The Most Profitable Trading Pattern You Will Ever Encounter

Hello everyone, could someone please list all the Fibonacci retracement levels they use for this system? Also, i’m wondering how far back in time should I go when looking for highs and lows? I use Metatrader 4 if that helps. Lastly, I have attached a picture of USD/JPY 4 hour chart. On March 18th around 4:00 is when the EMA’s crossed and stoch matched it. The trade went down later after going up a bit. Would I stay in the trade until the EMA’s crossed again?
