A technical explaination could be;
I cut it in half because it was a 1 day bottom anomaly, which corrected on the open the next day. Saying trend reversal.
But in reality I didn't think that deep. I just drew the trend I saw and sometimes prefection is not seen in every days action.
Remember the goal is over all mindset accuracy, not daily fluxes or over reaction surges. That's why I don't include candle tails in most chart lines, unless there are a series of them forming a concensious.
Basically Charting is more of an art form then science. I'm the artist. For your charts your the artist. Every chartist will not produce the exact same chart. But normall good ones come up with the same results. Theres gray in charting, not black & while. Else every target would be exact and hit perfectly.
