})

const trkdClient = new TRKDClient()
trkdClient.quotes.retrieveItem('AAPL.O').then(quote => {
  console.log(quote)
})

Catalog

The trkdClient object shape is modeled after the TRKD catalog with method names matching those within TRKD.

Fundamentals

trkdClient.fundamentals.getSnapshotReports(companyId, companyIdType = 'RIC')

Quotes

trkdClient.quotes.retrieveItem(ric, fields = null)

Search

trkdClient.search.all(queries = Query.all, filters = {}, header = Query.header)

trkdClient.search.derivativeQuote(queries = Query.derivativeQuote, filters = {}, header = Query.header)

trkdClient.search.equityQuote(queries = Query.equityQuote, filters = {}, header = Query.header)

trkdClient.search.fundQuote(queries = Query.fundQuote, filters = {}, header = Query.header)

trkdClient.search.governmentAndCorporateBondInstruments(queries = Query.bondInstrument, filters = {}, header = Query.header)

Street Events

trkdClient.streetEvents.getEventHeadlines(eventType, startDate, endDate)

trkdClient.streetEvents.getEvent(eventId)

Time Series

trkdClient.timeseries.getIntraday(ric, startTime, endTime, interval)

trkdClient.timeseries.getInterday(ric, startTime, endTime, interval)

trkdClient.timeseries.getExchangeData(ric)

trkdClient.timeseries.getTimezone()

Search Queries and Filters

Values may be booleans, strings, or objects. Booleans and strings are constructed into appropriate query objects, whereas objects are passed in as is.

Examples:

{
  AssetCategory: true
}

becomes:

{
  AssetCategory: {
    Include: true
  }
}

---

{
  ExchangeCode: 'NSQ'
}

becomes:

{
  ExchangeCode: {
    Include: true,
    StringValue: [{
      Value: 'NSQ'
    }]
  }
}

---

{
  ExchangeCode: '!NSQ'
}

becomes:

{
  ExchangeCode: {
    Include: true,
    StringValue: [{
      Value: 'NSQ',
      Negated: true
    }]
  }
}

---

{
  MaturityDate: {
    Include: true,
    DateValue: [{
      Expression: 'GreaterThan',
      Value: new Date()
    }]
  }
}

has no change

Init Options

Name	Default	type	Notes
application	null	string	trkd provided
username	null	string	trkd provided
password	null	string	trkd provided
redisConnection	null	object	redis or ioredis connection
format	true	boolean	format responses into proper json

Caching and Limiting

A redis connection may be passed in the init options. Currently a redis or ioredis may be used. To be used you must set the expiration times (in seconds) per method or group as well.

TRKDClient.expiration.quotes.retrieveItem = 5
TRKDClient.expiration.timeSeries = {
  getIntraday: 60, // one minute
  getInterday: 60 * 60 * 24, // one day
  getExchangeData: 60 * 60 * 24 * 7, // one week
  getTimezone: 60 * 60 * 24 * 30, // one month
}

TR has rate limits on every route. It is recommended to use a rate limiter like bottleneck.
