SP 500 head and shoulders pattern

• SP 500 is forming a head and shoulders pattern in 2 day chart.
• The right shoulder should be in place when the index trades above 1135-1145.
• The right shoulder in a head and shoulders pattern can be lower than the left shoulder also.
• But any price action 1155-1160 should be taken as pattern invalid. Because There is important resistance at 1150. And if that is broken bulls may aim for 1200.
