esignal easy formula help please

  1. ok, i'm not much of a programmer. i understand some basics, but that's about it.

    i made a formula for esignal that works, but it is plotting it in the wrong place. i made a simple formula to explain my problem:

    function preMain()
    function main(Price, Periods)
    var close = getValue("Close",0);
    var close1 = getValue("Close",1);
    var close2 = getValue("Close",2);
    var close3 = getValue("Close",3);
    var close4 = getValue("Close",4);

    var ma = ((close+close1+close2+close3+close4) / 5);

    return ma;

    the above formula calculates a simple 5 period moving average. however, when i have esignal do a 5sma on its own and i run my formula, my values are the same, but my 5sma gets plotted 5 days ago. lol all i want is to get the above formula to line up exactly like a 5sma done by esignal.

    once i see what my problem is, i will go back and fix my original idea.

  2. here's a chart that shows my problem..

    the black line is a 5sma done automatically by esignal.

    the blue line is a 5sma done by the formula i made.

    i just want them to match up, but for some reason my formula is lagging.
  3. I like your blue one better, it appears to predict the future:D :D
  4. hehe that's because my blue line is based on recent bars, but then it is getting shifted to the left by accident. :mad: :confused:

    the getValue() function's 2nd parameter should be negative if you want 'bars ago'. It's positive if you want 'bars in the future', which is why your SMA is charted 5 bars behind the current price (since eSignal cannot see the future just yet, that's coming in version 8.0 ;) ).


    getValue("close", -1)
    getValue("close", -2)
    etc ....
  7. dude! thank you so much! that's all i needed! all i had to do was change those positive numbers to negative........this is great.

    THANKS! :D :cool:

    Esignal will help you write anything you want. I requested some custom Keltner channels and they sent me the formula a few days later. Inserted it in my formulas library and bingo.
  9. how do you request them?
