Code donation

For a couple of years i ran "lovac", the "low volume accumulator".

It was a (flask based) stacking app which used the bitstamp API to get prices, place Marketorders on a (daily) basis and, especially proud: a buy-the-dip feature. So the app could detect a drop in price and even show it graphically.
I shut it down some month ago and i'm now happy to donate the code if anyone is interested:
https://gitlab.com/lovac/lovac-app
The code used SQLAlchemy and, for the statistical things pandas.

Here are some places in the code which might be interesting:

• testing whether the price is dipping via specific Bollingerbands: https://gitlab.com/lovac/lovac-app/-/blob/master/tests/lovac_services_tickerdata_tests.py#L56
• Various methods to import csv-data-files into the DB: https://gitlab.com/lovac/lovac-app/-/blob/master/lovac/tickerdata/__init__.py (i used https://bitcoincharts.com/charts/chart.json for that)
• The statistics for the bollinger-bands: https://gitlab.com/lovac/lovac-app/-/blob/master/lovac/tickerdata/statistics.py
• THe graphical representation took me some time. If that's a request at some point in time, i might be able to set it up again:
  
  The red bubble represented the buy-the-dip. The bigger the bubble was, the more it bought.

Feel free to close this issue but maybe you find it interesting. Also happy to answer any questions or setup a call.

This looks interesting. In particular, I'd like to see some of the price graph stuff you have.

I tried taking a look at it https://gitlab.com/lovac/lovac-app but I'm getting a 404? Did it get deleted there?

Oh, sorry, now it's visible. The graphing is based on d3 (version 4, current is 7.x). I copied it from one of the brushing examples which i can't no longer find. Today i'd probably took this one:

Here is the meat of it:

Data is injected in line 94/95

The maintenance of that project took too much effort for me especially the dependencies. That's the reason i gave up and there also in the meantime lot of better stackingsats alternatives on the market. It might not be that easy to get it to run without some changes.
