Fetch Orders using the "fetch_my_trades" endpoint and filter them by order-id.

The "since" argument passed in is coming from the database and is in UTC,
|
||
|
|
as timezone-native datetime object.
|
||
|
|
From the python documentation:
|
||
|
|
> Naive datetime instances are assumed to represent local time
|
||
|
|
Therefore, calling "since.timestamp()" will get the UTC timestamp, after applying the
|
||
|
|
transformation from local timezone to UTC.
|
||
|
|
This works for timezones UTC+ since then the result will contain trades from a few hours
|
||
|
|
instead of from the last 5 seconds, however fails for UTC- timezones,
|
||
|
|
since we're then asking for trades with a "since" argument in the future.
