Kucoin trades and closed-orders are limited until 7 days after the "since"

• OS: Ubuntu 18.04
• Programming Language version: JavaScript
• CCXT version: 1.18.880
• Exchange: Kucoin
• Method: fetchMyTrades, fetchClosedOrders

When the since parameter is given to the fetchMyTrades or fetchClosedOrders methods, an URL parameter called startAt is used to get data from the Kucoin API. I noticed from the returned objects that the data is limited until 7 days after the startAt.

To reproduce:

• have a trade on any Kucoin market.
• call fetchMyTrades on that market, with since=[trade.createdAt - (7 * 24 * 60 * 60 * 1000)] (7 days before that trade). The trade will be in the response.
• call fetchMyTrades again, with since=[trade.createdAt - (7 * 24 * 60 * 60 * 1000) - 1000] (7 days plus 1 second before that trade). The trade is now missing.

Suggestion for solution:

Maybe the easiest solution is to always send the endAt parameter with the current datetime, whenever the startAt is used.

actually nvm i found a solution for the trades, using /api/v1/limit/fills not sure about the orders however.

unfortunately the solution you suggested doesn’t work.

 {"code":"400100","msg":"The duration between the start time and the end time should not exceed 7 days."} 

and for fetchMyTrades if the time difference is longer than a week you get

 {"code":"400100","msg":"validation.queryOrder.timeRangeInvalid"} 

so i’m not sure how to solve this. Any help would be appreciated.
