How to get the value of something manually drawn on the chart? ?

AndersonLuiz

Hi guys, I'm trying to code a simple bot that scans the chart and get the prices of all horizontal lines already present on the chart (drawn by hand before starting the bot).
Can someone help me? I have no idea how to get the value of something that was manually drawn on the chart.

I know you can get a drawing object via code if you know the name.

// Draw a horizontal line.
Chart.DrawHorizontalLine("hLine", Symbol.Ask, Color.Red);

// Find the line that was drawn.
var obj = Chart.FindObject("hLine");
Print("Found object with name {0}", obj.Name);

Not sure how you would do this if you draw it manually, why not contact ClickAlgo's coding team for help?

Thank you Sebastian, using your code as an example, I managed to find a solution.
I'm going to improve the code later, but here it is:

    private ChartObject[] myChartObjects;
    private ChartHorizontalLine[] myHorizontalLines;

    protected override void OnStart()
    {
        myChartObjects = Chart.FindAllObjects(ChartObjectType.HorizontalLine);
        myHorizontalLines = new ChartHorizontalLine[myChartObjects.Length];
        Print("Number of horizontal lines on the chart {0}", myHorizontalLines.Length);

        for (int i = 0; i < myChartObjects.Length; i++)
        {
            myHorizontalLines[i] = myChartObjects[i] as ChartHorizontalLine;
            Print(myHorizontalLines[i].Y);
        }
    }

Yes, that should work, thanks for sharing.
