Confused on Harmonics. Any help?

Okay, So... which harmonic type did I choose here? Tradingview does not show the fib height breakdown between XA, AB, etc; but instead shows the XB, XD, BD, AC lengths...

Does anyone have any good websites, video tutorials, or books to read to better understand and practice harmonics???

Wish I could have been more clear what I was predicting on this one
