Java is at the core of many technologies, so it is no surprise that it also ranked among the most popular programming languages in a survey done by StackOverflow.
Many seasoned algo traders and novice quants use our Java API as it offers a great framework for building trading algos.
Today we will explore how to code Histograms in Java and submit the request via our award-winning trading platform.
It is important to note that histograms return data as a function of price level with function IBApi::EClient::reqHistogramData. Code along as shown in this example from our GitHub repository:
/*client.reqHistogramData(4004, ContractSamples.USStock(), false, “3 days”);
Next, let’s review how data is returned to IBApi::EWrapper::histogramData
@Override
public void histogramData(int reqId, List
System.out.println(EWrapperMsgGenerator.histogramData(reqId, items));
}
Finally, if you need to cancel a request for a histogram that has not retrieved any data, do so with this command:
IBApi::EClient::cancelHistogramData
