This a nice example of how timing works. We watch timing to anticipate possible changes in trend. In this case we had the coincidence of 4 time relationships between 3/4 and 3/5. Since NDX was trading straight down into these cycles, we were anticipating a possible low to develop.
This along with some Fibonacci price parameters told us to watch for the possible reversal back up.
So far we have seen a rally of 909.48 from the 3/5 low made directly within this time window. Coordinating time and price....followed with a buy trigger is the way to go with it!
