Testing what I've learned

Hi guys,

I’ve tried to test what I’ve learned so far by using tradingview.

I tried the Fib Retracement tool and a trend line on EURNZD.
In what I see the resistance got broken at 1.68143. It went up and entered the 0.382 Fib Level.
Then a doji appeared followed by a bearish engulfing.
Seeing this as a confirmation I would have entered after the bearish engulfing at around 1.68650 with a selling position.

Closing at 1.68250 would have brought some pip profits.

Now that I don’t really know if my analysis was right, I’m asking you if I was applying this right or if I was just lucky.

Thank you in advance.
