You can invoke the Chart.RemoveAllObjects() to have everything deleted in one shot.

I would limit the number of objects drawn on the chart during backtesting.

Hi @sigure,

in my experience the NaN is returned when it's not possible to calculate a certain indicator and there are 2 reasons behind:

1. Data does not exist, for example you ask cTrader to calculate a MovingAverage over 200 period of a Monthly timeframe for BitCoin, and you get the NaN response (which makes sense)
2. Historical Data has not been loaded, there is in cTrader  a function named Bars.LoadMoreHistory() that is supposed to help but … in my experience that never worked. What really worked for me is change the broker and access to a serverwhere your data is present. For example when I get the NaN response, i switch from ICMartes account to cTrader Demo account and everything works 

I hope that helps.

Ciao, Claudio

Well, if it's 22:01 UTC I think it's because of the crazy midnight spread.

Forex USDSGD that you are trading is not regulated and spread is getting creazy at that time.

Ciao, Claudio

I use Telegram.Bot from RoundRobin

Version 18, not version 23 that is giving me problems and it works well.

using Telegram.Bot;
 

       internal static async void SendTelegram(string chatId, string token, string telegramMessage, CtraderEnvironment.CtraderEnvironment ctraderEnvironment)
       {
           // N.B. Use Telegram.Bot RounfRobin version 18
           // Do not use latest version 23 because it's not working

           if (chatId == "")
               return;
           if (token == "")
               return;
           if (telegramMessage == "")
               return;

           string reply = string.Empty;

           try
           {
               var telegramBot = new TelegramBotClient(token);
 

               await telegramBot.SendTextMessageAsync(chatId, telegramMessage);

               reply = "SUCCESS";
           }
           catch (Exception exception)
           {
               reply = "ERROR in SendTelegram: " + exception.Message;
               ctraderEnvironment.Log.LogError(reply);
           }
       }

If you find a way to have the leatest version 23 working please tell me ))

Assuming that a volume of 0.02 is above the min volume for the symbol that you are trading → you can check this with Symbol.VolumeInUnitsMin

You can only manage a double take profit programmatically.

You have to do something like this:

        protected override void OnTick()
       {
           double myTakeProfit1 = 100;
           foreach (Position position in Positions)
           {
               if (position.Pips >= myTakeProfit1)
               {
                   if (position.VolumeInUnits > 0.02)
                       position.ModifyVolume(0.02);
               }
           }
 

With position.ModifyVolume you close the first part of the position that reached your TP,

and then check for the second take profit condition at a later stage.

Having the volume coded into your logic is not elegant even if it's working,

you you want to something better then you need to create a list of positions that you manage.

I hope this helps.

Hi Claudio,

This issue should have been fixed in v5.0.29. Please use the latest version instead.

Best regards,

Panagiotis

Hi Panagiotis,

I can confirm that v.5.0.29 solved both the 2 issues:

• Positions ID are not mismatched
• NetProfit is correctly returned and fully matching the values in the history tab

Thanks a lot, ciao!
