Need help with code almost done.

Description

can somebody please fix my code is just a simple code with some errors. Thanks

Description : An indicator that automatically positions a horizontal line within a drawn rectangle on the chart, placing it precisely at the center of the rectangle.

using cAlgo.API;

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AutoRescale = false, AccessRights = AccessRights.None)]
    public class RectangleHorizontalLine : Indicator
    {
        private HorizontalLine horizontalLine;
        private ChartRectangle rectangle;

        protected override void Initialize()
        {
            rectangle = Chart.DrawRectangle("rectangle", Symbol.Bid - Symbol.Pip, MarketSeries.OpenTime.Last(1), Symbol.Bid + Symbol.Pip, MarketSeries.OpenTime.LastValue, Color.Blue);
            rectangle.IsFilled = false;
            rectangle.IsInteractive = true;

            horizontalLine = Indicators.HorizontalLine((rectangle.Y + rectangle.Height) / 2);
            horizontalLine.IsInteractive = false;
            horizontalLine.IsLocked = true;
            horizontalLine.IsVisible = true;
        }

        public override void Calculate(int index)
        {
            // No calculation is needed for this indicator
        }
    }
}

The FVG indicator you're inquiring about is just one element of your trading strategy. There are numerous variations in trading strategies, each influenced by the unique properties of financial instruments. The initial step involves identifying price movements characterized by FVG attributes, encompassing both positive and negative price sentiment.
Here is a FVG indicator to identify FVG sentiment, maybe is useful for your project.

there are a few fair value gap examples on here (tho none that i have immediate links to). I'm sure you know how to identify those in code. from there, it's just a matter of using the ‘gap’ that been discovered to fill the rectangle area and doing some tick maths to determine the centre line (discount area).

I have created my own version of this that also incorporates the ldn/ny killzones as shaded areas. however, it's not a project that is easily shared as it uses a few 3rd party components also. However, what I am saying is that by breaking this problem down into bite sized chunks, you'll be able to create the indicator you're after. I'll see what bits of code i do have that would help with the FVG identification tho.. and drop here if it'seasily extracted from my codebase.

First of all thanks for your help sir

The code you've provided is impeccable and functions seamlessly, yet it doesn't precisely match my requirements.

Would you mind creating an indicator for me? I'm looking for something tailored to the Inner Circle Trader method called +IFVG. This indicator should let me draw rectangles on any timeframe and resize them as necessary. Also, it should automatically fill the rectangle with a corresponding line. Your assistance with this would be much appreciated!

Similar to the functionality provided by the tradingview platform with the rectangle tool, I'm seeking an indicator that offers similar features.
