Hi @hiteshk81

To retrieve Open Interest data you can use the below formula in Python. It retrieves a sample time series for a Light Crude Oil front month future contract.

 ek.get_data('LCOc1', ['TR.OPENINTEREST.Date', 'TR.OPENINTEREST'], {'SDate':'2019-05-01','EDate':'2019-05-06'})

More information about Eikon Data API, tutorials and samples you can find here.

Thank you, can we use this Eikon API without the Eikon Desktop tool running in the background ?

For instance a https request to Eikon API using python flask or some other REST interface ?

or to extract Open Interests Data, do we need the Eikon Desktop Tool and the Credentials as mandatory things ? and is this the only way to do it ?

thanks you in advance

@hiteshk81
To use Eikon APIs you need to have Eikon account credentials and you need to run Eikon application. We have other products that could provide the data you're looking for and that may be a better fit for purpose depending on the use case.
