Latest Version of fast_csv Broken the scan

[cotton1234]

Hello Benny,

I upgraded the fast_csv to version 2 and the stock patter is broken.
I have reverted to old version, once you get time, pls do check.

Thanks

It was part of update i was making to Stock-Pattern 😄 . I just released the latest Stock-Pattern.

You really need to start using virtual env to isolate your dependencies.

When updating Stock-Patterns, also update to the latest fast_csv_loader, so everythings work correctly.

Sure, i am already virtual using for all your repo. Will isolate the same for pattern.
Let me get the latest one and see as the flag one was also giving error.
Will check the same and update.

Thanks
Saurabh

Can you recheck the mplfinance and matplotlib versions. This is what I'm using.

matplotlib==3.9.2
mplfinance==0.12.10b0

This likely relates to GH issue #103

[BennyThadikaran]

I pushed a second update, adding a version check for fast_csv_loader. It will prompt the user to update fast_csv_loader.

I also updated the full dependencies in requirements.txt.

[cotton1234]

Its working now after installing as per requirements.txt

Thanks
Saurabh

Benny,

I noticed one more thing.

If i run bull_harm on monthly time frame it gives a stock. example allcargo with batu pattern.
Now if i run to find "ALL" it says no pattern.

(.venv) saurabhgarg@MacBook-Pro src % python3 init.py --sym allcargo -p all --tf monthly -c user.json
Scanning ALL patterns on monthly. Press Ctrl - C to exit

No patterns detected

If i give same patten which was detected it works fine.

(.venv) saurabhgarg@MacBook-Pro src % python3 init.py --sym allcargo -p batu --tf monthly -c user.json
Scanning BATU patterns on monthly. Press Ctrl - C to exit

Got 1 patterns for batu.

Should "ALL" not give this pattern or this is fine.

Thanks
Saurabh

If you use the interactive approach there is an double asterisk next to all with the note below: ** Excludes Trendlines & Triangles & Harmonics This is expected behaviour. Regards, Benny Thadikaran
