I am havign the same problem. RoboForex has disabled all trading for the last 2 days. I tried contacting them and here is what they said:
"We have received the latest info that this situation is temporary and is connected to the execution on the side of the liquidity providers. Now we are looking further into it and checking the details. Now trading there is in "close only" mode."
Then they said:
"The сTrader platform is indeed currently operating in the Close only mode. It is not a restriction placed specifically on your account. There is currently no information in regards to the resumption date, but you are welcome to try our MetaTrader and rTrader platforms in the meanwhile."
Can we have a deeper explaination why the broker would do this because this relects badly on cTrader? They are essentially tanking your platform and sending customers over to your competitors.

This will be great however, let me mention that even if it worked as you suggested, We would still be missing the YValue of the Hover Object. With the Mouse move I can ge tthe YValue but no ChartObject is returned only the whole list of ChartObjects. I could iterate through the chart objects and find one with the same Time value and ChartObject type to trigger a Drawtext but this could be inefficient and expensive. There is no way to limit the objects returned by the mousemove event, so you have to iterate through all objects from the begining of the chart.
So, for the OnChartHover Changed to be complete all you need to do is add the non-interactive chart objects and return the Yvalue of where you hovered over.

I see what you have done. It looked promising but i can't get it to work. It looks like this is a Robot not an indicator. I copied it exactly as above but it does not print the index and does not show the line. Are you sure this works?
I tried revising it like below but still no luck.
using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
namespace cAlgo
{
[Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
public class NewIndicator : Indicator
{
[Parameter(DefaultValue = 0.0)]
public double Parameter { get; set; }
protected override void Initialize()
{
Chart.ObjectHoverChanged += OnChartObjectHoverChanged;
}
public override void Calculate(int index)
{
if(MarketSeries.OpenTime[index].Hour == 8 && MarketSeries.OpenTime[index]>Convert.ToDateTime("2/1/2019"))
{
var divLine = Chart.DrawVerticalLine("Dayend" + index, index, Color.Orange, 1, LineStyle.DotsRare);
divLine.Comment="This is news: " + index;
//AllVerticelLines.Add(new VerticalLine(divLine.Name, index, divLine.Time,divLine.Comment));
}
}
void OnChartObjectHoverChanged(ChartObjectHoverChangedEventArgs obj)
{
if (obj.IsObjectHovered)
{
if (Chart != null)
Chart.DrawStaticText("hoverText", obj.ChartObject.Name, VerticalAlignment.Top, HorizontalAlignment.Left, Chart.ColorSettings.ForegroundColor);
if (obj.ChartObject is ChartVerticalLine)
Print("Index " + (obj.ChartObject as ChartVerticalLine).Time);
}
else
Chart.RemoveObject("hoverText");
}
}
}

Ok! Well, I figured it out! It may not be optimal, if there is a way to get the VerticalLine index returned to the MouseMove event. But since I could not figure out how to get that information I crated my own list with the data for the ojects. Here is the code.
using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;
using System.Collections.Generic;
using System.Linq;
namespace cAlgo
{
[Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
public class NewIndicator : Indicator
{
[Parameter(DefaultValue = 0.0)]
public double Parameter { get; set; }
[Output("Main")]
public IndicatorDataSeries Result { get; set; }
public class VerticalLine : ChartVerticalLine
{
public DateTime Time{ get; set;}
public int Thickness{ get; set; }
public LineStyle LineStyle{ get; set; }
public Color Color{ get; set; }
public string Name { get; set; }
public string Comment { get; set; }
public bool IsInteractive { get; set; }
public bool IsAlive { get; set; }
public ChartObjectType ObjectType { get; set; }
public int ZIndex { get; set; }
public int Index { get; set;}
public VerticalLine (string _name, int _index, DateTime _datetime, string _comment)
{
Name=_name;
Index=_index;
Time=_datetime;
Comment=_comment;
}
}
List<VerticalLine> AllVerticelLines;
protected override void Initialize()
{
AllVerticelLines = new List<VerticalLine>();
Chart.MouseMove += Chart_MouseMove;
Chart.ObjectHoverChanged += OnChartObjectHoverChanged;
Chart.MouseDown += Chart_MouseDown;
Chart.MouseUp += Chart_MouseUp;
}
public override void Calculate(int index)
{
//Just creates some sample Verticle lines for testing
if(MarketSeries.OpenTime[index].Hour == 8 && MarketSeries.OpenTime[index]>Convert.ToDateTime("2/1/2019"))
{
var divLine = Chart.DrawVerticalLine("Dayend" + index, index, Color.Orange, 1, LineStyle.DotsRare);
divLine.Comment="This is news: " + index;
AllVerticelLines.Add(new VerticalLine(divLine.Name, index, divLine.Time,divLine.Comment));
}
}
private void Chart_MouseMove(ChartMouseEventArgs obj)
{
List<VerticalLine> OnScreenVerticleLines = AllVerticelLines.Where(x=> x.Index>=obj.Chart.FirstVisibleBarIndex && x.Index<=obj.Chart.LastVisibleBarIndex).ToList();
for (var i = 0; i < OnScreenVerticleLines.Count; i++)
{
if(obj.TimeValue==OnScreenVerticleLines[i].Time)
{
var newsText = Chart.DrawText("NewsText", AllVerticelLines[i].Comment, obj.TimeValue, obj.YValue, Color.White);
newsText.VerticalAlignment = VerticalAlignment.Center;
newsText.HorizontalAlignment = HorizontalAlignment.Center;
}
}
//*** For testing purposes ***
//Print("Alllines:{0} Onscreen:{1}",OnScreenVerticleLines.Count,AllVerticelLines.Count);
//Chart.RemoveObject("hoverText");
//Print(MarketSeries.OpenTime[obj.Chart.FirstVisibleBarIndex].ToString("MM/dd/yyyy HH:mm"));
//Print(MarketSeries.OpenTime[obj.Chart.LastVisibleBarIndex].ToString("MM/dd/yyyy HH:mm"));
//Print(obj.Chart.LastVisibleBarIndex);
//Print("objects:"+obj.Chart.Objects.Count);
//Print("Name:{0} Type:{1} Z:{2} InterAct:{3}", obj.ChartArea.Objects[0].Name, obj.ChartArea.Objects[0].ObjectType, Chart.Objects[0].ZIndex, Chart.Objects[0].IsInteractive);
//Print("Barindex:{0} Timevalue:{1} YValue:{2}",obj.BarIndex,obj.TimeValue,obj.YValue);
//foreach (object _object in obj.Chart.Objects)
// Print("obj:"+_object.ToString());
}
private void Chart_MouseDown(ChartMouseEventArgs obj)
{
Chart.RemoveObject("NewsText");
}
//*** Not Used here but left here as an example
void OnChartObjectHoverChanged(ChartObjectHoverChangedEventArgs obj)
{
if (obj.IsObjectHovered)
{
Chart.DrawStaticText("NewsText", obj.ChartObject.Name, VerticalAlignment.Bottom, HorizontalAlignment.Left, Color.White);
}
else
{
Chart.RemoveObject("NewsText");
}
}
private void Chart_MouseUp(ChartMouseEventArgs obj)
{
}
}
}

Well, the DrawVerticleLine allows the user to move the line, so this is not the behavior I want.
Bottom line is that I can find no way to get the indexbar, time or y-value of the chartobjects. I can get the char object name and the list of objects but not the other properties.

Ok, so i got the ObjectHoverChanged to fire. you have to set the interactive property, like so...
var divLine = Chart.DrawVerticalLine("Dayend" + index, index, Color.Orange, 1, LineStyle.DotsRare);
divLine.IsInteractive=true;
So, now the question remains, whether the On mouseMove can get the coordinates of an object that is not interactive?

Well, I figured out why the onHover is not working: DrawVerticalLine is not interactive. So which objects are?
Isinteractive: Defines whether the instance is interactive. The non-interactive chart objects cannot be selected, have no hover effect and cannot be searched. Available only to the current cBot or Indicator and will be removed when the cBot/Indicator stops TBD

I have been trying all kinds of stuff without any success.
The OnChartObjectHoverChanged won't fire at all. i used the mouse move to test but there does not seem to be a way to get the time value from the chart object in order to compare it to the mouseMoveEventArgs.
private void Chart_MouseMove(ChartMouseEventArgs obj)
{
Print("objects:"+obj.Chart.Objects.Count);
Print("name:{0} Type:{1} Z:{2}", obj.ChartArea.Objects[0].Name, obj.ChartArea.Objects[0].ObjectType, Chart.Objects[0].ZIndex);
obj.ChartArea.
Print("Barindex:{0} Timevalue:{1} YValue:{2}",obj.BarIndex,obj.TimeValue,obj.YValue);
foreach (object _object in obj.Chart.Objects)
Print("obj:"+_object.ToString());
}

oK, I created a sample indicator but i can't get it to do anything. Not even print hello.
using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;
namespace cAlgo
{
[Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
public class NewIndicator : Indicator
{
[Parameter(DefaultValue = 0.0)]
public double Parameter { get; set; }
[Output("Main")]
public IndicatorDataSeries Result { get; set; }
protected override void Initialize()
{
Chart.MouseMove += Chart_MouseMove;
Chart.ObjectHoverChanged += OnChartObjectHoverChanged;
}
public override void Calculate(int index)
{
var divLine = Chart.DrawVerticalLine("Dayend" + index, index, Color.Orange, 1, LineStyle.DotsRare);
Print(divLine.Time);
}
private void Chart_MouseMove(ChartMouseEventArgs obj)
{
}
void OnChartObjectHoverChanged(ChartObjectHoverChangedEventArgs obj)
{
if (obj.IsObjectHovered)
{
if(Chart!=null)Chart.DrawStaticText("hoverText", obj.ChartObject.Name, VerticalAlignment.Top, HorizontalAlignment.Left, Chart.ColorSettings.ForegroundColor);
}
else
Chart.RemoveObject("hoverText");
}
}
}

How would I test for the TimeValue of a previously drawn vertical line? if I asign a drawverticle line to a variable like this
var divLine = Chart.DrawVerticalLine("Dayend" + index, index, Color.Orange, 1, LineStyle.DotsRare);
I get an error:
Error CS1023: Embedded statement cannot be a declaration or labeled statement

You should check out the cBot I posted here: https://ctrader.com/algos/cbots/show/1849
You have to pass the cBot object to the form:
counter = new frmCandleCountdown(this, paramOnTop);
the "this" key word is the object.
So, you have to modify the default windows method something like this:
public frmCandleCountdown(myCandleCountDown _caller, bool _alwaysOnTop)
{
alwaysOnTop = _alwaysOnTop;
caller = _caller;
InitializeComponent();
}
You also have to declare your cBot obkect in the windows form like this:
myCandleCountDown caller;
Then create a function in your cBot to execute a trade.
Then call the function OnClick

Well, is there a way to test if the position exists before closing it?
