Regarding standard D-point Fib targets. As to best of my knowledge, harmonic patterns have been studied in details in the beginning of 90-es by relatively narrow circle of professionals. Later, the technology widespread into wider public, and as usually happens was "abused", which led to patterns partial destruction. As a result, nowadays, patterns do not work as perfect as used to be, and one need to know current statistics of realization of D-point.
That's what I heard from another traders.
