如何從交互式經紀人API獲取歷史股價數據？

Question

我想使用IBAPI來獲取歷史庫存數據。 我的代碼不起作用，什么也沒有返回。 有人可以幫我編輯代碼嗎？ 謝謝

from ibapi import client
from ibapi import wrapper
import datetime
from ibapi.contract import Contract
from ibapi.common import BarData

# ! [socket_init]
class App(wrapper.EWrapper,client.EClient):
    def __init__(self):
        wrapper.EWrapper.__init__(self)
        client.EClient.__init__(self, wrapper=self)


 #Build a sample contract
contract = Contract();
contract.symbol = "9005.T";
contract.secType = "STK";
contract.currency = "JPY";
contract.exchange = "SMART";


app = App()
app.connect(host='localhost',port=7497, clientId=3)
print(app.isConnected())
queryTime = (datetime.datetime.today() - datetime.timedelta(days=180)).strftime("%Y%m%d %H:%M:%S")
print(app.reqHistoricalData(4102, contract, queryTime,"1 M", "1 day", "MIDPOINT", 1, 1, False, []))
queryTime = (datetime.datetime.today() - datetime.timedelta(days=180)).strftime("%Y%m%d %H:%M:%S")
print(app.historicalData(4102,BarData))


OUTPUT:
True
None
None

我試圖閱讀源代碼。 但是我發現對我來說很難理解。 其他帖子顯示的答案似乎與最新的api版本無關。

這就是我要做的。

class App(wrapper.EWrapper,client.EClient):類EClient如果我想重寫EClient任何方法，我只會將其作為子類。 我不是很用python，但是在其他語言中卻是如此。

在class App您需要覆蓋您感興趣的方法，例如historicalData

在app.connect之后，您必須調用app.run()以啟動它的消息閱讀器線程。 一旦該線程獲得控制權，它將阻塞您的程序，因此您必須異步執行程序流。

我將數字放在注釋中，以便您查看流程。

from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
from ibapi.common import BarData

import datetime

class MyWrapper(EWrapper):

    def nextValidId(self, orderId:int):
        #4 first message received is this one
        print("setting nextValidOrderId: %d", orderId)
        self.nextValidOrderId = orderId
        #5 start requests here
        self.start()

    def historicalData(self, reqId:int, bar: BarData):
        #7 data is received for every bar
        print("HistoricalData. ReqId:", reqId, "BarData.", bar)

    def historicalDataEnd(self, reqId: int, start: str, end: str):
        #8 data is finished
        print("HistoricalDataEnd. ReqId:", reqId, "from", start, "to", end)
        #9 this is the logical end of your program
        app.disconnect()
        print("finished")

    def error(self, reqId, errorCode, errorString):
        # these messages can come anytime.
        print("Error. Id: " , reqId, " Code: " , errorCode , " Msg: " , errorString)

    def start(self):
        queryTime = (datetime.datetime.today() - datetime.timedelta(days=180)).strftime("%Y%m%d %H:%M:%S")

        fx = Contract()
        fx.secType = "CASH" 
        fx.symbol = "USD"
        fx.currency = "JPY"
        fx.exchange = "IDEALPRO"

        #6 request data, using fx since I don't have Japanese data
        app.reqHistoricalData(4102, fx, queryTime,"1 M", "1 day", "MIDPOINT", 1, 1, False, [])

app = EClient(MyWrapper()) #1 create wrapper subclass and pass it to EClient
app.connect("127.0.0.1", 7497, clientId=123) #2 connect to TWS/IBG
app.run() #3 start message thread
