Is anyone else having a problem where if they copy code from the new backtest menu and then paste back in to the algorithm work space, they get random spaces right at the beginning of empty lines causing syntax errors?
It's really beginning to annoy me, especially on larger codes where I have to go through 20 - 30 lines of spaces causing syntax errors before I can even begin work on the algorithm.
I am on Chrome:
Version 67.0.3396.99 (Official Build) (64-bit)
Yes, I have gotten those as well. I have fallen back to using the copy utility from the /old version that works without any issues.
Sorry for the inconvenience! There was a known extra-indentation issue on Firefox, which we fixed, but I'm not able to reproduce that same issue on Chrome - I'm also on Version 67.0.3396.99 (Official Build) (64-bit), using OS X.
Are there any particular add-ons that you guys are using on Chrome? I can try to install them and see if the bug shows up then.

Abhijeet,
# New backtest bug
def initialize(context):
pass
def before_trading_start(context, data):
stocks = symbols('SPY', 'QQQ')
n = len( stocks)
record(n = n)
After copying this simple code from Activity -> Code and pasting in IDE
I got:
4 Error SyntaxError: invalid syntax Chrome Version 67.0.3396.99 (Official Build) (64-bit)
If you will fix the code and run it for 2 years you may get this:
2 of 2
Structural Constraints Met
5 of 7
Risk Constraints Met
0.00 %
Total Returns Is not this another BIG bug?
I've only got Adblock and Norton installed. I'm getting this bug as well.
@Vladimir That's the same bug we're talking about here.
@Abhi, I have sent you an email with a video capture attachment that illustrates the copy bug and includes details of my windows 10 and Google Chrome versions. Hope that helps.
