Get Quotes

Synopsis​

This operator communicates with Spring Financial server and gets a stream of real-time quotes of each input symbol.

Description​

This operator will connect and fetch real-time quotes from the Spring Financial Server for a list of input symbols. Symbols can be received from the Get Quote Symbols operator. The Get Quotes operator may need some time (at least a few seconds) as the streamed data comes from different sources. This operator outputs a collection of ExampleSets, each representing a list of real-time quotes for an input symbol(s). The order information for each quote is provided in the annotation. This provides the reference to the stock exchange and symbol, for which the quotes are retrieved. This operator is intended for examining and collecting data in RapidMiner. To use it as part of a streaming process, use Quote or Depth Stream operator.
