"Order size increment invalid" when using decimals.

mkmnstr123 commented 3 years ago

Hello,

So, I've been working for a while using the SDK and I noted that there is a problem when trying to use decimals. Also I noted this happens also in other of your libraries. Here is an example:

https://github.com/ccxt/ccxt/issues/1846#issuecomment-364370011

Also, in that thread it mentions a catalogue of valid decimal points, can you please provide it?

Thanks

Request:

   "size":"3258.921114",
   "symbol":"ADA-USDT",
   "type":"MARKET",
   "side":"sell",
   "timeInForce":"IOC"
}

Response: {"code":"400100","msg":"Order size increment invalid."}

did you try restricting your size amount to three or four places to see if that works?

Please refer to our documentation: https://www.kucoin.com/docs/rest/spot-trading/orders/place-order

Size (Size) When placing a limit order, size refers to the amount of trading targets (the asset name written in front) for the trading pair. Teh Size must be based on the baseIncrement of the trading pair. The baseIncrement represents the precision for the trading pair. The size of an order must be a positive-integer multiple of baseIncrement and must be between baseMinSize and baseMaxSize.

Funds (Funds) When placing a market order, the funds field refers to the funds for the priced asset (the asset name written latter) of the trading pair. The funds must be based on the quoteIncrement of the trading pair. The quoteIncrement represents the precision of the trading pair. The funds value for an order must be a multiple of quoteIncrement and must be between quoteMinSize and quoteMaxSize.

So use the following code to retrieve the information you need

$symbol->getListV2('BTC');

Please modify your code to try again. If you encounter any issues, feel free to provide feedback.
