cTrader Team,

Check out this example, where a button is created at startup. Clicking on it should bring up two new buttons.

Problem solved. My cTrader was not up to date, follow the code below with HttpClient replaced by cAlgo.API.Http.
Thanks to "The T"
 

using System;
using cAlgo.API;

        public string TOKEN { get; set; }

        [Parameter("ChatId", DefaultValue = "")]
        public string CHATID { get; set; }


        protected override void Initialize()
        {

        }

        public void SendTelegram(string msg)
        {
            try

                var url = $"https://api.telegram.org/bot{TOKEN}/sendMessage?chat_id={CHATID}&text={msg}";
                var response = Http.Get(url);//httpClient.GetAsync(url).Result;

                if (!response.IsSuccessful)
                {
                    msg += $": Error Sending Telegram Message: {response.StatusCode}, {response.Body}";
                }
                else
                {
                    msg += ": Success";
                }

            }

            Print(msg);

The example in the video does not work as it requires AccessRights.FullAccess.
According to the documentation, the example I shared should work with AccessRights.None, but it gives the error that is in my thread.
I don't know if I'm missing something because I've tried several methods without success to make it work with AccessRights.None

Check event signature before using it: SelectedItemChanged Event - cTrader Automate API

Hi amusleh,

I was testing the indicator I am developing and came across a ctrader bug.

For example, with the code you provided, select "Item 2", change chart tab and go back to the tab where you have the indicator. It should keep "Item 2" selected. I have tried to solve it via code, but the logs return "Item 2" selected, I believe it is a visual bug. Can you test it there please?

Thanks in advance

The question was whether it is possible. Not if it was functional.
Functional is relative, if it is for example to "clone" the trades, no. If it is for report documents or notify followers on telegram, yes.

Hello my Friend,

First of all, I hope your career path is being a success....

Thanks for your reply, in the meantime I have resolved and thought the opposite, if I want to do merging, why not start with 1 column and add what I want like "unmerge"? Solved it :)

Thanks!!

Here is an example in case someone in the future needs it.

using System;

            {
                Width = 100,

Thank you so much my friend!! Thank you

For those who are interested, the solution:

Change the line:

private void myDropList_SelectedIndexChanged(object sender, ComboBoxSelectedItemChangedEventArgs e)

to:

private void indicatorsDropList_SelectedIndexChanged(ComboBoxSelectedItemChangedEventArgs obj)

Thank you very much for your reply!

The robot has almost 8 thousand lines with arrays and connections to databases, I created a basic one to facilitate you and the situation is the same.

Start cBot a stop. Close manually opened trades to be part of the history, after that starts cBot again and confirms that the 'HistoricalProfitInCash' in the 'Chart.DrawStaticText' will significantly change tick by tick and meaningless.

Please check. I am grateful to you!!
