Different return for fetch_historical_prices_by_epic_and_date_range()

[breitdom]

Hi all!

Why is it that when I run the function 'fetch_historical_prices_by_epic_and_date_range()' I sometimes get a return that looks like this:

MultiIndex([( 'bid', 'Open'),
( 'bid', 'High'),
( 'bid', 'Low'),
( 'bid', 'Close'),
( 'ask', 'Open'),
( 'ask', 'High'),
( 'ask', 'Low'),
( 'ask', 'Close'),
('last', 'Open'),
('last', 'High'),
('last', 'Low'),
('last', 'Close'),
('last', 'Volume')],
)

And sometimes like this:

MultiIndex([('bid', 'Open'),
('bid', 'High'),
('bid', 'Low'),
('bid', 'Close'),
('ask', 'Open'),
('ask', 'High'),
('ask', 'Low'),
('ask', 'Close')],
)

I always call this function the same way in my code. It seems to be a random principle. What could be the reason for this?

This example doesn't provide Volume. I have tried version=1 and version=2.
epic = 'IX.D.DAX.IFMM.IP' resolution = '30MIN' current_date_str = '2024-02-23T22:30:00' next_date_str = '2024-02-26T17:30:00' response = ig_service.fetch_historical_prices_by_epic_and_date_range(epic=epic, resolution=resolution, start_date=current_date_str, end_date=next_date_str, version='1')

But when i try the same request with https://labs.ig.com/sample-apps/api-companion/index.html, the response is correct.

Many thanks for any help :-)

Best regards
Dominik
