Short squeeze may happen if:

• Squeeze Momentum Indicator shows a pumping fase is just about to go into a release of squeeze: a (dark) green followed by dark green.
  
• Squeeze Momentum Indicator has high levels near 5225 or above.
  
• The accumulated values of the ratio between longs and shorts within a pump period of shorts is almost the same as the reference: the red area's must fit each other with low variance.
  
• investopedia.com/terms/s/shortsqueeze.asp : the short-interest ratio is falling lower than 0.9 to 0.75 as in the reference
