Please Help me understand this... They announced they are going to bust any trade outside of +60% to -60% of the average price during the day... They've been all over the news saying PG trades will be busted. Average price in PG today is about $60 The LOW in PG today is $39.37 $60-$39.37= $20.63 drop. $20.63/60= 34.38% move, How are they justifying busting these trades?!?
