title: Where can I find extra resources on how to use Quantopian?
body: <p>I am sure you all know <a href="https://www.quantopian.com/" rel="nofollow noreferrer">Quantopian</a> (I love it!!).</p>
  <p>Even though I am pretty good with Python, I am still having trouble writing a full algorithm (I am trying to write one using Fundamentals data).</p>
  <p>I have successfully used pipeline to get the stocks that I want, but am having trouble with writing the buys and the sells. Specifically, how to tell the program to buy this stock with some logic behind it and how to sell (the same or some other) stock.</p>
  <p>I have gone through tons of resources, checked out other users' algorithms, went through both Quantopian and <a href="https://www.youtube.com/watch?v=RxjIOXstxCk" rel="nofollow noreferrer">non Quantopian</a> resources but still having trouble. Do you have any suggestions for other resources?</p>
  <p>P.S. the link above is this guy 'sentdex'. His tutorials are the best!! It would have been fine if Quantopian didn't upgrade their systems, so unfortunately his tutorials are out of date now.</p>
