Why I try to get 1 minute data by using get_history， but returned data is missing ?

@Baojiayi_2025

Thank you for reaching out to us.

I used the historical pricing in content layer with the following code.

response1 = historical_pricing.summaries.Definition(
    "LCOv1", 
    interval=Intervals.MINUTE,    
    start = '2025-04-23T00:00:00', 
    end = '2025-04-24T23:59:59',
    fields=['OPEN_PRC', 'TRDPRC_1', 'HIGH_1', 'LOW_1'],
    extended_params={"summaryTimestampLabel":"endPeriod"}
).get_data()
response1.data.df

I assumed that your timezone is UTC+8.

df = response1.data.df
df[(df.index.get_level_values(0) >= '2025-04-24 08:26:00') & (df.index.get_level_values(0) <= '2025-04-24 08:34:00')][::-1]['TRDPRC_1']

The example code is on GitHub.

I checked and found that it doesn't support the OPINT_1 data for Intervals.MINUTE.

You can remove the fields parameter to retrieve all available fields.

Please contact the Historical Pricing support team via MyAccount to confirm if this field is available on the historical database.
