.fsi.getTicks API
This page provides an overview of the .fsi.getTicks API.
Note
The .fsi. prefix refers to the namespace for the FSI Accelerator Library. All the available FSI APIs must be called using this namespaced syntax.
The .fsi.getTicks API is used for raw data extraction and preprocessing. It is intended to run on a Data Access Process and retrieve records from a configured database table using a specified dictionary of arguments.
The gw variable below is defined as an IPC connection to the Service Gateway. For example :insights-qe-gateway:5050 would connect to the query environment gateway within an insights namespace.

Tip
The gw variable below is defined as an IPC connection to the Service Gateway. For example `:insights-qe-gateway:5050 would connect to the query environment gateway within an insights namespace.

The fill parameter can be used to specify how the to handle null values. It takes a single symbol which can be one of \ null \ zero \ forward \ linear \ linearStep.
-
null- Replace empty values with nulls. -
zero- Replace null values with a 0 value of the appropriate type. -
forward- Replace null values with the previous non-null value. -
linear- Linear interpolation according to time column of table. -
linearStep- Linear interpolation according to row index.
The below example highlights the difference between how linear and linearStep fills work.

echo $DATA | jq -cr '.payload'temporality/slice
There are two types of temporality currently supported, and each determines the way the startTS and endTS arguments are interpreted. The default value is continuous and when specified, .fsi.getTicks returns a continuous chunk of data between the specified startTS and endTS arguments.
When a slice temporality is specified, the API returns data between the values specified in the slice argument, for each date within the startTS and endTS timestamp.
For example, if you request data between 02:00 and 04:00 for a three day period using a time slice, then the following data would be returned:
|

When using an inputTZ timezone that observes daylight savings time, the system cannot robustly handle attempts to select data specifically within the non-existent or repeated local hour.
For example, on the night in March in New York where the clock skips forward from 1:59 to 03:00, attempting to select a data bucket that begins or ends within those time values may result in unexpected data returning. Our tests confirm that a work-around is using a startTS/endTS value that wholly surrounds the problematic local time range, that is a range at least as wide as startTS=01:59 to endTS=03:00.
Similarly for example, on the night in November in New York where the clock repeats an hour going from 1:59 back to 01:00, attempting to select a data bucket that begins or ends within those time values may result in unexpected data returning. Our tests confirm that a work-around is using a startTS/endTS value that wholly surrounds the problematic local time range, that is a range at least as wide as startTS=00:59 to endTS=02:00.

Accepted inputs are plotOrderbookSnapshots, instrumentNames and orderbookUpdatesRefData.
plotOrderbookSnapshots is used to more easily view OrderbookSnapshot data on a dashboard:
-
Filters the OrderbookSnapshots table for the max row within the specified time range.
-
Using that snapshotd data, the following values are calculated:
-
Calculate values:
-
bestAsk = min askPrice
-
bestBid = max bidPrice
-
maxSize = max (bidSize;askSize)

spread = bestAsk - bestBid
-

When choosing instrumentNames or orderbookUpdatesRefData the ref argument must be used with a value of Instrument to be able to query the correct reference data.
Relevant COREREF and CROSSREF reference data files must also be ingested in order for this to work correctly. If no reference data is found, the original instrumentID field is displayed as the instrument name.
