Coolman, watch for the reaction at those levels on your hourly chart. If there is a strong move through a level, then most likely it will head to the next one. For the most part, the level gets hit, then bounces off it which amounts to at least 38.2% of the level it just came from. If it is a continuation, where price action goes all the way through it without the bounce, then there will be a move back to that level after the next level is hit. In the event of a strong spike that would start the week, they will take on a different perspective.
Even they I know their functionality, I still use them as a confluence with the rest of my methodology. As an example, I mentioned in a previous post I doubt the R1 would be hit this week, because of all the cluster and significant R activity that precedes that level. That is also the reason the S2 is favored to be hit. If it makes it half way to the R1, it still will drop 2 1/2 levels to the S2. Minimum expectancy is a 3-level range.
BTW, I see you are relatively new. Welcome aboard!
