Simple python app to drive Pimoroni e-ink displays with finance candle charts

bitbot's Issues

large log files break the html log output

uncaught (in promise) RangeError: Maximum call stack size exceeded
at readStream (config_editor.js:57:43)

volume chart has a lot of wasted space below it

improve the font used for the x and y axis.

📈 plot charts using the newer MPF API

The newer API has:

• Nicer looking candles (square rather than rounded)
• Offers more candle styling options (the white inside candles look esp nice for BW screens)
• Easy addition of moving averages
• Supports pandas data frame
• Simple volume chart
• Is actively maintained and accumulating new features

moving to this API would reduce the amount of customisation Bitbot needs in order to display a nice looking chart, and open up more options for future styling.

Make chart styles editable in the config-server

saves users the complication of ssh to edit chart plot styles

support for waveshare eink displays

I really like your frame with the 5.7 inch setup at etsy... if it weren't for customs.

Is there any chance the bitbot would also work with a Waveshare 5.65inch 7color e-Paper Module or a 2.7inch e-Paper HAT (with red/black/white) in connection with a pi zero?

test output is not consistent

needs to use consistent start date to create the same charts each time. creates extra commits and makes it harder to spot changes to plots in PRs

🪵 JS log reading causes config web-page to crash

Probably because the log file is growing too large, the recent release that splits the log into 2K chunks may have fixed this.

Timezone offsets are not being applied to the date axes

setting rc timezone to America/New_York makes no difference to the date axis.

KiloBitBot function of buttons

I got my 5.7 inky color eink and attached it to my pi zero which was running the waveshare test as installation from the image but that sadly didn't work. So I went to install it from fresh via CLI and that had no problems whatsoever. It started running and I was amazed! I absolutely love it. Thank you.
Now all I need is one of those nice aluminium stands (as an enhancement here it could maybe be an option if it could have a slight angle so it's not a 90 degrees stand but a 70 or 80 degrees angle for better viewing when standing on the desk - something like this one: https://www.thingiverse.com/thing:4664346 ).

It would be nice to be able to add functions to the buttons of the 5.7 inky display (the 2.7inch waveshare also has these buttons and maybe the same functions could be added here too):

• Button 1 press will start or stop the cycling between different currencies / assets of interest given in the config.
• Button 2 would start or stop the cycling between different timeframes (monthly, weekly, daily, 8h, 4h, 1h, 15m) so you can freeze a certain timeframe your interested in.
• Button 3 could on click change the style of the display (volume, volume overlay, ...)
• Button 4 would switch between the ticker mode and an only-picture-mode (loading the last set image) as a screensaver during the night or when away for vacation =)

The only issue I have is that I cannot get into the config webserver using a browser. Maybe I'll try configuring via CLI.

Unable to get it running using optionB.

• I used Raspberry Pi Imager to install Raspberry Pi OS Lite (32bit).

• I added ssh and wifi config files to the microSD card.

• I put the microSD card into a Pi Zero W and booted it up.

• I followed the steps in section B on: https://github.com/donbing/bitbot/blob/main/docs/app_install.md

• During step 2 I got errors suggesting I add the /home/pi/.local/bin folder to the PATH

  I ran step 4 and got the following errors:

    Traceback (most recent call last):
      File "/usr/lib/python3.9/runpy.py", line 197, in _run_module_as_main

    ImportError: libopenjp2.so.7: cannot open shared object file: No such file or directory

I added the above folder to PATH and I got the same errors.

I was able to use Setup Option A successfully.

🧪 Tests are overwriting the same image files

💡 Test output image names should include the display size in order to separate them out.
