BL Scripting with JavaScript

Logging in JavaScript

Example Code

print (getCurrentDateStr(DATETIMEUtc));

Execution of this line results in the following record in the application log:

[NOTE]  20131023-08:28:53.651 [4320] [../FixEdge/conf/test.js] - JavaScript '../FixEdge/conf/test.js' output: 20131023-08:28:53

Operations with session

Example Code

startSession("StartByEvent")

Example Code

startSession("FIXEdge","SimpleClient")

Example Code

startSession("FIXEdge","SimpleClient","Q1")

Example Code

disconnectSession("DisconnectByEvent","Disconnect by message")

Example Code

disconnectSession("FIXEdge","SimpleClient","Disconnect by message")

Example Code

disconnectSession("FIXEdge","SimpleClient","Disconnect by message","Q1")

Example Code

terminateSession("TerminateByEvent","Terminate by message")

Example Code

terminateSession("FIXEdge","SimpleClient","Terminate by message")

Example Code

terminateSession("FIXEdge","SimpleClient","Q1","Terminate by message")

Please note:

1. The session will not be visible in FIXICC or manageable (start, disconnect, etc) from FIXICC/BL/JS/scheduler.
2. The termination and the disconnection occur with async way after rule completion. In case of fail <OnRuleFailEvent> will be called.

Operations with messages across BL rules

Example Code

setCtxKV("messageID","123")

The function sets the value to the key to transfer information about the message between different BL rules. If the function argument's type is not a string then the function throws an exception.

Example Code

var id = getCtxKV("messageID")

var id = getCtxKV("messageID","0")

The function gets the value of the key from another BL rule.

If the function argument's type is not a string then the function throws an exception.

If the default value is specified and there is a key stored in the context then the function returns the value stored for the key.

If the specified key is not stored in the context:

• If the default value is specified then the function returns the default value.
• If the default value is not specified then the function throws an exception.

Example Code

delCtxKV("messageID")

The function deletes the value of the key. If the function's argument type is not a string then the function throws an exception.

Operations with group fields

Example Code

hndl = getGroup(78);

isGroupValid(hndl)

Gets a handle on group 78 and tests whether handle 78 is valid

Example Code

hndl = getGroup(552);

isGroupValid(hndl);

hndl2 = getGroup(hndl, 0, 518);

isGroupValid(hndl2); 

if(hndl2 != hndl){

    setNumField(552, 4);

}

Gets a handle on group 552 and tests whether the handle 552 is valid

Gets a handle from the first record of 552 group on group 518 and tests whether the handle 518 is valid

If the group handles are not identical, then increase the number of group 552 elements up to 4

Example Code

hndl = getGroup(78);

isGroupValid(hndl);

removeField(hndl, 0, 79);

Gets handle on group 78 and tests whether the handle 78 is valid 

Removes tag 79 from group 78

Example Code

//see the example above 

Example Code 1 

setNumField(268, 200);
hndl = getGroup(268);

bulkSetStringField(hndl, 0, 269, '0', 100);
bulkSetStringField(hndl, 100, 269, '1', 100);

Example Code 2 

bid_qty_list = [10, 20, 30, 40, 50];
ask_qty_list = [11, 22, 33];

setNumField(268, bid_qty_list.length + ask_qty_list.length);
hndl = getGroup(268);

bulkSetStringField(hndl, 0, 271, bid_qty_list);

For entries 0 - 99 set tag 269 (MDEntryType) to '0' ('Bid')

For entries 100 - 199 set tag 269 (MDEntryType) to '1' ('offer')

This is equivalent to code:

for (var i = 0; i < 100; i++) {
setStringField(hndl, i, 269, '0');
}

for (var i = 100; i < 200; i++) {
setStringField(hndl, i, 269, '1');
}

Example 2

For entries 0-4, copy values from bid_qty_list, so that entry[i][271] = bid_qty_list[i]

For entries 5-7, copy values from ask_qty_list, so that entry[5+i][271] = ask_qty_list[i]

This is equivalent to code:

for (var i = 0; i < bid_qty_list.length; i++) {
  setStringField(hndl, i, 271, bid_qty_list[i]);
}

for (var i = 0; i < ask_qty_list.length; i++) {
  setStringField(hndl, bid_qty_list.length + i, 271, ask_qty_list[i]);
}

Example Code

bids = [ [0.1, 10], [0.2, 20], [0.3, 30], [0.4, 40], [0.5, 50] ] ;

asks = [ [1.1, 11], [2.2, 20], [3.3, 30] ] ;

setNumField(268, bid_qty_list.length + ask_qty_list.length);
hndl = getGroup(268);

bulkSetStringFieldMapped(hndl, 0, 270, bids, 0);
bulkSetStringFieldMapped(hndl, 0, 271, bids, 1);

bulkSetStringFieldMapped(hndl, bid_qty_list.length, 270, bids, 0);
bulkSetStringFieldMapped(hndl, bid_qty_list.length, 271, bids, 1);

For alternative source structure

bids = [ {"price": 0.1, "qty": 10}, 
         {"price": 0.2, "qty": 20},
         {"price": 0.3, "qty": 30},
         {"price": 0.4, "qty": 40}, 
         {"price": 0.5, "qty": 50}] ;

asks = [ {"price": 1.1, "qty": 11}, 
         {"price": 2.2, "qty": 22}, 
         {"price": 3.3, "qty": 33}] ;

setNumField(268, bid_qty_list.length + ask_qty_list.length);
hndl = getGroup(268);

bulkSetStringFieldMapped(hndl, 0, 270, bids, 'price');
bulkSetStringFieldMapped(hndl, 0, 271, bids, 'qty');

bulkSetStringFieldMapped(hndl, bid_qty_list.length, 270, bids, 'price');
bulkSetStringFieldMapped(hndl, bid_qty_list.length, 271, bids, 'qty');

For entries 0-4, copy Price(270) and Size(271) values from bids;

For entries 5-7, copy Price(270) and Size(271) values from asks.

This is equivalent to code:

for (var i = 0; i < bid_qty_list.length; i++) {
bid = bid_qty_list[i];
setStringField(hndl, i, 270, bid[0]);
setStringField(hndl, i, 271, bid[1]);
}

for (var i = 0; i < ask_qty_list.length; i++) {
ask = ask_qty_list[i];
setStringField(noMDEntries, bid_qty_list.length + i, 270, ask[0]);
setStringField(noMDEntries, bid_qty_list.length + i, 271, ask[1]);
}

For alternative source structure

for (var i = 0; i < bid_qty_list.length; i++) {
  bid = bid_qty_list[i];
  setStringField(hndl, i, 270, bid['price']);
  setStringField(hndl, i, 271, bid['qty']);
}

for (var i = 0; i < ask_qty_list.length; i++) {
  ask = ask_qty_list[i];
  setStringField(noMDEntries, bid_qty_list.length + i, 270, ask['price']);
  setStringField(noMDEntries, bid_qty_list.length + i, 271, ask['qty']);
}

And remove it from the message.

Example Code

partiesGrp = getGroup(448);
if ( isGroupValid(partiesGrp) && isSupportedField(partiesGrp, 2376) )

Note: only default routing strategies can be used for processing: 
deliveryToStrategy, OrderFlowStrategy and WheelOrderFlowStrategy.

Example Code

strategyReject("orders", true);

Rejects a message that was stored by some strategy in the ‘orders’ history. Creates ‘j’ Business Reject when message rejecting has failed.

Notes: The method is used only in the default routing. Searching in history processes by the ‘ClOrdID’ key in the original message if its type: ‘D’, ‘AB’ or by ‘OrigClOrdID’ key in original message if its type: ‘AC’, ‘F’, ‘G’. 
Inapplicable for other messages.

Example Code

msg = serializeMessage();

Example Code

msg = serializeMessage("|");

Parses a message from the specified string and replaces the current message with it.

Error Handling Functions

Example Code:

setStringField(58, "Error (" + getErrorCode() + ") " + getErrorText());

This example assigns the values 'error code' and 'error text' to field 58.

As a result of this function, the content of tag 58 inside the FIX message could be, for example,: "Error (500) Internal server error"

Example Code:

setStringField(58, "Error (" + getErrorCode() + ") " + getErrorText());

This example assigns the values 'error code' and 'error text' to field 58.

As a result of this function, the content of tag 58 inside the FIX message could be, for example,: "Error (500) Internal server error"

History functions

Example Code:

key = new Array("snd","tgt");
time = getFromHistory("orders", key, "ExpireDateTime"); 
        

Returns the ‘20121221-10:52:00’ value from the record with key (snd,tgt) that has been updated by the previous sample.

Notes: the column which is created by the <expireDateTime> parameter always has the “ExpireDateTime” name in history. 
Other columns have names as described in the history description in BL_Config.xml or as a tag number in string representation if the column name is absent in the history description.

Example Code:

key = new Array("snd","tgt");
record = getRecordFromHistory("orders", key);
print(record); 

Returns a fields array of the record with the key (snd,tgt), then prints content into a log. 
The result will show “snd, tgt, ClOrdID, dest2, 20121221-10:52:00” if the record (snd, tgt) has been saved and updated by previous samples.

Notes: Empty fields have NULL values and printing represents it as “<null>”.
If <keyFields> is composite, then all fields in the key set should be filled.

Example Code:

key = new Array("snd","tgt");

removeRecordFromHistory("orders", key);  

Removes a record with a key (snd, tgt) from the ‘orders’ history.

Notes: If <keyFields> is composite, then all fields in the key set should be filled.

Example Code:

key = new Array("snd","");

ndeleted = removeRecordFromHistoryByCompositeKey ("orders", key);

Removes all records with keys which have first the “snd” field in a key.

Notes: the composite <keyFields> set should contain at least one field. All empty fields in a key will be ignored in searching.

Example Code:

encryptedPass = getStringField("554");
pass = decryptString(encryptedPass);

Example Code:

hash = hashString("MyPassword");

Getting hash for the "MyPassword" string.

Note: string for calculating hash should be not "null".
