However, if either of their lines hold up any kind of reactive pattern to price, either as support/ resistance or as a line of symmetry in which price swings roughly equally above and below, and price ends that relationship, then the has served its purpose of demonstrating a "change of price/ time behavior" and is cluing us in to a potential major price and perhaps even change of long term trend.
It may be necessary to play with different price levels to find a that fits the current price behavior. Here, I use the all time high as a to both to the , but it may not be a good for either of them. That, we may not know for sure until we get some more price action to build our from.
I realize that not everyone follows the same set of rules when it comes to pitchforks and their validation parameters.
