Found an error in the ols.py indicator library - class OLS_BetaN uses pandas.ols which is I think depreciated (anyway doesn't work). You should update it to scipy's linregress or similar.
Also the Community gateway is down (error 502). I am a novice user and am trying to find information there on creating a slope from a self.line e.g. (closing prices over time (such as 10 days)). I can regress two existing indicators (e.g., closing prices vs opening prices) but cannot create an indicator that regresses over a linear array as it hangs and I have to keyboard interrupt, getting part of the following traceback:

File "C:\Users\Trader\AppData\Local\Programs\Python\Python311\Lib\site-packages\backtrader\strategy.py", line 394, in _start
self._periodset()
File "C:\Users\Trader\AppData\Local\Programs\Python\Python311\Lib\site-packages\backtrader\strategy.py", line 175, in _periodset
clk2 = getattr(clk._owner, '_clock', None)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You have written a very interesting and useful set of code but if you could add these small corrections/enhancements, I would appreciate it.
