Awright then, I am beat today. Lack of sleep I guess. I want to make mention of my personal bias are regards the "proprietary" formulas and variations on Standard Floor Pivots (Including Carmarilla).
After all these years, seeing God knows how many versions of pivots, I believe that it is not the pivots or the formulas that matter. What matters is how the trader uses them. I realize some will think this statement trite. Stop and think for a moment. After you try out some of these variations, you will see the differences are marginal. But when the bell sounds, what matters is how price acts when it approaches, tests and either takes out the pivot, or fails and retraces. A talented trader decides what to do based on what happens immediately before and after price touches the pivot. If for example he/she sees momentum build as price approaches the pivot, and the pivot level is taken out forcefully, it is sending you a message. If price touches and backs away or penetrates but cannot close above the line, again it is telling a different story. These are just a few concepts that are important, in fact more important in my view than the actual formula.
People who look at these trading tools should remember that good traders, especially traders who use discretion, use everything they have to make good decisions, including experience, intuition, confirming indicators, etc. Without trying to be to dramatic, I believe that trading is a very competitive and challenging pursuit that pits trader against trader, and the guy or girl who out thinks the others and makes the best decisions wins.
Good luck to all of you.
