Protobuf file outdated?

Hi, Are the protobuf files outdated? Reason I ask is because: (1) The protobuf file is a "V3" file, but apparently the protocol is a "v8" (not sure they should match, though); and (2) More importantly, I'm receiving messages with fields that are not defined on the proto file! In the proto file I got from Github, the message PositionUpdate has 11 fields: message PositionUpdate { int32 RequestID = 1; int32 TotalNumberMessages = 2; int32 MessageNumber = 3; string Symbol = 4; string Exchange = 5; double Quantity = 6; double AveragePrice = 7; string PositionIdentifier = 8; string TradeAccount = 9; uint32 NoPositions = 10; uint32 Unsolicited = 11; } However, I'm receiving a message fields tag 12 and 13: TotalNumberMessages: 1 MessageNumber: 1 Symbol: "ES-FOP-20190517-2810-P-GLOBEX-50-USD" Quantity: 3 AveragePrice: 27.111733333000004 TradeAccount: "XXXXXXX" Unsolicited: 1 /* 11 unknown bytes */ 12: 0 13: 0 Any ideas? |

I found a different proto file that has those 2 extra fields. It also contain a lot of other changes compared to the file on Github. http://dtcprotocol.org/DTC_Files/DTCProtocol.GPBV3.proto So it's safe to say that the file on Github is badly outdated. Anyways, problem solved. Hopefully this can help others. |

The protobuf file is a "V3" file, but apparently the protocol is a "v8" (not sure they should match, though) Version 3 refers to Google protocol buffers version 3. Version 8 refers to the DTC protocol version.
