RE: Grids not showing

Panagiotis,

Another thing that i observe is that when placing two or more indicators on the same area

the indicators are rescaled individually regardless of the AutoRescale property.

This can be clearly seen scrolling back.

Hi Takis,

Can you please record a video demonstrating the steps that lead to this behavior?

Best regards,

Panagiotis

Hi Panagiotis,

Here is some minimum code extracted from my indicators to help reproduce the issue.

Adding the indicator in a NewPanel, Grid does not show.

Saving and reloading the workspace, it will show.

Move it on Chart, then back to NewPanel and it's hidden again.

I was expecting that with given code the Result output would work correctly even with IsOverlay = false

And indi placed on Chart but this does not happen. My expectation was based on the assumption that after the 

addition of Chart/NewPanel the IsOverlay would become obsolete. Anyway, this case is not very important.

Dear traders,

Thanks for reporting this problem. 4.6.2 hotfix has been released. Please let us know if you still experience issues in 4.6.2.

Best regards,

4.6.2 gave me a headache.

Everything was going wrong until I discovered that ver (1.*) or (1.0.5) dependency was stucked in my projects and for some reason we're not automatically updating.

Manually updating those nuget packages all is smooth like it was supposed to be.

Very minor errors still exist but the developers team will fix them.

Source code not available

Hi,

I had the same problem.

It appears that older versions of visual studio leave attributes in the csproj file

that cause this behavior. I had to manually clean all csproj files.

Remove lines like

    <EnableDefaultItems>False</EnableDefaultItems>
    <GenerateAssemblyInfo>False</GenerateAssemblyInfo>

Hi Takis,

This is caused due to a lazy loading design of the IndicatorDataSeries. Calculate function is only called when Last() method and LastValue property are called for an output IndicatorDataSeries. This was always the case.

You can use workaround like:

{
    if(PrevIndex!=index)
    {
        // do your barstuff here;
        PrevIndex=index;

Hi Takis,

You legend! I had tried so many OnTimer options and none of them seemed to register the re-connections. Your version works beautifully!

For anybody else reading this thread I have completed the code to have the Thread.Sleep included. The reason for this script is upon reconnecting, the server at times sends a false Bid/Ask price and my bot likes to trade on it - creating a label which is well out of the array my bot runs. This delay allows ctrader to fully catch-up and have accurate Bid/Ask prices.

 

Now I just need to solve my BollingerBand issue.

        Color clrMinus = Color.Gray;

        protected override void OnStart()
        {
            // Put your initialization logic here
            Server.Connected += OnServerConnected;
            Server.Disconnected += OnServerDisconnected;
            PlusMinusColors(Server.IsConnected);
        }

        void OnServerConnected()
        {
            PlusMinusColors(true);
        }


        void OnServerDisconnected()
        {
            PlusMinusColors(false);
        }

        void PlusMinusColors(bool plus)
        {
            if (plus)
            {
                clrPlus = Color.Lime;
                clrMinus = Color.Tomato;
                Print("Connected, pausing trades for 15 seconds.");
                System.Threading.Thread.Sleep(15000);
                Print("Trading active again.");
            }
            else
            {
                clrPlus = Color.Gray;
                clrMinus = Color.Gray;
                Print("Disconnected");
            }

In automate, run a robot.

Double click on the file name and change it.

The instance is removed.

In code, the class name is changing so you have to save.

Now the compile button is red and grayed.

You can add an instance, start it, stop it, remove it,
