As Internet says, the Bat pattern was discovered by Scott Carney in 2001 (see: http://www.harmonictrader.com ).
B point must be between 38.2 and 50% retracement of XA. CD is usually 127% of AB. D point lends at 88.6% retracement of XA. It's great looking harmonic pattern with very precise and super small StopLoss, and it is what counts in the Harmonic Trading.
Position of the B point is crutial. Based on B point position we look for the Gartley or Bat pattern.
Following video compares both patterns:
