当前,我正在尝试从IB API请求数据,但是存在一个小的格式化问题。
API给我以下输出:
AAPL; 20190507 16:20:00; price; price; price; price; number
我希望数据返回为:
AAPL; 20190507; 16:20:00; price; price; price; price; number
我正在使用以下代码
from ibapi.client import EClient
from ibapi.wrapper import EWrapper
from ibapi.contract import Contract
class TestApp(EWrapper, EClient):
def __init__(self):
EClient.__init__(self, self)
def error(self, reqId, errorCode, errorString):
print("error: ", reqId, " ", errorCode, " ", errorString)
def historicalData(self, reqId, bar):
print("AAPL", ";", bar.date, ";", bar.open, ";", bar.high, ";", bar.low, ";", bar.close, ";", bar.volume)
def main():
app = TestApp()
app.connect("127.0.0.1", 7497, 0)
contract = Contract ()
contract.symbol = "AAPL"
contract.secType = "STK"
contract.exchange = "SMART"
contract.currency = "USD"
contract.primaryExchange = "NASDAQ"
app.reqHistoricalData(0, contract, "", "1 D", "1 min", "TRADES", 0, 1, False, [])
app.run()
if __name__ == "__main__":
main()
bar.date在这种情况下为我提供了日期和时间
print("AAPL", ";", bar.date, ";", bar.open, ";", bar.high, ";", bar.low, ";", bar.close, ";", bar.volume)
有人可以帮我吗?

尝试一下:
'; '.join(bar.date.split(' '))
或者:
bar.date.replace(' ', '; ')
这两种方法都将用分号和空格替换日期/时间输出中的空格。

据我了解,bar.date
包含"20190507 16:20:00"
。
因此,您可以在提供的最后bar.date
中将"; ".join(bar.date.split(" "))
替换为print()
。
