Hi Tony -- This is probably not the answer to all the questions you asked, but here is afl code to plot the pivot points for tomorrow one day ahead.
---------------------------- // PivotPoints.afl // // Traditional pivot points. // Thought by some to indicate levels of support // and resistance. //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) P = (H + L + C) / 3; R1 = (P * 2) - L; S1 = (P * 2) - H; R2 = P + (R1 - S1); // P + (H - L) S2 = P - (R1 - S1); // P - (H - L) Plot(C,"C",colorBlack,styleCandle); // Displace the plot of the pivot points one bar // to the right. // Pivot points are based on the current bar, // but are thought to provide indication of // support and resistance for the next bar. // Displace=1; Plot(R2,"R2",colorRed,styleLine,0,0,Displace); Plot(R1,"R1",colorPink,styleLine,0,0,Displace); Plot(P,"P",colorBlue,styleLine,0,0,Displace); Plot(S1,"S1",colorPaleGreen,styleLine,0,0,Displace); Plot(S2,"S2",colorGreen,styleLine,0,0,Displace); //Figure 8.5 Pivot Points ------------------------------ Thanks, Howard www.quantitativetradingsystems.com On Thu, Feb 21, 2008 at 3:24 PM, Tony <[EMAIL PROTECTED]> wrote: > Hi, > I am hoping to have someone point me in the correct direction. > Below is my intraday code to compute tomorrows pivot points and > S1,S2,S3 > R1,R2,R3 > In the title line of my intraday chart is displayed daily cummulative > quotes for close open volume etc and tomorrows pivots. > see code below > > even though my price graph is in 5 minute timeframe increments i > switch to a daily time frame to compute yesterdays close, high and > low and am able to compute the pivots for the following day correctly. > > i have 2 questions which i hope someone can answer: > 1) i need to click twice on a bar to get the values to display on > the title for price chart (the first click shows most of the fields > as empty values). why? may i get around this? > 2) i tried using the plot command(see last line of code). i expected > a single straight line plotted on my intraday chart ( a different one > for each day).
