Requesting Histograms with Java API

Did you know that Java programming language was ranked # 1 by stackify.com in the “A Look At 5 of the Most Popular Programming Languages of 2019”?

If you are interested in building skills with this programming language, check out our award-wining Trader Workstation Java API. Today we will look at creating a histogram with the function reqHistogramData.

First, download the Testbed sample projects. This script provides ready-to use code for streaming market data, setting up scanners and error handling. Keep in mind that Java 8 or higher is required for running the Java API client.

Next, connect your custom algo script to our Trader Workstation.

Then review IBKR GitHub for sample code – follow these simple syntax steps to create your histogram.

/*client.reqHistogramData(4004, ContractSamples.USStock(), false, “3 days”);

@Override public void histogramData(int reqId, List<HistogramEntry> items) { System.out.println(EWrapperMsgGenerator.histogramData(reqId, items)); }

Finally, be sure to visit IBKR GitHub to learn how to cancel an active histogram or for other practical histogram functions.
