  • Problem with BarColor after Restart eSignal

    Hi,

    I have a BarColor-problem, after I restart eSignal. If I insert the indicator in a new chart, all ok, but if I restart eSignal with the saved chart, the Bars "Receiving", but the Bars are not colored correctly. If I reload the indicator, nothing happens.

    PB.efs
    PHP Code:
    function preMain()
    {
        
    setPriceStudy(true);
        
    setStudyTitle("PB");    
    }

    function 
    main()
    {
        var 
    PB;
        
        if (
    cci(20) >= 100PB 1;
        else if ((
    cci(20) < 100) && (cci(20) > -100)) PB 0;
        else 
    PB = -1;
        
        
    //...

        
    return PB;    


    PB_load.efs
    PHP Code:
    function preMain()
    {
        
    setPriceStudy(true);
        
    setStudyTitle("PB_load");    
    }

    var 
    bInit false;
    function 
    main()
    {
        if (
    bInit == false)
        {
            
    PB efs("PB.efs");        
            
            
    bInit true;
        }
        
        if (
    PB.getValue(0) == 1setPriceBarColor(Color.blue);
        else if (
    PB.getValue(0) == 0setPriceBarColor(Color.yellow);
        else 
    setPriceBarColor(Color.red);
        
        return;

    When using setPriceBarColor() you need to include the setColorPriceBars() and setDefaultPriceBarColor() statements in preMain(). See the corresponding links for the required syntax

      Hi Alex,

      with setColorPriceBars(true) in preMain it works great!

      I am only surprised, why it works without the setColorPriceBars-setting, if I inserted the indicator new and after restart eSignal not.

        Hi,

        I have also trouble with the setColorPriceBars. With:

        PHP Code:
        function preMain()
        {
            
        setPriceStudy(true);
            
        setColorPriceBars(true);

            
        fp1 = new FunctionParameter("PB"FunctionParameter.STRING);
            
        with(fp1)
            {
                
        fp1.addOption("T");
                
        fp1.addOption("F");        
                
        setDefault("T");
            }

        }

        function 
        main(PB)
        {
            if (
        PB == "T")
            {
                
        setColorPriceBars(true);
                if (
        close(0) > close(-1)) {setPriceBarColor(Color.blue);}
                else {
        setPriceBarColor(Color.red);}
            }
            else {
        setColorPriceBars(false);}
            

        I get only white candles, if I have PB = F after restart. I know the setDefaultPriceBarColor(), but I dont know the color of each customers for the paintbar...


        Edit: If I use in the else-section (setColorPriceBars(false):

        PHP Code:
                if (close(0) >= open(0)) setPriceBarColor(Color.green,0);
        if (
        close(0) < open(0)) setPriceBarColor(Color.red,0); 
        the color ist not ever correctly realtime like in the original-chart!

          As indicated in the Help files if you use setColorPriceBars(true) you also need to define a default color for the price bars using setDefaultPriceBarColor(Color.xxx)
          In your case what you can do is the following. First declare a global variable called for example bInit and set it initially to false. Then at the beginning of main add the following section of code
          PHP Code:
          if(bInit==false){
                  
          setDefaultPriceBarColor(Color.cyan);
                  
          bInit=true;

          In that section you can replace the color with a user selected color parameter that you will define in preMain with a FunctionParameter.
          Then you can write your section of code as shown below (this includes also the second code sample you added in your message)

          PHP Code:
          if (PB == "T"){
                  if (
          close(0) > close(-1)) {
                      
          setPriceBarColor(Color.blue);
                  }
                  else if (
          close(0) < close(-1)) {
                      
          setPriceBarColor(Color.red);
                  }
              } else {
                  if (
          close(0) > open(0)) {
                      
          setPriceBarColor(Color.green,0);
                  }
                  else if (
          close(0) < open(0)) {
                      
          setPriceBarColor(Color.red,0);
                  }

            is the problem maybe because of the activated "Make all formulas compute on close (rather than tick-by-tick)" under Formula Engine Settings?

              When that setting is enabled the color of the current bar is carried forward from the last bar that has been computed which is bar index -1
