All of the "market Profile" and pivots and other crap is good and all, but being able to understand "the story" and visualize what is really happening, is critical in predicting this stuff.
Market Profile is the 'visualization' of the 'story' by its very definition. The High, Low and Close of the previous day are also part of the story and all traders better be able to visualize them.
Now, adding the previous day's H, L & C together and dividing by 3 and then multiplying and projecting those totals above and below the market is not part of the story. And yes, they could be construed as crap.
In other words, trade data that creates the market profile and shows one clearly where traders have accepted and rejected value along with the previous day's H, L & C, trade data ARE real. Sup/Res projections above and below the actual trade data based on simple division, multiplication and addition are NOT real.
The market does have constants.
