I can't download BTC/USDT from binance,could you send me the data from mail?

[domodo2012]

hi, i'm interested in basana，but when i follow your quick start,I couldn't download data from binance with the command below:

python -m basana.external.binance.tools.download_bars -c BTC/USDT -p 1m -s 2021-01-01 -e 2021-01-31 > binance_btcusdt_min.csv

the web is banned.
could you send data to me from mail,or upload the data on github,please ?

thanks

More on this issue, I believe it's due to the encoding the Windows cmd/powershell writes the file to.

I had to modify the encoding of the file using this script:

import os
import sys
import chardet


def convert_file_to_utf8(file_path):
    # Detect the file's encoding
    with open(file_path, 'rb') as f:
        data = f.read()
    detected_encoding = chardet.detect(data)['encoding']

    # Convert the file to UTF-8
    with open(file_path, 'r', encoding=detected_encoding, errors='replace') as f:
        data = f.read()
    with open(file_path, 'w', encoding='utf-8') as f:
        f.write(data)

    print(f'{file_path} converted from {detected_encoding} to UTF-8.')


if __name__ == '__main__':
    if len(sys.argv) != 2:
        print('Usage: python convert_to_utf8.py <file_path>')
        sys.exit(1)

    file_path = sys.argv[1]
    if not os.path.exists(file_path):
        print(f'Error: File "{file_path}" not found.')
        sys.exit(1)

    convert_file_to_utf8(file_path)

Which is run via python convert_to_utf8.py binance_btcusdt_min.csv

Hey, sure sorry I do now realise my issue was different.

I also modified line 82 of samples/backtesting_bbands.py: exchange.add_bar_source(csv.BarSource(pair, "binance_btcusdt_day.csv", "1m"))

When I was in the debugger, I was getting weird characters for the row_dict. The issue was that the csv file which is saved from the first command was being decoded maybe in UTF-16, so when it was being read back in it was having issues reading it. Hence, the script that converts it fixed my issue.

That last parameter, "1m", should be in sync with whatever you used when you downloaded the bars.

I've fixed the issue by changing the encoding of the file binance_btcusdt_day.csv so no need to worry.

@gbeced I'd suggest in the docs, use bitstamp for example, python -m basana.external.bitstamp.tools.download_bars -c BTC/USDT. Binance is banned for access from the states.
