Redtide
My attempt to model stock...
Python 3.5+
Intro
If you are looking at this, chances are you were on Reddit. This is currently documented very very poorly. You have been warned. Hopefully, you just want to pull stock histories yourself, and if so, just scroll down and follow the steps. If you really want to know what else it does (i.e. retrieve live stock prices, dimensionality reduction, transformation, all that ML stuff) You will probably find much better resources else where. But, of course, you are more than welcome to look through the code. For now, I'm a bit too busy and streassed out by work to document anything thoroughly, so... have fun!
Dependencies
- Pandas
- Numpy
- PyTorch
- Scikit-learn
- Seaborn (if you decided to play around with the other stuff)
Only Pandas is really involved in scraping data, but since I import these at the top, you might want to have these so you don't get errors
Pull stock histories
1. Update AMEX, NYSE, and NASDAQ listing files.
- This is not a mission critical step, but it's a good idea to do to prevent getting too excited about a symbol that's already delisted or have repeated rows of the same data because it's delisted (the latter can be solved by more careful programming though).
- Register and download AMEX.txt, NYSE.txt, and NASDAQ.txt from http://eoddata.com/symbols.aspx (click the little down arrow icon next to "DOWNLOAD SYMBOL LIST")
- Replace the current AMEX.txt, NYSE.txt, and NASDAQ.txt files under redtide/data/ folder with the new files
2. Compile listing symbols.
ONLY if you updated the listing files in step 1, if not, skip this step
- Delete all_symbols.txt and excluded_symbols.txt under the redtide/data/ folder
- Navigate to the redtide/src/ folder and run the following command in a terminal.
$ python3 redtide.py -v -c
- This will check each symbol in the 3 exchange listing files to see if their data can be pulled from Yahoo Finance. If yes, they are compiled to all_symbols.txt. If not, they are compiled to excluded_symbols.txt
- When it's done, you'll see the new all_symbols.txt and excluded_symbols.txt under the redtide/data/ folder
3. Pull data.
- Navigate to redtide/src/ folder, and run:
$ python3 redtide.py -v -d
- This will take a long time. How long depends on the number of processors you have and your internet connection speed.
- When this is done, you will see a full_history/ folder under redtide/data/ that contains all the goodies (i.e. AMD.csv).
Other stuff
If you want to know some other options:
$ python3 redtide.py -h
