people can't make it work on the daily but let's throw dozens of lines on an intraday chart.
imo the only number that works on the daily consistently is the halfway back, which isn't a fib number at all. However, while I am not a fib guy, there does seem to be evidence that intraday these levels can be worked. I'm usually trading 3,6, 10 points or more on a trade rather than a few ticks. So for me, the only level I watch is the midpoint highs to lows as a 4 tick reaction off a fib number doesn't interest me. But I think the OP has a workable strategy that someone nimble of finger and disciplined as well could probably work for a profit. I would think that the OP would concede he is basically playing for a small reaction, and doesn't impute any special magical powers to fibs like some fib wizards do.
