OutputAttribute "LineColor" change issue

Hi all,

I have a very strange problem, in the following code I intercept the value of the LineColor:

...



        private T GetAttributeFrom<T>(string propertyName)
        {
            var attrType = typeof(T);
            var property = this.GetType().GetProperty(propertyName);
            return (T)property.GetCustomAttributes(attrType, false).GetValue(0);
        }

        private void DrawBestandWorst()
        {


            if (_canDraw())
            {

                if (bestCurrency.LastValue != 0)
                {
                    
                    var myOutputBest = this.GetAttributeFrom<OutputAttribute>(bestCurrency.Currency);
                    ChartText myTextBest = IndicatorArea.DrawText("BestCurrency", "BEST » " + bestCurrency.Currency + " » " + bestCurrency.LastValue.ToString("N2"), Bars.OpenTimes.LastValue, bestCurrency.LastValue, Color.FromName(myOutputBest.LineColor));
                    myTextBest.IsInteractive = false;
                    myTextBest.FontSize = 12;
                    myTextBest.VerticalAlignment = VerticalAlignment.Center;
                    
                }

                if (worstCurrency.LastValue != 0)
                {

                    var myOutputWorst = this.GetAttributeFrom<OutputAttribute>(worstCurrency.Currency);
                    ChartText myTextWorst = IndicatorArea.DrawText("WorstCurrency", "WORST » " + worstCurrency.Currency + " » " + worstCurrency.LastValue.ToString("N2"), Bars.OpenTimes.LastValue, worstCurrency.LastValue, Color.FromName(myOutputWorst.LineColor));
                    myTextWorst.IsInteractive = false;
                    myTextWorst.FontSize = 12;
                    myTextWorst.VerticalAlignment = VerticalAlignment.Center;

                }
            }

        }


...

It works fine, but if I change the color in the indicator parameters this does not change, the LineColor value is not updated
