COS is moving in a huge Falling Wedge pattern and in the next few days it will reach the most important support zone at 53-57sts, which is the confluence of the bottom edge of the Falling Wedge and the lowest price zone of the COS. So there's definitely a strong buying force here and we could buy in this zone.
The highest target of this turn is 105-110sts, but COS needs to break the 70-75sts resistance zone, and there will be a correction at the 90sts.
But exit the COS if it falls off 50sts
