RemarksA type 2 record is a 2-dimensional array where the type 2 index acts as a row-key and the field / value pairs are column keys / values. This type of record is often used to represent a level 2 order book for example:
| type2Index | BidSize | Bid | Ask | AskSize |
|---|---|---|---|---|
| ABN1 | 100 | 10.22 | 10.28 | 55 |
| ZBN2 | 200 | 10.20 | 20.33 | 250 |
| ARC | 1 | 10.16 | 10.41 | 1 |
The update is not represented in this same way. A single update will only ever be recieved for one type2Index. This type2index can be queried on the received event using Type2IndexField. The Fields then contains only data relating to the specific type2Index.
