GBPJPY - Sell because the formation of an triangle

If we look at Pierre's analysis we can see that in the next houers the market will go up. But when it touches the trendline it will go down again. As we can see, there's forming a triangle with a horizontal bottom line. An indicator for the market breaking soon or later the triangle in order to go down. But after the market breaks out, it will situate itself in an overselled-zone. An other indicator for the marking going drasticaly up.
I would like to hear your opinion about it.
