Sorry I may ask a stupid question but I am just a beginner in python and algotrading. I am now using Python 3.7 and ibapi with ib_insync to try connect TWS. However, as Python 3.7 use async as a keyword so when I try to code with ib_insync:
from ib_insync import *
ib = IB()
ib.connect('127.0.0.1', 7496, clientId=1)
contract = Forex('EURUSD')
bars = ib.reqHistoricalData(contract, endDateTime='', durationStr='30 D', barSizeSetting='1 hour', whatToShow='MIDPOINT', useRTH=True)
df = util.df(bars)
print(df['date', 'open', 'high', 'low', 'close'])
It end up like this:
File "C:/Users/leung/Documents/MONEY/Algotrade/venv/test1.py", line 1, in <module>
from ib_insync import *

self.async = False

SyntaxError: invalid syntax

I know I need to change the name async to other name. I tried to modify the file client.py in ibapi but it seems not work at all. Which part of code I should change in order to get it work?
Install newest version (API_Version=9.75.01) of IB API SW - this issue is fixed there. It is Python 3.7 dependent - same code worked well running Python 3.6 for me.
