BRETT Becoming Precarious

As you can see in the chart, BRETT is forming a kind of rising channel.
It's not an exact science, so it's a relatively crude rising channel so may be imperfect, however; if this channel is even close to correct, if BRETT breaks the apparent lower trendline of this channel, it will become very bearish, very quickly.
It has also been holding the 100 MA, but has broken below this.
