configuration File. The order is not predefined.
- If a set of transformation rules is applied to the same message, each rule receives its own copy of the original message and is applied to it.
- Actions defined in the rule are applied in the specified order, except the cases listed below:
- If the rule contains sending instructions, they are triggered and prepared at the specified in BL xml file place but are performed (meaning sent) after all other actions from the <action> element, except DisconnectSession or TerminateSession session instructions. See Routing Rules and Session Events: Mixed rules for an example.
- If the rule contains a set of sending instructions, they are not necessarily performed (meaning sent) at the order specified in BL Configuration File. The order is not predefined.
- If the rule contains DisconnectSession or TerminateSession session instructions, they are performed at the very end, after all sending instructions.
Rule
<Rule> element has couple of attributes: “Enabled” and "Description". <Rule Enabled=”false”> disables rule parsing by Business Layer. By default the attribute value has a true value.
Each rule consists of:
- Source (required section)
- Condition (implied section)
- Action (required section)
Refer to Rule element article for detailed description.
Default Rule
<DefaultRule> element defines special type of rules, which contains section <Action> only. Executed if no other rule is applied. Located at the end of Business Layer Configuration file. Usually contains action <DoNothing/>.
Code Block | ||
---|---|---|
| ||
<FIXEdge> <BusinessLayer> <!-- ... --> <DefaultRule> <Action> <DoNothing/> </Action> </DefaultRule> </BusinessLayer> </FIXEdge> |
Session events
FIXEdge router provides the user with a possibility to establish a set of Business Rules that handles FIXEdge events:
- New session was created.
- Session was destroyed.
- Unable to route message to a specified target.
- Session level reject was received in response to the sent application message.
- Routing rule failed during execution.
- Source section may have <FixSession SenderCompID="" TargetCompID=""/> element to identify a session that launches an event.
- Source section may have <Client Name=""/> element to identify a client that launches an event.
- Source section of any event may have <Source Name=""/> attribute of source identifier that launches an event.
Refer to Session Events for detailed description.
Plug-ins
FIXEdge offers a flexible solution for modification of FIX message partial fields - Plugins. Plugins provide an open interface and can be written in any programming language that allows creating modules in Microsoft Windows DLL format. The custom Plugins mechanism can be used in case Business Layer’s built-in mechanisms and engines cannot perform a specified task. <Plugins> section is optional and may contain one or more <plugin> definitions. Plugin elementEach <Plugin> element has:
Usage: Rule's instructionModifyField refers to the defined plugin and executes plugin method for the routed message. |
Param element
Param element is used in the configuration file within <Plugin> and <Script> elements to define their parameters.
Attributes:
Name | Mandatory. Defines name of parameter |
Value | Optional. Defines parameter value by default |
Handlers
FIXEdge offers a flexible solution for FIX message processing - Handlers. Handlers provide an open interface and can be written in any programming language that allows creating modules in Microsoft Windows DLL format. The custom Handlers mechanism can be used in case Business Layer’s built-in mechanisms and engines cannot perform a specified task. FIXEdge loads Handlers only once: when it parses the business layer configuration file. Optional <DllHandlers> section may contain one or more <handler> definitions. Handler elementMandatory attributes:
Usage: HandlerAction action refers to the defined Handler and initiates message handling by a specified Handler. See part FIXEdge API for BL Handlers for details. |
Histories
FIXEdge offers a flexible solution for storing information that goes through the Business Layer of FIXEdge – Histories. The Business Layer supports the following types of Histories:
- ODBCHistory - allows storing information in the ODBC database
- SQLiteHistory - allows storing information in the SQLite database
- FileHistory - allows storing information in the persistent file-based storage
- MemoryHistory - allows storing information in the transient memory-based storage
Histories can be used in routing rules only when they are defined in the BL rules XML file. Each <History> element has the common attributes:
Name | Mandatory. Name of History used to refer to History from XML actions or JavaScript functions. | ||
StorageType | Mandatory. Defines the type of History. Valid values: ODBC | SQLite | File | Memory | ||
ClearTime | Optional. Defines when the everyday clear procedure is started. The format is HH:MM:SS. Clear procedure erases obsolete records. The ClearTime attribute must be set in the UTC timezone for ODBCHistory and MemoryHistory, and in the local timezone for FileHistory. | ||
ClearOnLoad |
Optional. Defines whether the ClearHistory procedure will be invoked on the History creation or BL rules reload. The ClearHistory procedure is not executed on the FileHistory creation if the time specified in the ClearTime attribute has passed. If the ExpireDateTime column is not created for the History, but the ClearOnLoad attribute is set to 'true', then this History will not be created. Valid values: true | false |
and the additional attributes depending on the History type.
The Business Layer of FIXEdge can be extended with the set of actions to work with defined Histories from XML rules and JavaScript.
The following XML actions are available:
- SaveToHistory – saves the data retrieved from the FIX message to History.
- ClearHistory – erases obsolete records from History.
The following JavaScript functions are defined:
- saveToHistory - saves data to History
- updateHistory- modifies existing fields in the History
- saveOrUpdate - saves data to Hostory if possible, otherwise modifies existing field in the History
- getFromHistory - locates a record in History by key and retrieves the value of the record field
- getRecordFromHistory - locates a record in History by key and returns it
- removeRecordFromHistory - locates a record in History by key and removes it
- removeRecordFromHistoryByCompositeKey - locates a record in History by composite key and removes it
ODBCHistory
Each ODBCHistory defines regulations of storage FIX message tags within the particular table of the ODBC database. ODBCHistory supports the following additional attributes:
- TableName - Mandatory. The name of a table in the database. History will be reflected in this table.

ExpireDateTime field
The ExpireDateTime field defines the timestamp since which the record will be considered expired. The expired records trigger the ClearHistory procedure which cleans up the history. The ClearHistory procedure is triggered automatically on FIXEdge startup.
Info | ||
---|---|---|
If the ClearTime attribute is set for the History but the expireDateTime column is not defined then the following ERROR message will be added to the log file during clearing:
|
Example:
Code Block | ||||
---|---|---|---|---|
| ||||
<Field ColumnName="TransactTime">ExpireDateTime</Field> |
Info | ||
---|---|---|
The ExpireDateTime field of the History is optional since FIXEdge 6.14.0 release. If the History was created without the ExpireDateTime field then records will be inserted/updated in it without the expireDateTime value. In such a case the WARN level record below will be logged:
|
SQLiteHistory

FileHistory
Each FileHistory defines regulations of storage FIX message tags within the particular file. FileHistory supports the following additional attributes:
- WorkingDirectory – Mandatory. Path to stored FileHistory files.
- StorageFileName – Mandatory. The name of the FileHistory storage file.
Both KeyFields and Fields XML elements define a set of tags. Tags within the KeyFields element are used as a record composite key.

Fields element
Contains a set of comma-separated FIX message tags.
MemoryHistory
MemoryHistory defines regulations of storage FIX message tags within the FIXEdge server memory. MemoryHistory does not require additional attributes.
Both KeyFields and Fields XML elements define a set of tags. Tags within the KeyFields attribute are used as a record composite key.
Example:
Code Block | ||||
---|---|---|---|---|
| ||||
//Defines history "SampleMemHistory" // The ClOrdID(11), SenderCompId(49) and TargetCompId(56) FIX tags used as a record composite key <History Name="SampleMemHistory" StorageType="Memory" ClearTime="22:00:00"> <KeyFields>11, 49, 56</KeyFields> <Fields>99,18,63,64,528,529,100</Fields> <Field>ExpireDateTime</Field> </History> |
Scripts
FIXEdge offers a flexible solution for routing and transferring of FIX messages that go through the Business Layer of FIXEdge and data manipulations. In addition to XML Rules, there are two ways to enhance the flexibility of message transferring and data manipulation. Those ways are scripting with Javascript and XSLT. The proper usage of this feature requires scripts written in one of the scripting languages and assigned to the Script instruction of Action section in a Business Rule.
The scripting subsystem gives the user the following advantages:
- Saves the time spent on business logic implementation
- Flexibility and simplicity of modification
- Does not cause significant losses in performance
You can find more details about Javascript and XSTL scripting here: BL Scripting with JavaScript and BL Scripting with XSLT
Note |
---|
In case of the JavaScript usage you can control the number of parallel scripts using the BusinessLayer.JS.ExecuteInParallel parameter. More detailed information about it is available here: FIX Engine parameters#BusinessLayer.JS.ExecuteInParallel |
Business Rule scripting with Javascript
It is enough to mention that the script is a “Javascript” in the Script tag, in order to run the script and perform the proper transformations.
FIXEdge Javascript act provides the user with all the standard Javascript features and functionality. In addition to this, it enables the user to use functions that provide access to FIX message inside data, allows manipulations with fields and groups as well as whole FIX messages.
Predefined FIX date formats:
- HHMMSSUtc for the UTC "HH:MM:SS" date format
- HHMMSSsssUtc for the UTC "HH:MM:SS.sss" date format
- YYYYMM for the "YYYYMM" date format
- YYYYMMDD for the"YYYYMMDD" date format
- YYYYMMWW for the"YYYYMMWW" date format, where WW - number of week "w1"..."w4"
- DATETIMEUtc for the UTC "YYYYMMDD-HH:MM:SS" date format
- DATETIMEsssUtc for the UTC "YYYYMMDD-HH:MM:SS.sss" date format
- YYYYMMDDLmd for the local market "YYYYMMDD" date format
A trivial example of a complete JS script for a Business Rule is given below:
Code Block | ||
---|---|---|
| ||
//take the value the 11th tag from the fix message and get the last 4 //characters from it //assign the new value for the tag 11 with format BBBBSSSSCCYYMMDD //where //BBBB - any 4 characters //SSSS - last 4 characters from the old value of field 11 //СС - century //YY- year //MM - month //DD - day field_11 = getStringField(11); if(field_11.length() < 4) return; last4 = field_11.slice(field_11.length() - 4); currDate = getCurrentDateStr(YYYYMMDDUtc); century = currDate.slice(1, 3); century++; result = "bbbb" + last4 + century + currDate.substr(3); setStringField(11, result); |
Refer to BL Scripting with JavaScript for details.
Error handling during script execution
In case of syntax error in script its execution will be terminated and failed. There is no way to handle syntax errors in script during script execution. The user is able to stop script execution using throw statement, the result in this case will be the same. The user must be able to verify and handle logical errors using verification functions (like isNaN, isGroupValid, etc) in condition statements.
Business Rule scripting with XSLT
When a more complicated operation than a standard Business Rule can offer is required for field transformation, the XSLT script action can be used. The user should specify a certain FIX Field [and Field Length] in the Script instruction. The rules processor will extract the field value, apply the specified transformation and assign the obtained result to the field.
XSLT Script instruction in the Action section of a Business Rule:
Code Block | ||
---|---|---|
| ||
<Script Language="XSLT" Field="213" LengthField="212" FileName="script1.xslt" > <Param Name="AcctParam">"JBDFLLC"</Param> </Script> |
This instruction causes the rule processor to get the value of FIX field 213, loads XSLT script from script1.xslt file, applies the transformation to the value passing AcctParam parameter there and assigns the resulting value to field 213.
LengthField attribute is optional. If it is specified the rule processor sets the length to the result. This attribute must be specified if the field has FIX type Raw Data.
The specification for XSLT can be found at W3C. Apache Xalan is used as internal XSLT processor.
Refer to BL Scripting with XSLT for details.
Default routing strategies
There are two forms of default routing:
- DeliverToStrategy
- OrderFlowStrategy
DeliverToStrategy
<DeliverToStrategy> element specifies the routing destination that has been specified beforehand inside the source FIX message.
The following properties of the element are required:
- Name – contains the name of element to identify in factory rules.
- TargetField – contains a tag number with routing destination. Actually, there may be tag 128 <DeliverToCompID>.
- SourceField – contains a tag number with FIX message source and provides the possible back way relation.
Code Block | ||
---|---|---|
| ||
<DeliverToStrategy Name="DeliverToStrategy115128" SourceField="115" TargetField="128"/> |
Note |
---|
Business Layer takes the value from tag 49 <Sender> in case SourceField tag is not found in FIX message or is not specified in a rule. The direction of message routing is defined by session name that is a pair of Source|Target (or Sender|Target when SourceField is not found). The session with a specified pair of Source|Target should be registered in FIXEdge, otherwise a message will be rejected. |
OrderFlowStrategy
<OrderFlowStrategy> element defines the orders flow to destination that can be found in the history of orders.
The following properties of element are required:
- Name – contains the name of element to identify in factory rules.
- History – contains the name of History element, where the order flow strategy will refer to specify the routing destination.
- DestinationField – contains a tag number with destination. For example, tag 100 <ExDestination>.
Code Block | ||
---|---|---|
| ||
<OrderFlowStrategy Name="OrderFlowStrategy100" History="Orders" DestinationField="100" /> |
Note |
---|
OrderFlow strategy defines the destination of FIX message routing by source identifier only. Session with source identifier that in the destination field should be registered in FIXEdge, otherwise an order will be rejected. |
History used in the OrderFlow strategy must contain the following required fields:
- key fields:
- ClOrdID(11)
- CrossID(548)
- ListID(66)
- common fields:
- SenderCompID(49)
- TargetCompID (56)
- OrdStatus (39)
- ‘DestinationField’ value should be specified in strategy description (default 100)
Below is the example of appropriate history definition:
Code Block | ||
---|---|---|
| ||
<History Name="Orders" StorageType="File" CacheRecords="5" ClearTime="23:50:00" WorkingDirectory="FixEdge1/log/" StorageFileName="BLHistory_Orders.log"> <KeyFields>11,548,66</KeyFields> <Fields>49,56,100,1,39,439,440,167</Fields> </History> |
