I created a 200 Week Moving Average tracking tool

Buffett

I've been looking for a tool that tracks long term moving averages, so I made one based on that old (maybe) Charlie Munger quote, “If all you ever did was buy high-quality stocks on the 200-week moving average, you would beat the S&P 500 by a large margin over time. The problem is, few human beings have that kind of discipline.”

Well, here's some back-tested data for that theory.

All pages are totally free. I tried to keep it as simple as possible while still supplying only the pertinent info to long term investing. I'm pulling all the stock data from AlphaVantage manually every week to keep it free. I plan on continuing to add more stocks, I'm just limited with AlphaVantage to a time-limitied set amount of data. It should account for stock splits properly.

If you have any stock suggestions, I'd love to add them, please list them if interested.
