无法使用 Binance Python API 设置止损限价单

Question

我正在尝试使用Python asyncio、ccxt API（为 Binance Crypto Exchange 调用Binance API）创建一个包含BUY ORDER 和STOP-LOSS 的LONG TRADE。

首先我创建了购买订单。之后，我等到订单完成。 成交后，我正在尝试创建一个与创建的 LONG 一致的止损订单（原因：如果交易对我不利，我不想损失很多钱） .

根据日志，BUY ORDER 正在创建中。 我在 STOP-LIMIT 订单上收到“资金不足”。

我不明白为什么当买入订单 顺利通过时，我会在止损订单上获得“资金不足”（它甚至有状态已填充）。

如果我以 9000 美元的价格买入 .0015 BTC（并且订单已FILLED），我应该能够以 8875 美元的价格止损 .0015 BTC（再次，以保留案件中的资金交易对我不利）

为什么这不起作用？为什么我不能为我的交易创建止损？

ETA：在另一个线程中看到了这个：

TAKE_PROFIT 与 STOP_LOSS 相反。一个在 向下，另一个向上执行。

问题：如何构建 API 以便为订单设置 TAKE_PROFIT 和 STOP_LOSS？

async def execute_long_trade(self, trade: LongTrade):
    try:
        buy_price = trade.start_price
        sell_price = trade.exit_price
        symbol = trade.exchange_symbol
        amount = trade.amount
        stop_loss = trade.stop_loss

        order = self.exchange.ccxt_create_buy_order(symbol, amount, buy_price, 0 )

[...剪辑...]

        logging.info(f'Opened long trade: {amount} of {symbol}. Target buy {stop_loss}, sell price {sell_price}')

        await self._wait_order_complete(order["data"][0]["id"], symbol)

        # set up a stop loss order
        order = self.exchange.ccxt_create_sell_order(symbol, amount, sell_price, stop_loss )

        logging.info(f'Completed long trade: {amount} of {symbol}. Bought at {buy_price} and sold at {sell_price}')

    except ExchangeError as e:
        raise

    except Exception as e:
        print (" unexpected exception ")
        exit()

CALLING BINANCE（用于购买部分 - 效果很好）：

    def ccxt_create_buy_order( self, symbol: str, amount: float, price: float, stop_price: float ):
        try:
            results = {}

            if ( stop_price > 0 ):
                params = { 'stopPrice': stop_price - 10 }
                output  = self.ccxt_binance.createOrder(symbol, 'STOP_LOSS_LIMIT', amount=amount, side="buy",
                        price = stop_price, params=params)
            else:
                output  = self.ccxt_binance.create_order(symbol=symbol, type="limit", side="buy",\
                    amount=amount, price=price )

[ ... snip ...]
            return (results)

        except ccxt.InsufficientFunds as e:
            print ("insufficient funds)
            return

        except Exception as e:
            print (" unexpected error ")
            exit()

CALLING BINANCE（对于 SELL 部分 - 出现“资金不足”错误）：

    def ccxt_create_sell_order( self, symbol: str, amount: float, price: float, stop_price: float  ):
        try:
            results = {}

            if ( stop_price > 0 ):
                params = { 'stopPrice': stop_price + 10 }
                output  = self.ccxt_binance.createOrder(symbol, 'STOP_LOSS_LIMIT', amount=amount, \
                        side="sell", price = stop_price, params=params)
                print(output)
            else:
                output  = self.ccxt_binance.create_order(symbol=symbol, \
                    type="limit", side="sell",amount=amount )

[ ... snip ...]

            return (results)

        except ccxt.InsufficientFunds as e:
            print ("insufficient funds)
            return

        except Exception as e:
            print (" unexpected error ")
            exit()

Answer 1

您的限价单 api post 中没有价格

Answer 2

def ccxt_create_sell_order（自我，符号：str，金额：浮动，价格：浮动，stop_price：浮动）： 尝试： 结果 = {}

        if ( stop_price > 0 ):
            params = { 'stopPrice': stop_price + 10 }
