[英]320 Error after IBApi.EClient.placeOrder() in Python & Interactive Brokers
[英]Python Interactive Brokers ibapi
我在使用修改后的IB示例代碼為每個庫存訂單使用和增加“ orderId”時遇到麻煩。 我有一個在類中生成nextValidId並將其打印到stdout的方法,但是我不確定如何訪問在main()程序主體中創建的已定義屬性(self.nextValidOrderId)。 我能夠實例化EWrapper和EClient類並下訂單(如果我手動輸入orderId)。 在示例代碼中,我將其硬編碼為126。我想我可以在main()程序主體中使用以下代碼。 “ orderId = app.nextValidOrderId”,但是它不起作用。
`__author__ = 'noone'
from Testbed.OrderSamples import OrderSamples
from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.common import *
from ibapi.contract import *
class OrderApp(EWrapper, EClient):
def __init__(self):
EClient.__init__(self,self)
def error(self,reqId:TickerId, errorCode:int, errorString:str):
print("Error:",reqId," ", errorCode, " ", errorString)
# This is the initial response after connection to TS from the API providing next available OrderID
@iswrapper
def nextValidId(self, orderId: int):
super().nextValidId(orderId)
print("setting nextValidOrderId: %d", orderId)
self.nextValidOrderId = orderId
def contractDetails(self, reqId:int, contractDetails:ContractDetails):
print("contractDetails: ", reqId, " ", contractDetails)
def main():
app=OrderApp()
app.connect("127.0.0.1",7497,0)
## Build the contract object to be passed to the order Method
stock_contract = Contract()
stock_contract.symbol = 'AAPL'
stock_contract.secType = 'STK'
stock_contract.exchange = 'SMART'
stock_contract.currency = 'USD'
stock_contract.primaryExchange = 'NASDAQ'
# reqID must be provided to the Order. This method gets the reqID from IB DB's
app.reqContractDetails(10, stock_contract)
try:
# Now place the order in Paper Money Account
app.placeOrder(126, stock_contract, OrderSamples.LimitOrder("BUY", 50, 12))
except:
raise
app.run()
if __name__ == "__main__":
main()`
您的方法在語法上不正確。 它應該具有以下縮進形式
@iswrapper
def nextValidId(self, orderId: int):
super().nextValidId(orderId)
print("setting nextValidOrderId: %d", orderId)
self.nextValidOrderId = orderId
另外,您不導入功能裝飾器iswrapper
from ibapi.utils import iswrapper
希望這可以幫助
