Eikon API timeseries time field in start and end date string

Is the time in the start_date and end_date parameter of the get_timeseries command used or do we only get end of day info? If intra-day info is available what time zone is the time defined in and what would we get for CLOSE field for example?

I played a bit with the numbers after the T delimiter in the command below and did not get any change in the retrieved info, the response always came back for T00:00:00.

> get_timeseries('IBM','*',start_date = '2017-03-21T17:00:00',end_date='2017-03-31T23:00:00','weekly')

TIMESTAMP HIGH CLOSE LOW OPEN COUNT VOLUME NA


1 2017-03-24T00:00:00Z 176.23 173.83 172.8 175.65 156607 16816029 IBM


2 2017-03-31T00:00:00Z 175 174.14 172.0937 172.69 130766 15950463 IBM

Any way to just get the date instead of the timestamp and "Security" instead of NA to reduce data formatting steps?

Thanks,

Claudiu

    Hi @claudiu thanks for your reply - I will check this - I can replicate your issue. One thing I would say is the the times are GMT so for a US stock you might need to take that into consideration. I think the request that generates the 1980-03-xx response is just plain wrong - your request errors when I hit the service directly as it should because you are requesting 1 hours data during a period that the market is not open - hence you should expect an error or no data available type message - it seems to be a problem with the way the R wrapper is handling this. I will check with @ahmed.mohammed and @iain.scott

    forgot to mention, using eikonapir package in R

    Hi @claudiu The interval you are requesting is Weekly (which is essentially Interday - rather than Intraday) - so a weekly close couldn't vary by hour say. If you want intraday timeseries you can request any intraday frequency eg hourly (we carry Tick, Minute & Hour) closes and then perhaps aggregate using a dataframe function. I wrote a sample in python demonstrating this using some of the re-sampling features in pandas to turn an hourly timeseries into a fourhour tiemseries. You can see that here. I'm certain R has similar.

    I don't think we would change the generic format of the Timestamp as it needs to serve generically (including say Tick use cases which require that time resolution) - but you should easily be able to write a function which truncates that for you eg get intraday prices which includes the time portion or get interday prices which does not. Or perhaps put in a request at the github site for the R wrapper.

    I hope this can help.

    Thanks @jason.ramchandani. The truncation is easy, was just looking for convenience as this data is not needed for interday retrievals, no big issue. For interday data (daily,weekly..) all the fields retrieved are identical with no regard to the timestamp. I did see in your python example that you're able to get away just with the date.

    My query is that there seems to be a problem with both the intraday and interday timestamp implementation. For interday I ran a daily query in 2 modes which gave me an additional entry I don't understand:

    For intraday, for hourly and ticker data I get dates outside of the start-end date interval (the full result is a few thousand lines):

    Hi @claudiu also the following response seems to work correctly:

    df = get_timeseries('IBM','*',start_date = '2017-03-21T00:00:00Z',end_date='2017-03-21T16:00:00Z',interval='hour')

    > print(df)

    3 2017-03-21T16:00:00Z 174.73 173.85 174.675 174.595 3427 595486 IBM

    I expected this response as the US market opens in the GMT early afternoon - so the hours between 00:00:00 and 14:00:00 will not be populated
