Since it was posted already I would choose "Queen: Bohemian Rhapsody". (more like a metaphoric song of trading)
I think I was 8 when I first heard this song. I didn't like it. I heard it over the years growing up. I think, the only time I truly appreciated this music was when I learned music at 25. Started playing guitar, drums, piano and singing since I was 14. I thought this song was just a total rubbish. Now, I think this song is one of the best song ever produced.
Its not your typical song/music. It contains different and multi-level of music. One could never imagine of mixing and incorporating so much into one and expect it to be an excellent piece of art. I mean, when you mix every color of paint, you would get a shitty-dark-brown color.
Trading is the same having multi-dimension. The ever changing and constant movement of transitions from one form to another (all happening in one trading session). And that's why a rigid trading plan will never survive such turbulent environment. A trading plan needs to accommodate and be able to identify every form of shift and transitions.
