Dear Trader,

Thanks for posting in our forum. This is currently not possible in cAlgo. A workaround is to get the Color as a string parameter and use the following function to convert the string to a Color

        //A function for getting the color from a string
        private Colors GetColor(string colorString)
        {
            foreach (Colors color in Enum.GetValues(typeof(Colors)))
            {
                if (color.ToString() == colorString)
                    return color;
            }
            return Colors.White;
        }

Let me know if this helps,

Best Regards,

Workaround

Is there another workaround, by retreiving the color from an IndicatorDataSeries ? In that case one could define a dataseries and use the settings for making lines.

Hi ADFX,

It is not possible to retrieve the color of IndicatorDataSeries using cAlgo.

Simple method:

        private Colors GetColor(string colorText, string colorParameterName)
        {
            Colors color;

            if (!Enum.TryParse(colorText, true, out color))
            {
                string errorObjName = string.Format("Your input for '{0}' parameter is incorrect", colorParameterName);

                ChartObjects.DrawText("Error", errorObjName, StaticPosition.Center, Colors.Red);

                // throw new ArgumentException(errorObjName);
            }

            return color;
        }
