Is 0.886 fib an OB level or are we just speculating? well in short idk😉 you find out on your own, i have been back testing this thing for the past few weeks and almost in all cases im seeing some correlation between the two, but why? well idk😂 its basic math at this point i mean order blocks are areas where price made some form of lows or highs, so at those areas if price revisits there might be an opportunity for good reaction those areas are almost in all cases at the 80% of the move up.

Why do i think 0.886 is better than OB?
OB is dynamic, you don’t clearly understand which OB to use 15m 30m etc…. why not 25min (this is something i had in mind when i first learned about OB). While in the case of fib its an exact level, we expect price to move at a specific value instead of a dynamic area.

is 0.886 something you made up?

Keep in mind this is just an observation so DYOR and backtest before you come to a conclusion.
