we'll definitely need some code you're using (what the parameters are you call that function with).
Also - what's the result if you run backtesting on the same strategy/code?
I'm investigating further. I've found that the pair where the error happens is LUNA/USDT on Binance. I wonder if the huge crash is causing this. I'm not why this happens only on with --analyze-per-epoch
enabled though.
Backtesting and normal hyperopt works fine
I'm not sure why but the error doesn't happen if you call qtpylib
before pandas_ta.cti
- do you have any ideas? You can also write it like this and it fixes it:
def populate_indicators(self, dataframe: DataFrame, metadata: dict) -> DataFrame:
qtpylib
pandas_ta.cti(dataframe.close, 100)
well not having seen your original call - no?
you can literally use the SampleStrategy file below. If you comment out import freqtrade.vendor.qtpylib.indicators as qtpylib
, you will get the warning on LUNA 4h.

well indicators disables some warnings (warnings.simplefilter(action="ignore", category=RuntimeWarning)
) ...
so the most likely reason is that the warnings are always there - just hyperopt is not disabling these warnings in some areas.
yep, that's what I was worried about...
I think your best bet for this will be to report this to pandas_ta - maybe they have some suggestions or reasons as to why this happens.
You'll probably have to strip it from freqtrade code - but we do provide methods to load the data directly (maybe into a notebook) - so this can be tested and shown detached from freqtrade code.
Any news on this? knowing you a bit i'm sure you've investigated this further - so i'm curious as to what the outcome was.
i do think that the warning is always there (independent of hyperopt / the hyperopt mode) - but qtpylib is hiding it in most instances (not in hyperopt - but that's easily possible due to the way hyperopt works).
I haven't asked them but, from a quick check, it happens on LUNA-USDT-4h when the length is set to 1 and it happens only the first time I run it (I guess the warning gets disabled if I try again).
The point is that I wasn't using length=1 as a parameter in my strategy so it's either something that gets used under the hood (maybe for some checks?) or there's something else happening when using analyze-per-epoch
the error comes from linreg - which is used by several other indicators.
wasn't luna suspended for a time? maybe it's the missing candles (near or at 0) that cause problems?
Unfortunately, this is not something we will be able to fix here.
Errors are surpressed when importing qtpylib.indicators - but the error itself is coming from pandas_ta - so this is best investigated with them.
