Description

Hi, there. I'm trying to open a spot SELL limit order on ByBit and I'm encountering that CCXT rounds up the variables before sending them to open the limit order. And when I look at markets for this crypto pair, it says that:

[precision][amount] => 0.01
[precision][price] => 0.0001

The changes happen in $orderRequest = \ccxt\bybit->create_order_request() of the method \ccxt\bybit->create_order(). Here $orderRequest already contains such an array:

$orderRequest: Array
(
    [symbol] => RUNEUSDT
    [side] => Sell
    [orderType] => Limit
    [price] => 10.309
    [category] => spot
    [qty] => 5
)

which is then sent via API to ByBit. I.e. price from 10.3089 became 10.309, and qty from 5.04 became 5. And on the page https://www.bybit.com/ru-RU/trade/spot/RUNE/USDT itself the price 10.3089 is set and the qty 5.04 is also set.

Code

$account = Account::getOneAsArrayById(2);

$exchange = new \ccxt\bybit([
	'apiKey'          => $account['api_key'],
	'secret'          => $account['api_secret'],
	'password'        => $account['api_password'],
	'enableRateLimit' => true,
]);

$exchange->load_time_difference();

$symbol = 'RUNEUSDT';
$amount = 5.04;
$price  = 10.3089;
$params = [
	'category' => 'spot',
];

$result = $exchange->create_limit_sell_order($symbol, $amount, $price, $params);

thanks for the report! i've reproduced this. seems the issue is specific to PHP part, not in other langs.
I'll push a fix soon and let you know

seems i was in wrong direction. the problem is because of symbol id's clash.
Please try to use unified symbols format: RUNE/USDT (the slash between) for spot symbols, and RUNE/USDT:USDT format for USDT swap symbols.

$symbol = 'RUNE/USDT';
$amount = 5.04;
$price  = 10.3089;
$result = $exchange->create_order($symbol, 'limit', 'sell', $amount, $price);

it would work correctly. let us know if you'd face any further issues
