Every time it gets to support it first moves up to about 13200 and then comes down again to make a double bottom before moving up much higher. It has already made the double bottom so you will be lucky to get a third touch.It might happen but I think it is safer to get in now.
Two factors at play with MTN , namely currency (Zuma) and oil price.I will wait to add more. I do however agree with your technical analysis.(omo). If Zuma strikes, then this share is going down to R107-R109, gross of dividend.
