I was wondering if anyone had any statistics/knowledge on determining when a short squeeze might be coming up?  I find myself thinking about this more often at the end of the day but I'm sure any information would be useful at anytime. 
  
Many times within the last hour I want to take a trade but the potential for a short squeeze/cover on a stock that dropped significantly or even a sell off on a stock that gained makes me hesitate. 
  
I was wondering if anyone has any suggestions on how to determine when these two actions are more likely?  Maybe some details on float, gain/loss, percentage short(for stocks that are down), and/or volatility? 
  
Thanks in advance and look forward to you comments!
