Two psoitions are thinkable:
Long: Stopbuy @ 154,10$ - TP 169$
Short: Stoppsell @ 142.5$ - TP 130$
The Zone between these mentioned levels seems to be neutral from a procycical view. - here is no Action needed.
If u prefer anticyclical positions, a shortposition at the actual Level could be interesting to short IBM
In my Chart i have illustrated the two procyclical positions
On the other hand, you can try to short the upper edge of the flags Body. here should be the sl a bit above the flags Bodys uper edge, for example @154,5.
As Long as IBM is trading below your illustrated trendlines, a short Position has a right to exist :-)
