How to Objectively place Fibonacci Retracements

I've seen people place retracements in interesting ways and just want to show an objective way to place your retracements.
You need a top, a bottom, and a corrective wave or reversal that you are analyzing.

Now, fibs are everywhere and you can place them however works best for you and there is no ONE way,
but this is for people who want to approach learning fib in the most objective way possible.

I believe it is smart to have strict rules in your trading system and rules that align with what most pros are used to following.
Good luck,
