One extremely useful concept in trading is the notion of equilibria. FV is at it's core based on it.
On the other hand, we see markets bounce and reflect from prices, regardless of where FV may be at that point. One notion that I have not incorporated into FV is the notion of multiple equilbria. This notion of multiple equilbria explains a wealth of stylized facts of technical analysis, for example, levels, support and resistance. I get around this fact by getting the values from technical analysis, and then deciding how likely that level is to hold/resist.
It would be better if I had a more quantitative way to do this, but the technicians lines work surprisingly well. The nice thing is that I finally have a quantitative reason as to why they work - more, there is actually a body of theory as well. To the trader, they would just say, "I told you so." But when you don't understand the reason something works, it is hard to put real money behind it from a philosophical point of view.
