Hi Swingscalp, welcome to the forums, you too psyogi -

For your questions - -
1. Andrew's forks happen everywhere, and if you can't see one in market you are looking out, if you zoom out a couple of time frames you'll see it. The times that they don't work are in an accelerating trending market. Markets that are trending strongly don't swing so much, so price won't often reach the andrews target.
Are they a self fulfilling prophesy? Probably, particularly on the smaller time frames. I think there are plenty of pros using AP and trendlines/channels exclusively.

2. AP sets up all the time, at least once a day in ES I'd say on the lower timeframes. As you train your eyes by applying it, you'll see.

PSyogi - - In that chart I just posted it was a different pattern than AP, called a wolfe wave. Tasuki and I go on yakking about that on another thread. WW are more subjective and require a deeper level of understanding of market geometry.
I've been actively playing this particular pattern, it's working out pretty well.
