SyntaxError: invalid syntax

You have a syntax error, but it look like you haven't posted your whole code. Typo in `qiantity` in the `make_order` function as well — liamhawkins, Mar 09 '19 at 11:38
thanks didn't see the typo at all and this is all my code to see more about what I mean check out this youtube video I was referencing (alongside a book) -> https://www.youtube.com/watch?v=Bu0kpU-ozaw — Millz, Mar 09 '19 at 11:46

The syntax of the except clause has changed between Python 2 and Python 3.

Python 2:

except (socket.error, ), ex:

would be in Python 3:

except (socket.error, ) as ex:

It seems that your code was written for Python 2. Either run it with Python 2 or find an updated version of the code.

now working better giving me a display of "Server Version: 76 TWS Time at connection:20190309 12:09:08 Greenwich Mean Time" when I type main() after running the program however the program interative broker is not picking up the order or takes me a few times before it realises something ???: – Millz Mar 09 '19 at 12:11
This might be a different question, then. You can consider creating a new one with all the relevant information if you don't manage to solve it! – Thierry Lathuille Mar 09 '19 at 12:19
