Launching tstock would produce error as shown :

Traceback (most recent call last): File "/usr/bin/tstock", line 33, in sys.exit(load_entry_point('tstock==2.1.2', 'console_scripts', 'tstock')()) File "/usr/bin/tstock", line 25, in importlib_load_entry_point return next(matches).load() File "/usr/lib/python3.10/importlib/metadata/init.py", line 162, in load module = import_module(match.group('module')) File "/usr/lib/python3.10/importlib/init.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "", line 1050, in _gcd_import File "", line 1027, in _find_and_load File "", line 1006, in _find_and_load_unlocked File "", line 688, in _load_unlocked File "", line 883, in exec_module File "", line 241, in _call_with_frames_removed File "/usr/lib/python3.10/site-packages/tstock/main.py", line 3, in from .core import main File "/usr/lib/python3.10/site-packages/tstock/core.py", line 7, in import numpy as np ModuleNotFoundError: No module named 'numpy'

Not every market generally uses green for up and red for down. For instance, China (excluding Hong Kong) and Japan conventionally use red for up and green for down, and South Korea tends to use red for up and blue for down. Investors accustomed to the prevalent chart colors of those markets (including me) may find it difficult to adapt to the "green up, red down" style. Therefore it would be nice to allow users to customize chart colors.

I've allowed users to set the colors of positive and negative candlesticks as green, red, or blue by adding options --upcolor and --downcolor. This caters to the needs of investors from China (excluding Hong Kong), Japan, and South Korea.

When I start something line alacritty -e tstock btc, new window with chart appears for half of a second and closes immediately. I use dwm + alalcritty. I did the same operation with st and got the same result.

When using with watch, like watch --interval 20 tstock btc, tstock seems to fail while detecting the screen size:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/bin/tstock", line 8, in <module>
    sys.exit(main())
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/tstock/core.py", line 428, in main
    opts = parse_args(parser)
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/tstock/parse.py", line 47, in parse_args
    t = os.get_terminal_size()
OSError: [Errno 25] Inappropriate ioctl for device

Maybe it would be better to use a config file ~/.config/tstock/config to put in the API key. This way it would work from every shell and I think it is simpler to edit a config file than to add an environment variable. Also the config could be used for other things in the future.

For example, $ tstock btc -c UYU works fine but $ tstock btc -c uyu doesn't. Output when trying to use the lowercase ticker:

  File "/home/mcbruno712/.local/bin/tstock", line 8, in <module>
    sys.exit(main())

    opts['currency_symbol'] = currency_symbols[args.c]
KeyError: 'uyu'

hi, I am using Git Bash and after installing tstock with pip and setting the Alphavantage API key (for anyone interested in how to do this see here) the program fails to print out the graph.

I am getting UnicodeEncodeError: 'charmap' codec can't encode characters in position 7-8: character maps to <undefined> error. i have attached the screenshot below. Looks like the error is at line 379 from core.py and it might need fixing by forcing UTF-8 encoding ( I am not sure).

Hey, could you make a Dockerfile that will run the make build? It would be much simpler for people to install without having to worry about required compiler, settings and libs.

This commit switches from calling the curl binary on the command line to using the proper C API for curl.

There are still a bunch of TODOs, but nothing seems to be broken as far as I can see

The simple command format tstock {stock name abbreviation} no longer works as AlphaVantage has made the TIME_SERIES_DAILYfunction premium only. The TIME_SERIES_DAILY_ADJUSTED function is not premium only and works fine as far as i can tell.

To make tstock use TIME_SERIES_DAILY_ADJUSTED change line 148 of core.py from api_function = 'TIME_SERIES_DAILY' to api_function = 'TIME_SERIES_DAILY_ADJUSTED'

The candles on the chart seem to be about 10% lower on every stock. Probably the prices are right, but the y-axis labeling is somehow off. I have everything in USD, but it could also be that it somehow gets converted to EURO.(Cause the exchange is about 10% lower)

The currency will always be displayed as USD, even if the data is from a foreign market of a different currency. Additionally, it will be displayed as USD even if it is a unitless measure, like an index.
