  • linear regression breakout.efs

    is there any way to modify this efs so that it will alert if the price goes above a standard deviation line above or below the actual regression?

    thanks

    Hello dirtypoolman2,

    Please post a copy of the formula and I'll take a look.

      efs for Jason

      Jason:

      It's a copy of the code found in the program itself, listed below. Repeating, I'm looking for the routine to alert me when the price trades above a standard deviation line above or below the regression line.

      Thanks

      //
      // Fires an alert when the price moves below or higher the lower or upper Linear Regression lines.

      //{{EFSWizard_Declarations

      var vLinReg20 = new LinearRegressionStudy("Close", 20, 1);
      var vLastAlert = -1;

      //}}EFSWizard_Declarations 10369


      /**
      * This function is called only once, before any of the bars are loaded.
      * Place any study or EFS configuration commands here.
      */
      function preMain() {
      //{{EFSWizard_PreMain
      setPriceStudy(true);
      setStudyTitle("Linear Regression Breakout");
      //}}EFSWizard_PreMain 8010
      }

      /**
      * The main() function is called once per bar on all previous bars, once per
      * each incoming completed bar, and if you don't have 'setComputeOnClose(true)'

      function main() {

        Sorry I can't be more help, but perhaps this thread has some ideas for you.
