【问题描述】:
我是 Python 和 ibapi 的新手,我问过盈透证券本身,他们只告诉我:
self.done 最初是在父类 EClient 中定义的 用于表示当前 API 连接“完成”。你应该 不要将其用作停止您自己构建的循环的指标。 在完成之前,您可以保持一个 API 客户端连接处于活动状态 下载了您需要的所有历史数据。如果你需要减速 请求数据的速度,可以使用其他线程控制 python,例如 sleep() 函数,在您的 循环,因此它不会发送所有合约的历史数据请求 一次。
所以我认为错误来自
self.done = True
这是我的代码
from ibapi import wrapper
from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract as IBcontract
from threading import Thread
import queue
import datetime
from ibapi.utils import iswrapper #just for decorator
from ibapi.common import *
from ibapi.contract import *
from ibapi.ticktype import *
class TestApp(wrapper.EWrapper, EClient):
def __init__(self):
wrapper.EWrapper.__init__(self)
EClient.__init__(self, wrapper=self)
@iswrapper
def historicalData(self, reqId:int, bar: BarData):
print("HistoricalData. ", reqId, " Date:", bar.date, "Open:", bar.open,
"High:", bar.high, "Low:", bar.low, "Close:", bar.close, "Volume:", bar.volume,
"Count:", bar.barCount, "WAP:", bar.average)
if all_data.iloc[reqId,7] == 0:
all_data.iloc[reqId,7] = bar.close
self.done = True
@iswrapper
def historicalDataEnd(self, reqId: int, start: str, end: str):
super().historicalDataEnd(reqId, start, end)
print("HistoricalDataEnd ", reqId, "from", start, "to", end)
@iswrapper
def historicalDataUpdate(self, reqId: int, bar: BarData):
print("HistoricalDataUpdate. ", reqId, " Date:", bar.date, "Open:", bar.open,
"High:", bar.high, "Low:", bar.low, "Close:", bar.close, "Volume:", bar.volume,
"Count:", bar.barCount, "WAP:", bar.average)
def main():
t = time()
max_amount_per_Iter = 70 #max number per iter to save cost
max_Iter = ceil(len(all_data)/max_amount_per_Iter)
for i in range (0,max_Iter):
print('====================round : ',i+1,'===============================')
app = TestApp()
app.connect("127.0.0.1", 7496, clientId=i)
print("serverVersion:%s connectionTime:%s" % (app.serverVersion(),app.twsConnectionTime()))
for j in range (0,min(max_amount_per_Iter,len(all_data)-i*max_amount_per_Iter)):
print(j+i*70)
app.i = j+i*max_amount_per_Iter
contract = Contract()
contract.symbol = all_data.iloc[app.i,0]
contract.secType = all_data.iloc[app.i,1]
contract.currency = all_data.iloc[app.i,3]
contract.exchange = all_data.iloc[app.i,2]
app.reqHistoricalData(app.i, contract, "","1 W", "1 day", "Adjusted_Last", 1, 1, False, [])
app.run()
sleep(1)
app.disconnect()
sleep(0.02)
print('=========End round : ',i+1,'with time :',time() - t,'==============')
if __name__ == "__main__":
main()
我希望看到一个建议,如何在不使用 self.done 或断开我的 TWS 的情况下传递到下一个迭代。如果我不包括 self.done 程序将在第一次 i=0,j=0 迭代时无限循环运行,没有人告诉它退出。
所以如果你不知道可以解决我的直接答案,你可以建议:
在这种情况下还有其他可以使用的流量控制吗?
或者cancelHistoricalData命令,如果它可以用于这种情况?
或者有什么方法可以在 Class 中构建 Class 并只在子类中执行 self.done = True 而不会断开我在 Class 中的 ID?
PS。我对 requestMarketData 有同样的问题
更新 V2 这是我尝试打印的一些结果

【问题讨论】:
-
你能告诉我到底是什么问题吗?我看到你想下载历史数据,但你没有告诉你出了什么问题。你没拿到数据吗?还是出错了?您也可以分享您发送给 IB 的问题。我无法从答案中弄清楚。
-
我已经添加了结果。谢谢你的建议!
-
您是否正确缩进了这个示例代码?
-
我认为 self.done=true 会断开客户端的连接。如果您只是注释掉该行,您的输出是什么?我预计起搏违规错误。
-
是的,Janos 我只是评论那行,抱歉我的英语不好。
