title: IMPORTDATA gets lots of errors because I am trying to load many cells for stock quotes
body: <p>I have a Google Sheet with 220 'importdata' functions where each one is pulling a stock quote off a website. The function is just a simple:</p>
  <pre><code>importdata(&quot;http://&lt;URL&gt;/&quot;&amp;A2)
  </code></pre>
  <p>where A2 contains the symbol like 'GOOG' and the <code>&lt;URL&gt;</code> is the website's URL.</p>
  <p>With 220 of these importdata's, I get the error:</p>
  <pre><code>&quot;Error Loading data may take a while because of the large number of requests. Try to
  reduce the amount of IMPORTHTML, IMPORTDATA, IMPORTFEED or IMPORTXML functions across
  spreadsheets you've created.&quot;
  </code></pre>
  <p>The errors never go away even if I wait a long time.</p>
  <p>See picture showing just a small section of the sheet.</p>

  <p>Is there any way to fix this? I would like to put in a random delay for each of these quotes from 1-5 seconds which would fix this problem but I don't know how.</p>
