Expected Output

Actual Output

109 |   | BLAH

The structure of FIX messages is such that nested structures are represented flattened in the parent. Their boundaries are not self-describing, and additional metadata about the format is required.

Header fields appear at the beginning of the message.

From Wikipedia:

Up to FIX.4.4, the header contained three fields: 8 (BeginString), 9 (BodyLength), and 35 (MsgType) tags.

From FIXT.1.1 / FIX.5.0, the header contains five mandatory fields and one optional field: 8 (BeginString), 9 (BodyLength), 35 (MsgType), 49 (SenderCompID), 56 (TargetCompID) and 1128 (ApplVerID - if present must be in 6th position).

Further, messages which do not contain a valid header should be identified as erroneous.

Seeing general conversation on "doesn't support field NNN" always returns to this, fix-decoder should support the current standard.

• Dump FIX 5 fields onto the end of data.js as a fig-leaf
• Add capability for multiple (vanilla) dictionaries with version-detection

Have a input that, when edited, shows matching fields/message types/etc.

Hello,

I am not a js expert. i am trying to build fix-decoder but when I run gulp I have the next error:

gulp[14802]: ../src/node_contextify.cc:635:static void node::contextify::ContextifyScript::New(const v8::FunctionCallbackInfo<v8::Value>&): Assertion `args[1]->IsString()' failed.

Tag 22 shows the description (ISIN Number in below example) alongside the actual value (4 in the below example)

22 | SecurityIDSource | ISIN Number (4)

However, Tag 456, which uses the same dictionary as 22 https://www.onixs.biz/fix-dictionary/4.4/tagNum_456.html does not show the description, just the value (1 in the below example, when CUSIP (1) was the expected outcome)

456 | SecurityAltIDSource | 1

Currently the app uses a single set for all field IDs. Investigate whether we need a different mapping for each FIX version.

Include the descriptions of fields as tool tips or similar.

• Invalid BeginString
• Field value doesn't match expected type
• Checksum invalid
• Incorrect body length

Hi,

This is a nice tool, we modified the regexpr to allow ^A and tabular separators

I know it only breaks on ^, it works, so I guess you only keep digits for the fixtags part later on in the code

Tabs are little bit pointless as putty gives away spaces when copy pasting from it, but I guess some people use them for readability as we do, but I am not 100% sure they won't be used in the fix values

Expected Output

1057 | AggressorIndicator | BLAH

Actual Output

1057 | | BLAH

Valid dictionary values of BLAH are

'Y' | Order initiator is aggressor
'N' | Order initiator is passive

It can be convenient to send a message to someone else for review. The page's hash fragment should be updated (provided it's not too long) with an encoded version of the message text. Possibly use Base64 encoding.
