Some explanations are needed here:
The floor traders pivots are based on the sum of yesterday's (close+H+L)/3 (the "PivotPoint"). The traders on the floor of the S&P watch that line today and almost always gravitate back to it. "Support" and "Resistance" lines are created based on that line and are used by them to aim for and change direction or daily philosophy e.g. Supp = PP*2 - yesterdays H and Res = PP *2 - Yesterdays Low. They are different lines depending on if you use daily charts or intraday charts. They are fixed at the open and stay that way for the entire trading day and stay that way the whole day moving across the chart. In electronic trading such as FOREX, there are no Floor Traders and this is not as reliable as in the Futures markets. The "Market Makers" here that manipulate the prices that we follow are the Big International Banks and I doubt that they follow these type of pivots as their buy/sell philosophy. Thus they are less important as Supp/Res lines.
Pivot Points are direction changes that we see when a Trend in one direction changes to the opposite way. There are Minor and Major Pivots. A minor pivot occurs within a major trend when traders are cashing out and taking some profit. The the trend resumes. A major pivot occurs when the is exhaustion in a particular direction and there are no more takers, so it is "overbought" or oversold" and changes directions. Those tops and bottoms are the true support and resistances because the market tell you that that is where it is happening.
To see these, Tradestation gives you and Indicator called ZigZag which shows you major trend direction changes. Most people do not like these types of lines on the chart. They also give you a Showme indicator that plots as dots and there are three types that you can try: Under the <Showme> menu when you right click on the chart AND CLICK ON <Insert Indicator> there are "Pivot High" "Pivot Low" / Pivot Rev Gen - Dn Pivot Rev Gen - Up / SGPivotHighBar SGPivotLowBar. You can make them show more or less pivots on the chart by changing the default from e.g. 3 in Pivot High and Low to 5. The math is complicated, but you should realize that there is a delay with all of these indicators because it has to happen first before the program can calculate it. A Pivot High or Resistance is a High which is lower than a previous high which was higher than that previous high; and a Pivot Low or Support is a low which is higher than the previous low which was lower that its previous low. So it takes a minimum of 4 completed bars to calculate.
If you want a Supp Res indicator that plots them as horizontal lines for intraday charts, I have one that I wrote that might work for you, but it has to be fiddled depending on how slow or fast you want it to show up.
Hope that this helps.
