period="max" fails with multiple intervals

[cole-st-john]

Describe bug

Should:

Intuitively, when downloading price history, i am expecting using period="max" should return all available data for any interval.

Is:

Mode1 - Bug (what I want to focus on here): Currently, yfinance fails on a number of intervals - returning an empty dataframe.
Mode2 - Feature: I would expect for 1m, requests would be chunked so that the entirety of the available (30 day period) data would be requested in chunks and unioned into a single result.

Simple code that reproduces your problem

import yfinance as yf

INTRADAY_INTERVALS = ["1m", "2m", "5m", "15m", "30m", "60m", "1h", "90m"]
DAY_PLUS_INTERVALS = ["1d", "5d", "1wk", "1mo", "3mo"]
INTERVALS = [*INTRADAY_INTERVALS, *DAY_PLUS_INTERVALS]
TICKERS = ["EURUSD=X"]

for interval in INTERVALS:
    df = yf.download(tickers=TICKERS, period="max", interval=interval, progress=False)
    print(f"failed for {interval}") if df.empty else print(f"passed for {interval}")

yfinance version

Python version

3.12.10

Operating system

wsl - ubuntu

Next Steps:

I would be happy to debug and create a PR - I do see that there have been some issues / features identified in the past with period="max" being one of the arguments, but none purely focusing on the root cause issues around the implemented logic around period "max".

Thanks,
Cole

Hello, just checking in to see if there are any thoughts on this issue - as it continues in 0.2.61. Happy to provide more details if needed! I'm also happy to share a draft fix if addressing this aligns with the project's needs!

[ValueRaider]

i am expecting using period="max" should return all available data for any interval.

Reframe as: yfinance should ask Yahoo for all available data. yfinance role is sending valid request.

Have to be careful about having 1 yfinance function call trigger multiple web requests - rate limit.

Also I can't reproduce any of those errors - I tested intervals 1d down to 1m.

[cole-st-john]

I dont disagree with you on framing of Mode 2. Again, as I wrote above, in this issue I actually wanted to focus on failure mode 1 (failure for different intervals).

Interesting that you couldn't reproduce. Would you be open to testing in a docker container (given that the current github pytest action is not in running order)?

If so, please consider using this:
https://github.com/cole-st-john/yfinance/tree/automate_max_test/docker - the instructions to run are inside the Dockerfile.

[ValueRaider]

Not tried your Docker.

I had a closer look at yfinance code. "max" is never sent to Yahoo, instead it's converted to start and end dates. Except for interval 2m, yfinance skips that (bug). So I only get error on 2m.

What happens if you skip over 2m, or fix bug in history.py? I wonder if that is triggering errors for subsequent fetches.

[cole-st-john]

@ValueRaider :

You are correct about the bug with 2m not being included correctly in the conditional logic - it leads to a consistent issue with 2m.

I did some further testing and your second hypothesis didnt hold up, however. The other intraday intervals all have inconsistent issues when tested in a container.

I tried to describe/address in PR #2508 .
