Quote from dkm:
The highlighted bar (10:05) shows decr red vol and lower price so we expect change i.e. price up. Price on bar 10:10 does indeed go up, as anticipated, confirming change. The 10:15 bar continues up, with a close more lateral than up, and decr vol ,so one might then expect change. The 10:20 bar however continues up, on increasing vol, not as expected in terms of the Jokari window. With price up and increasing vol, I would expect the next bar to be up. However, on the 10:25 bar we have lower price on incr red vol, not as expected, so this must be change. I am now anticipating price to head lower on the next bar. However, the 10:30 bar gives us higher price on increasing vol, not as anticipated with the Jokari window, so change again.
The Jokari window appears to fail several times. Is my interpretation of the Jokari window incorrect or are we actually seeing it fail? Is this just another way of saying "we didn't see what we were expecting therefore we have change"?
Your interpretation of the Jokari window is correct, although you should take into account the two resolution levels at which we can apply it in your example. Doing bar to bar analysis on the tree level we can indeed see increasing volume and increasing price and would therefore expect price to go up. If we look at it from the resolution at which you drew your gaussians we see decreasing volume and increasing price and we expect price to go down.
What happend here is that price is in a non-dominant or retrace from 10:05-10:20 as indicated by your gaussian. The decreasing volume on the highlighted bar already provided a clue that a retrace might be next. Price then proceeds it's course in the dominant direction on higher volume on the 10:25 bar. This is what we expected price to do if we apply the Jokari window to your gaussians.
The interesting thing here is that the 10:25 bar (the bar you labeled p3) is a FTT. If we look at the two preceding bars (10:15 and 10:20) at the (finer) tree resolution we can indeed distinguish a situation where price does something unexpected according to the Jokari window. I'd say that it's quite fitting that the bar where price did something unexpected is also the bar where price fails to traverse

I'm not sure if FTT's are often preceded by a situation such as this but I'll make a mental note to be on the look out when encouter it. There's a possiblility that we've found a good indicator for an upcoming FTT.
