我正在尝试创建一个LONG TRADE，其中将包含一个BUY ORDER和一个STOP-LOSS，使用Python asyncio，ccxt API（称为{{1 }}用于币安加密货币交易所。
首先，我创建购买订单。然后，我等到订单完成。 交易完成后，我试图创建一个止损定单来处理所创建的长线（原因：如果交易不利于我，我不想损失很多钱）
根据日志，确定正在创建“购买订单”。 我在STOP-LIMIT订单上收到“资金不足”。
我不明白为什么买入订单 顺利通过时，为什么我会在止损订单上获得“资金不足”的信息（甚至处于状态（已填充）。
如果我以9000美元的价格买进.0015 BTC（且订单已完成 Filled ），那么我应该能够以8875美元的价格止损.0015 BTC（同样，在这种情况下，您可以保留资金）贸易对我不利）
为什么这不起作用？为什么我不能为自己的交易创建止损？
TAKE_PROFIT 与 STOP_LOSS 相反。一个执行 向下执行，另一个执行向上执行。
问题：如何构造API，以便可以为订单设置 TAKE_PROFIT 和 STOP_LOSS ？
