Fibonacci Retracement

[mywife]

Hello Coders,
I'm new here and wanna learn
I got question and already answer from somebody,
and here I have a question, how to arrange the block, using Fibonacci Retracement, from lower low to breakout candle? Please

@mywife Some more info would be appreciated. I see the low is the lowet price in the image, but I don't see the logic of that 100% level position. Where is it based exactly? And why there?
