Predictions (just for testing, not a financial advice)

These are backtest results for the strategies I have tested (just the abstract method at the moment, you can't predict lotery lol)

random strategy

predicted: 20 / day (20 tickets perday or 200,000 vnd) predicted corrected:

How project works

Since there are many people asked, I write this section.

Schedule

The project is schedule automatically via Github Actions, run a script, fetch data and auto commit to Github. No server is required, I don't need to do anything. Details in workflow file

How crawling works

I just inspected network packages sent between browser and server to find out how data is fetched and replicated that in Python code.

Install

via pip

pip install -i https://test.pypi.org/simple/ vietlott-data==0.1.3

cli

project provides two cli

crawl

Usage: vietlott-crawl [OPTIONS] PRODUCT

  crawl a product with a given run date or from/to index page 

Options:
  --run-date TEXT
  --index_from INTEGER  page index from run since we crawl by pagination the
                        pages
  --index_to INTEGER    page index from run since we crawl by pagination the
                        pages
  --help                Show this message and exit.

Backfill missing data

Usage: vietlott-missing [OPTIONS] PRODUCT
