My portfolio and watchlist are displayed and then I get this.

What could this be?

I am assuming the implementation of Bollinger Moving Averages is missing from the code provided. You can either write your own definition to implement it or wait for the authors to provide the code for it.

Here is a repo i found that might help you understand what Bollinger moving/rolling averages are -
Umesh's Repo

UPDATE:

In case you are still looking for the answer, here is what i did -

your code is unable to detect the bollinger_mavg method from the 'ta' library.

I changed the code to fix this issue -

import ta as ta

and then replace

bollinger_mavg(.......)
with
ta.volatility.bollinger_mavg(.....)

Here is the link.
