<p>@jbaczuk possible but that would be very inefficient.</p>

<p>but i just noticed something. im in utc+1 so my <code>datetime.datetime.now()</code> produces timestamps that are in the future when looking from utc. </p>

<p>I trying to do some testing on historical coinbase data. Because I can only get 300 datapoints per request. Im looping the request and change the start and end paramter to got backwards. </p>

<p>My requests now look like this:
<a href="https://api.pro.coinbase.com/products/BTC-EUR/candles?granularity=60&amp;start=2018-11-09T17:11:08Z&amp;end=2018-11-09T18:11:08Z" rel="nofollow noreferrer">https://api.pro.coinbase.com/products/BTC-EUR/candles?granularity=60&amp;start=2018-11-09T17:11:08Z&amp;end=2018-11-09T18:11:08Z</a></p>

<p>AFAIK they are ISO 8601 formatted and the time difference between start and end is correct. </p>

<p>However, im getting not 60 points but 350, so the end date is ignored and the start date also changes whenever I reload the link. </p>

<p>Can someone shine some light on how to correctly do the request for 1 hour of data?</p>

I trying to do some testing on historical coinbase data. Because I can only get 300 datapoints per request. Im looping the request and change the start and end paramter to got backwards.

My requests now look like this:
<https://api.pro.coinbase.com/products/BTC-EUR/candles?granularity=60&start=2018-11-09T17:11:08Z&end=2018-11-09T18:11:08Z>

AFAIK they are ISO 8601 formatted and the time difference between start and end is correct.

However, im getting not 60 points but 350, so the end date is ignored and the start date also changes whenever I reload the link.

Can someone shine some light on how to correctly do the request for 1 hour of data?

So it looks like you need to parse and remove the extra data if you don't need it.
