-    Crucial part in this test is the "since" calculation.
-    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.
