Dont know what the problem was as the above did not solve it. But i reinstalled windows 10 and it fixed the issue.. Thanks. It must have been some kind of file write permission problem or something.

Hi Panagiotis, Ohh ok... that food for thought!

Thanks for that i will investigate that with you guys or my broker closer to when im ready.

Hi Panagiotis, Thank you for that...

I think you guys should really do this as it will give a whole new marketplace access to ctrader.. there is not many other software platforms based on C# as well and the ones that are, are not connected to great brokers anyway...

Next time you guys discuss this please make a plan to really do it..

Its also something i am working towards as well (Like Seriously around 6-12 months time)

But i am happy for the moment with the current setup.

Hi Panagiotis Charalampous is trhere any chance that you guy can addd UI automation to the API so we can control cTrader UI elements and charts from code? this is something im verty interested in as well. Thank you

Unfortunately you cannot tell for which Symbol was the OnTick() called.

Hi Panagiotis

thank you for the last reply

Ok so i was trying to make some kind of work around property that invoke my own tick method on change but cAlgo wont build and gives me an error:

Unable to load assembly: "EurUsd" parameter must be an auto-property

Wht is the situation with preset properties and calgo?

Multi-symbol robots and indicators - Which Symbol Invoked OnTick?????

Hi Panagiotis or anyone else who knows

on testing this code above the cAlgo Symbol Interface only returns symbol data for the symbol that is selected with calgo to run the robot with but will invoke on ticks from the four symbols entered in the OnStart method.

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
 
namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }
 
        protected override void OnStart()
        {
            var EURUSD = MarketData.GetSymbol("EURUSD");
            var GBPUSD = MarketData.GetSymbol("GBPUSD");
            var EURJPY = MarketData.GetSymbol("EURJPY");
            var USDJPY = MarketData.GetSymbol("USDJPY");
        }
 
        protected override void OnTick()
        {
            Print("Symbol -" + Symbol.Code + " |  Bid = " + Symbol.Bid );
        }
 
        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

How do i tell OnTick Method or Symbol Interface which Symbol Invoked it?

I think i will use Named Pipes as there are much more examples and tutorials around to help me set up WCF than i have found for MMF. i also think it will be better for what i am doing as i want each instance to send mesaages to the master when anything significant happens on ticks coming in Asynchronously and also the master to send messages to the slaves. WCF looks like it will handle message queuing and other underlying stuff so i think thats the best direction for me to take. if i get into any problems with this in calgo i will ask your advice again. Thank you very much Panagiotis

Panagiotis Charalampous said:

Hi GammaQuant,

Thanks for the links. There is a mention in one of them that you could use static collections to share variables between cBots but this is not possible. I assume that the person that suggested this never actually tried it. The reason that this cannot happen is that you cannot compile more than two cBots in the same dll. As a result, each cBot exists in a different dll and they cannot share variables between them. If you need to share information between cBots maybe you can consider reading and writing to a file accessible by both. Let me know if this suggestion helps.

Best Regards,

Panagiotis

Hi Panagiotis Ok so this is not possible then for sure.....

I am building a high performance trading system that will be running over 10 to 30 instances with a master instance controlling the other intances. As this is quite a complex system i dont want the performance to suffer so after lots of research on the available options i could take i have thought about doing this with WCF Named Pipe Binding with Protobuf serialization or doing it with Memory Mapped Files. i have never dont this before having only started programming c# 4 months ago so any advice would be appreciated.

Thank you.

[Parameter("Start Hour", DefaultValue = 6.0)]
public double StartTime { get; set; }
 
[Parameter("Stop Hour", DefaultValue = 18.0)]
public double StopTime { get; set; }


private bool _todaysOrderExecuted;



protected override void OnBar()
{
    var currentHours = Server.Time.TimeOfDay.TotalHours;
    bool tradeTime = StartTime < StopTime
                ? currentHours > StartTime && currentHours < StopTime
                : currentHours < StopTime || currentHours > StartTime;

    if (tradeTime && !_todaysOrderExecuted)

}

private void ExecuteStrategy()
{
*** Execute strategy code****
    if (result.IsSuccessful)
    {
        _todaysOrderExecuted = true;
    }
}

this will allow you to only trade between certain times of the day and will only open one trade per day. it will use the servertime in calgo. dont use Datetime as that is the time in your computer and not the brokers Server time.

For a start the are two OnStart Methods. obviously it wont work with two.

this function :

protected override void OnBar()
        {
            ExecuteMarketOrder(TradeType.Buy, Symbol, Volume, "BUY");
            ExecuteMarketOrder(TradeType.Sell, Symbol, Volume, "SELL");
            foreach (var position in Positions)
            {
 
                if (position.Pips > 4.3)
                (
                    ClosePosition(position)

should be

protected override void OnBar()
        {
            ExecuteMarketOrder(TradeType.Buy, Symbol, Volume, "BUY");
            ExecuteMarketOrder(TradeType.Sell, Symbol, Volume, "SELL");
            foreach (var position in Positions)
            {

                if (position.Pips > 4.3)
                {
                    ClosePosition(position);
                }
            }
        }

I dont understand what you are trying to achive with the rest of it....

Thank you very much for that Wow that obvious isn't it...... :). Sorry ive only be programing c# for 1.5 months. but i exspanded on your solution so that i only have to pass it once in the onstart and then i use a static method every where i invoke calgo api methods out side of the main class and any methods within the main class from any other of the classes that ive created for my framework.
