Describe the problem:
KuCoin appears to be missing all trade data.
It appears this is an issue on KuCoin’s end, but I’m surprised I haven’t seen any reports on this. I am able to query fulfilled orders from earlier this year (2022) when querying their API directly, but I am unable to query my history from last year at all. And yes - I am aware that the API limits to querying a week’s window at a time. I adjusted accordingly.
Here is an example that works for me when providing start/end unix timestamps from this year where I made trades
import API from 'kucoin-node-sdk';
import config from './.config.js';
API.init(config);
const prettyFormatJSON = (data) => JSON.stringify(data, null, 2);
const res = await API.rest.Trade.Fills.getFillsList('TRADE', {
startAt: 1642377600000,
endAt: 1642636800000
})
console.log(prettyFormatJSON(res));
Not sure if the data would have been available via the V1 API, but that’s been turned off 
Which exchange/wallet is this regarding?
KuCoin
How did you import data into this wallet?
API Sync (I confirmed the key has proper read access), but I also tried to get a CSV download which also does not appear o work
What have you tried to fix this so far?
This whole problem started when I deleted and resynced my wallet because it was missing some trade information. Now it’s missing all internal KuCoin trade information. Again I assume it’s an issue on their end, but if not please advise and let me know if there’s anything I can do to help. If it is an issue on their end please apply some pressure on them to get this fixed if you have any levers to do so. The tax deadline for the US is rapidly approaching.
