python-binance order_limit_buy() APIError(code=-1013):过滤器失败:LOT_SIZE

如何解决python-binance order_limit_buy() APIError(code=-1013):过滤器失败:LOT_SIZE

我在使用 python-binance 执行限价买单时遇到问题。限价卖单功能执行得很好。我的账户中有 35.95302628 USDT 的余额。 0.06545172930180404 * 548.26772 USDT = 35.89 USDT

self.client = Client(KEY,Secret)

def round_decimals_down(self,number:float,decimals:int=2):
    """
    Returns a value rounded down to a specific number of decimal places.
    """
    self.number = number
    self.decimals = decimals
    if not isinstance(self.decimals,int):
        raise TypeError("decimal places must be an integer")
    elif self.decimals < 0:
        raise ValueError("decimal places has to be 0 or more")
    elif self.decimals == 0:
        return math.floor(self.number)

    factor = 10 ** self.decimals
    return math.floor(self.number * factor) / factor


def sell(self,symbol,offerSellPrice):
    self.symbol = symbol
    self.sellSymbol = (self.symbol + str("USDT"))
    self.quantity = self.cursor.execute("SELECT " + self.symbol + "Quantity FROM Table WHERE tID = (SELECT MAX(tID) FROM Table)").fetchval()
    self.offerSellPrice = offerSellPrice

    self.order = self.client.order_limit_sell(symbol=self.sellSymbol,quantity=self.round_decimals_down(self.quantity,6),price=self.round_decimals_down(self.offerSellPrice,2))


def buy(self,cryptoQuantity,offerBuyPrice):
    self.buySymbol = (symbol + str("USDT"))
    self.cryptoQuantity = cryptoQuantity
    self.offerBuyPrice = offerBuyPrice
    
    self.order = self.client.order_limit_buy(symbol=self.buySymbol,quantity=self.round_decimals_down(self.cryptoQuantity,price=self.round_decimals_down(self.offerBuyPrice,2))

buy('BCH',0.06545172930180404,548.26772)

print(info)

返回:

LOT_SIZE

{'filterType': 'LOT_SIZE','stepSize': '0.00001000'}

我的订单数量大于'minQt': '0.00001000'

我也以 8 的精度(数量)进行了尝试,但收到了相同的错误。

如有任何建议,我们将不胜感激。
