I have recently came across a site stating price usually retraces to the 50% fib before heading upwards or downwards. In this case the weekly pin bar
. I tested it out and what do you know? 50% fib literally sits on my past resistance lines. Boy oh boy will this be interesting to see.
This is for future reference.
