Binance Api [buy limit] it says that I have no funds to make the purchase but in fact there are

Question

Hi everyone I'm trying to use Binace's bees and so far everything has been fine, I have already made some purchases and sells using the market order mode, all perfect, now I'm trying to place a Limit order.

but I always get the same answer.

"{"code":-2010,"msg":"Account has insufficient balance for requested action."}"

My wallet consists of two test cryptocurrencies:

BNB -> free 0.07100 | Locked 0

USDT -> free 50.69828637 | Locked 0

I'm trying to make the request like this:

symbol=BNBUSDT&type=LIMIT&timeInForce=GTC&quantity=0.333&price=120.001&side=BUY&recvWindow=5000&timestamp=1616195182000

This is my main code and as you can see i set the parameters correctly, what can it be?

$request = [
   BinanceEndpointApi::fieldSymbol => 'BNBUSDT',
   BinanceEndpointApi::fieldType => 'LIMIT',
   BinanceEndpointApi::fieldTimeInForce => 'GTC',
   BinanceEndpointApi::fieldQuantity => number_format( (30/120),3),
   BinanceEndpointApi::fieldPrice => 120.001,
   BinanceEndpointApi::fieldSide => 'BUY'
];

$res = $binance->openClosePosition(BinanceEndpointApi::order, $request);
\Kint::dump($res);

here is the screen shown by kint

This is two method used in a class binace to make request

    /**
     * @param string $signature
     * @return string
     */
    private function getSignature(string $signature)
    {
        return hash_hmac('sha256', $signature, $this->secretKey);
    }
    /**
     * @param string $urlApi
     * @param array $request
     * @return array|null
     */
    public function openClosePosition(string $urlApi,array $request) {
        $request['timestamp'] = time() * 1000;
        $buildQuery = http_build_query($request);
        $signature = $this->getSignature($buildQuery);

        if(!empty($buildQuery)) {
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $urlApi);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
            curl_setopt($ch, CURLOPT_HEADER, FALSE);
            curl_setopt($ch, CURLOPT_POST, TRUE);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $buildQuery . "&signature=" . $signature);
            curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded", "X-MBX-APIKEY: " . $this->apiKey));
            $response = curl_exec($ch);
            curl_close($ch);

            return [
                'request' => $buildQuery,
                'response' => $response
            ];
        }else {
            return NULL;
        }
    }

What am I doing wrong?

Answer 1

I solved the problem, I made the same call made yesterday without changing anything, it seems that binance had not immediately updated the status of my wallet.
