binance.exceptions.BinanceAPIException: APIError(代码=-1013)：过滤失败: LOT_SIZE

Question

我想卖XRP/USDT。这是假设我有超过最低限度，甚至49个XRP是超过15usd。

最低: 0.10000000 XRP = 49.95301600

sym = 'XRP'
bol = 'USDT'
symbol = sym+bol

from binance.client import Client
client = Client(api_key, api_secret)

# Minimum
minimum = client.get_symbol_info(symbol)
print(minimum['filters'][2]['minQty'])

quantity = client.get_asset_balance(asset=sym)['free']
print(quantity)

order = client.create_order(
    symbol=symbol,
    side=Client.SIDE_SELL,
    type=Client.ORDER_TYPE_MARKET,
    quantity=quantity)

我得到了：

 File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/binance/client.py", line 1200, in create_order
    return self._post('order', True, data=params)

    raise BinanceAPIException(self.response)
binance.exceptions.BinanceAPIException: APIError(code=-1013): Filter failure: LOT_SIZE

我做错了什么？

Answer 1

根据the Binance trade rules和你最初的帖子，XRP/USDT的最低要求是0.1，这意味着你不能交易少于0.1的XRP数量。

您应该尝试将数量截断到小数点后一位。

Answer 2

首先，您需要调用GET /api/v3/exchangeInfo。在那里，您可以找到每个Binance对的过滤器信息。XRPUSDT有几个筛选器。关于LOT_SIZE的那个

    {
      filterType: 'LOT_SIZE',
      minQty: '0.10000000',
      maxQty: '9000000.00000000',
      stepSize: '0.10000000'
    },

所以你的量步必须在0.1以内。
