medved Quotetracker for Pivot Points and alot of other charting indicators. Primarily for realtime streaming quotes from your broker, but it may work with prophet.net delayed streaming or other service that only requires free registration to recieve delayed streaming quotes.
since it's tuff to see...for the attached SPY, the pivot point for this month was/is 88.18. For SPX it is 879.26
Pivot points can be adjusted to multiple parameters just like most other indicators. I am using the default parameters which are based on the previous month's intraday highs, lows and averages, I think
An 'alternative investments' broker I used to trade futures, options, and commodoties with based most of his trades on pivot points. Note: He recently lost -54% in october 08, and -34% in nov 08.
How to Calculate Pivot Points
There are several different methods for calculating pivot points, the most common of which is the five-point system. This system uses the previous day's high, low and close, along with two support levels and two resistance levels (totaling five price points) to derive a pivot point. The equations are as follows:
R2 = P + (H - L) = P + (R1 - S1)
R1 = (P x 2) - L
P = (H + L + C) / 3
S1 = (P x 2) - H
S2 = P - (H - L) = P - (R1 - S1)
Here, "S" represents the support levels, "R" the resistance levels and "P" the pivot point. High, low and close are represented by the "H", "L" and "C" respectively. Note that the high, low and close in 24-hour markets (such as forex) are often calculated using New York closing time (4pm EST) on a 24-hour cycle. Limited markets (such as the NYSE) simply use the high, low and close from the day's standard trading hours.
