Yes, especially when the customised indicator has many parameters.

I look forward to seeing the function to be implemented. Especially, when the customised indicator has many parameters.

Anyone like this idea please vote

RE: RE: RE:

Oh, yes, I tried locking the object, but the highlight is still there when hovering over it. Anyway, it's a tiny issue here.   

Thanks for the reply again. :)

Oh, thanks.  I just realised.

Generally, if the object in chart is IsInteractive = True, is there any way to get rid of the highlight when the mouse hovers over? Maybe not, I guess...

 

amusleh said:

Hi,

To show the time on x axis you have to set the line IsInteractive property to true.

 

Hi,

You can try setting the IsLocked property of object to True, this will lock the object and user will not be able to update the object unless it's unlocked.

RE:

Thank me, the problem has been resolved. 

There are some bars gaps between the data series to the bars' index number. Get the gap value e.g gap_EURUDS and put them in the right place as below would fix the problem.

...
        {
            USD[index] = 200*(  (1/EURUSD[index + gap_EURUDS].Close)
                               *(1/GBPUSD[index + gap_GBPUSD].Close)
                               *(1/AUDUSD[index + gap_AUDUSD].Close)
                               *(1/USDCAD[index + gap_USDCAD].Close)
                               *(1/NZDUSD[index + gap_NZDUSD].Close)
                               *  (USDCHF[index + gap_USDCHF].Close)
                               *  (USDJPY[index + gap_USDJPY].Close)

Hi,

You can use a bool flag to avoid the second call:

using cAlgo.API.Internals;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]

        private ChartHorizontalLine hlStopLoss;

        private bool _updatingComment;

        protected override void OnStart()
        {
            hlStopLoss = Chart.DrawHorizontalLine("StopLoss", Symbol.Bid, Color.FromHex("#BBFF7777"), 1, LineStyle.LinesDots);
            hlStopLoss.IsInteractive = true; hlStopLoss.IsLocked = false; hlStopLoss.Comment = Symbol.Bid.ToString();
            Chart.ObjectsUpdated += SLModified;
        }

        protected override void OnTick()
        { }

        protected override void OnStop()
        { Chart.RemoveObject(hlStopLoss.Name); }

        private void SLModified(ChartObjectsUpdatedEventArgs obj) //Modify HorizentialLine, to update Price in Comments
        {
            if (_updatingComment)
            {
                _updatingComment = false;

                return;
            }

            var horizentalLine = obj.ChartObjects.FirstOrDefault(iObject => iObject.ObjectType == ChartObjectType.HorizontalLine && iObject.Name.Equals(hlStopLoss.Name, StringComparison.OrdinalIgnoreCase));

            if (horizentalLine != null)

            var icon = Chart.DrawIcon(sMessage, ChartIconType.UpArrow, Bars.LastBar.OpenTime, Bars.LastBar.Low * 0.999, Color.FromHex("#DDE7E7E7"));

I should define the icon first. So that we can set the properties for it.  

Much appreciated.

You can set the object IsInteractive flag to True:

using cAlgo.API;

            var icon = Chart.DrawIcon(sMessage, ChartIconType.UpArrow, Bars.LastBar.OpenTime, Bars.LastBar.Low * 0.999, Color.FromHex("#DDE7E7E7"));

            icon.IsInteractive = true;

        }

        protected override void OnTick() {}

        protected override void OnStop() {}

}

The IsLocked is an additional optional step which disables moving of object, but you can turn it on/off from object settings.

Thank you Amusleh,  I believe this is the right way to process the code. 

Well, in my practice, the following question is,  there are multiple TextBlocks in a Grid or several Grids,  and they all need to change ForegroundColors and Positions by the price up or down. Is there any quick way, I can change all the TextBlocks' ForegroundColor and other properties rather than one by one which makes the code extremely long?

Thanks again in advance.

amusleh said:

Hi,

I will answer each of your point:

1. Yes, it will, you should not create a new button or canvas on each tick/bar

2. It will, because any control you create will live on memory as long as you remove it from chart or remove your indicator from chart

3. You should use OnInitilaize method and only change the control properties based on your criteria.

Here is your indicator code that is properly written:

using cAlgo.API;

namespace cAlgo
{
   ...
}

 

 

Hi,

You can put all the controls inside a collection like list and then change them one by one or use a parent custom control.

There is no other way except updating each control on a sequential order.

But it will continue sending emails when the single triggered in the last bar running. However, I've managed to add 2 bools to control the email sending, which make it what it originally planned to do.
