I see incorrect field ordering in the following JSON compact encoding messages:

Order from DTCProtocol.h:

    float BidPrice;
    float BidQuantity;
    float AskPrice;
    float AskQuantity;
    t_DateTime4Byte DateTime;
    uint32_t SymbolID;

Instead I'm seeing:

    uint32_t SymbolID;
    float BidPrice;
    float BidQuantity;
    float AskPrice;
    float AskQuantity;
    t_DateTime4Byte DateTime;
