Description

I am getting {"msg":"Order side invalid.","code":"400100"} errors on kucoin. They started yesterday. I could not find this error code in the documentation. How can I fix it? Is there a problem in ccxt?

The failing code is : exchange.createLimitOrder(symbol, trade_type, trade_amount, limit_price)

The output of verbose for the failing code is as follows:

@duncanmcl It works for me. Have you checked your balance?

kucoin.createLimitOrder (ENA/USDT, SELL, 1, 1.5)

I found the reason. It looks like SELL command became case sensitive in Kucoin (at least for me).

This python code is giving error {"msg":"Order side invalid.","code":"400100"}:

response = exchange.createLimitOrder("ENA/USDT", "SELL",1,1.5)

Verbose output of the uppercase "SELL" code is:

RequestBody: {"clientOid":"2624adef-cbde-4caa-9bbc-27a30496cf58","side":"SELL","symbol":"ENA-USDT","type":"limit","size":"1","price":"1.5"}

However, this code is working:

response = exchange.createLimitOrder("ENA/USDT", "sell",1,1.5)

Verbose output of the lower case "sell" code is

RequestBody: {"clientOid":"7ee965cd-803c-4e4f-a2eb-6fb8b98a853a","side":"sell","symbol":"ENA-USDT","type":"limit","size":"1","price":"1.5"}

Uppercase SELL command was also working until this Sunday on Kucoin. I did not change anthing in the code, but the command stopped working on Sunday. Maybe, the api server that serves my account has been updated with new software.

It's worked and solve my problem in node.js too, thanks

@duncanmcl It looks like the side should be either sell or buy according to their documentation (https://www.kucoin.com/docs/rest/spot-trading/orders/place-order).

Now it works for both uppercase and lowercase.
