Cool! I will try to come up with some more theories in the mean time. Something that I think I have lacked is screen time, which I think is not very common. With all my time glued to research, I hardly ever actually look at the chart, and well, visuals are where we get the idea of patterns from.
In the meantime, EU has been somewhat.. close to historic. News and “looming moves” aside, which are not accounted for, these past couple days have been interesting. It has happened a couple times, but seeing consecutive tops and bottoms with just a single potential transient zone is quite rare. To happen three times in a row would start to be a bit crazy. I wonder if this kind of categorization, if capable of being done on a smaller time frame and scale, would allow classifying extended states a bit easier..
For that reason alone( P(not 3 times in a row)) I have a long bias on EU, to at least break the current PTZ. Given how my pivots work, I can pretty much always get 1:1 RR, so as long as the logic is sound, this seems like a good bet.
