title: How Auto bidding works in auction sites
body: <p>I am having a question about Auction website. I am not asking about entire process as I know that's impossible to answer here. I just need the lead with explanation</p>
  
  <p>Explanation for Autobids booking :-</p>
  
  <p>If user gives the High and Low value for bidding price with number of bids to place in that range. The system should place the bid automatically even the system in hibernate.</p>
  
  <p>For example :-</p>
  
  <pre><code>High (Bid from) : 10
  Low  (Bid To)   : 20
  Number of bids  : 5
  </code></pre>
  
  <p>Let us take current auction price is $11 .Then the machine is active, so it should place a bid with randomly generated time interval.</p>
  
  <p>I did these closely in jQuery. But it should work even it hibernate.</p>
  
  <p>This technique is already used in many live auction websites like</p>
  
  <ul>
  <li><a href="http://www.beezid.com/" rel="nofollow noreferrer">http://www.beezid.com/</a></li>
  </ul>
  
  <p>If you login then you can see the machine in auction details page. 
  If you have any previous experience please share it. Does Cron job make sense?</p>
  
  <p>My table structure is mentioned <a href="https://stackoverflow.com/questions/6218166/mysql-select-switching-rows-for-every-execution">here</a>.</p>
  
  <p>What technique is used for this? How can I do this?</p>
