① A “△” in the field indicates a space of the character code.
② The mandatory attributes of the FIX tag are described as follows.
　　　　◎ : Mandatory for the FIX message
　　　　〇 : Not Mandatory for the FIX message but mandatory for CONNEQTOR
　　　　□ : Conditionally mandatory

③ Price set/output methods for each trading
　 The format of price set/output is ZZZZZZZ9. 9999. Specifically, it is as follows.

④ Unless stated specifically, all field values are set according to the definition in 2.2 Data Types.

• Example1: When the field is defined as “Int” and values range from '0' to '100', setting to '0' will be |0|, and setting to '100' will be |100|.
  
• Example2: When the field is defined as “Char” and values range from '△△1' to '100', setting to '△△1' will be|△△1|, setting to '100' will be |100|.
  

⑤ Dummy values
　When stated “dummy value(s)” in the data format tables, the system checks the format/range of those field values but ignores appropriateness between fields.

⑥ Description for Standard Header of Messages
　The “Standard Header” description for each message includes the following information: 1) TAG35:MsgType value for that message and 2) “conditionally mandatory” tag values for the Standard Header (refer to 2.5 Standard Header).

⑦ Order quantity set for each trading
　Set on a per share basis. (e.g. when placing an order for 1,000 shares, set Tag38 to 1000.)

A FIX message consists of a standard header, message body and a standard trailer as shown below.

* Each message consists of a series of fields, each of them is represented as a combination of the tag number and the value (tag number=value) and separated (or terminated) by a delimiter, i.e. ASCII “SOH” (#001).
　　For example, a FIX message starts with “8=FIX.4.2” and ends with “10=nnn<SOH>”, like this:
　　8=FIX.4.2<SOH>9=60<SOH>35=A<SOH> . . . (omitted) . .
* The following tags are discarded as invalid.
　　Any tag other than tags defined by each message in CONNEQTOR
　　Any Standard Header tag that exists in the Body or Standard Trailer
　　Any Body tag that exists in the Standard Trailer

　● Message integrity assurance
　　The integrity of message data content is confirmed in two ways: 1) verification of message length (Tag=9: BodyLength) and 2) verification of checksum of characters (Tag=10: CheckSum).
　　If it is not possible to assure the integrity of a message, it is discarded as an invalid message.

Data Type represents the type of the value defined for each tag. The following table shows data types in use.

For a message that contains valid data as a FIX message, the message format is checked in accordance with the rules of the FIX Protocol Specification (Ver4.2Errata).
Check items are as follows.

• Existence of mandatory tags (mandatory as FIX protocol)
  
• Existence of conditionally mandatory tags (mandatory as FIX protocol)
  
• Conformance with the type of data
  
• Range check (the setting value must be within the range defined in the FIX protocol)
  

When a message not compliant with any of the above rules is received, a Reject shall be sent to the other party’s system to notify the message of the format error.

Described in Annex 1 "Standard Message Header/Trailer Format".

Described in Annex 2 "Administrative Message Format".

※ The legend for the required fields is as follows:
