SELL GBPUSD INCOMING

Hi guys, i'm not used to do this kind of mid-term chart but there is maybe a gooood sell opportunity for GBPUSD !
As you can see on the chart there is 2 trendline.
The RED is one a trendline since 3 december 2020, the price respected it few times too.
There is another one, the PURPLE one who the price also respected this one few times.

Now, if the price reject the red line, we can except to see the price break the upper purple trendline and go short by far.
If the price reject the purple line, it'll we a short position for the short term

There is 2 different option, but what i can say that is the price will maybe go down in the green circle area !

What do you think ?
Have a nice day :)
