我正在使用 python ccxt 在 binance 上下卖单。
order = exchange.create_order(symbol, 'market', 'sell', amount)
我已经获取了所需的精度，并且得到了 5。
markets = exchange.load_markets()
amount_precision = market['precision']['amount']
于是，我将原本
0.00025350097946714683844156988870.00025但是当我创建具有此金额值的订单时，我收到错误：
binance amount of BTC/USDT:USDT must be greater than minimum amount precision of 3
虽然我将精度设置为5，这是所需的值。
精度在 binance api 中的真正含义是什么？是有效位数吗？我需要一些澄清。
您可以使用以下代码来计算数量
market_data = exchange.market(symbol) # load info for your symbol
precision = market_data['precision']['amount']
min_order_amount = market_data['limits']['amount']['min'] # useful to avoid to trigger low amount error
# Determine the number of decimal places from the precision value
precision_decimal_places = max(0, int(-math.log10(precision))) # if precision is a float
precision_decimal_places = len(precision) - 2 #if precision is str (-2 to remove 0.)
# Ensure the quantity is within the allowed precision and limits
quantity = max(min_order_amount, round_down(quantity, precision_decimal_places))
