Is this the last PR? if so add the changelog entry

Querying the trades with the API key that we have I got:

Error response from HTX. URL: https://api.huobi.pro/v1/order/matchresults, Response: {"status":"error","err-code":"invalid-start-time","err-msg":"invalid.start.time (NT)","data":null}

Still things not addressed from last PR review...

LGTM as what I asked is there.

One TODO that comes out of it is what I wrote in discord:

But you can do better and also check that the request to the CEX matches what you
expect. So test the request part too. Cause right now the app can send a ping to the > CEX and the test would happily pass.
Please fix this in another PR. If this is green.
