title: Trying to get posts stream from reddit filtered by keywords using praw
body: <p>I would like to get a live stream of posts from reddit filtered by list of keywords.</p>
  <p>I'm using if on the selftext but it looks like something is wrong and I don't know what.</p>
  <pre><code>subreddit = reddit.subreddit(&quot;all&quot;)
  ticker_list = [&quot;AAPL&quot;, &quot;AMZN&quot;]
  for submission in subreddit.stream.submissions(skip_existing=True):
  if submission.selftext.find(ticker_list) != -1
      print(&quot;Title:&quot;, submission.title)
      print(&quot;Description:&quot;, submission.selftext)
      
  else: 
      continue
  </code></pre>
