Q: How can set the type of starting an order? (LONG or SHORT)

[BaseMax]

<?php
// ....
$order = [
    'clientOid' => uniqid(),
    'price'     => '1',
    'size'      => '1',
    'symbol'    => 'BTC-USDT',
    'type'      => 'limit',
    'side'      => 'sell',
    'remark'    => 'ORDER#' . time(),
];
try {
    $result = $api->create($order);
    var_dump($result);
} catch (\Throwable $e) {
    var_dump($e->getMessage());
}

Here, I am trying to start order with the SELL type.

Does everything correct and my code should work? or do I miss understanding something?

Does this only work in FEATURES mode? not normal mode?

Any kind of help is welcome. Thanks in advance.

You are using the Spot SDK now, I think the parameters are ok. Any questions ? Could you please give me the whole error that KuCoin sent to you?

It seems it's not possible to open order with a SELL position.

Q: Opening order with a SELL position only allowed in features MODE?

My problem is fixed, Opening an order with the Sell position is only allowed in Features mode. I switched to features and the error was solved.

Thanks.
