Now that you know a little about me, let me tell you about the issue I am
having:

Catalyst fails when running an algo (starting with the buy_and_hodl.py suggested in the tutorial).

• What did you expect to happen?

Trading algorithm should have run with no errors.

• What happened instead?

Catalyst throws the following error:

$ catalyst run -f buy_and_hodl.py --start 2015-3-1 --end 2017-6-28 --capital-base 100000 -o bah.pickle

Here is how you can reproduce this issue on your machine:

Reproduction Steps

First time you run: catalyst run -f buy_and_hodl.py --start 2015-3-1 --end 2017-6-28 --capital-base 100000 -o bah.pickle

What steps have you taken to resolve this already?

If you run the same command a second time, the error disappears.

Anything else?

No

Sincerely,
Victor

This may be fixed by #20
