Lag issues when running cBots on cTrader

Ηι wefald,

Thank you for posting in our forum.

About the notice that he bots give, since i have been informed there is no way to make the bots create pop-ups ala cTrader's price alerts (which would be a feature I would really like to have),

Who told you this? Of course you can create pop ups using cBots. e.g.

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
using System.Windows.Forms;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]
    public class NewcBot : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        protected override void OnStart()
        {
            MessageBox.Show("test", "test");
        }

        protected override void OnTick()
        {

        }

        protected override void OnStop()
        {

        }
    }
}

With the way you have chosen to handle this, I would expect bottlenecks. Try converting your cBot to use pop ups or email alerts and let us know if the performance is improved.

Best Regards,

Panagiotis

Thanks for replying fast.

I don't have a name regarding who told me this, but someone did. Either from the FxPro support team or from Spotware, as I was learning how to program cBots.

(Since I was told I could not make a pop-up window at all, I think my solution is rather creative. But yeah, bottlenecking during busy times when trying to send a bunch of orders shouldn't come as a big surprise to anyone.)

I tried the code you just provided, but I got an error saying that the type or namespace name Forms does not exist in namespace System.Windows (Maybe you miss a "samlingsreferanse"?)

(The error message was in Norwegian, but the last word translates word for word to collection referance)

Hi wefaid,

You need to add a reference to System.Windows.Forms. See below

Best Regards,

Where is this panel found? I can't see it anywhere.

It worked. Thanks!

Is it also possible to make this pop-up make a sound of some kind? The "pop" sound of a rejected buy order is a big part of why I chose that solution.

A search for "messagebox" in the cBot API I have yielded zero results.

If sound is not doable, then do you have similar code for an email alert? I could have an alert sent to some account that i equipped with desktop notifications.

Hi wefaid,

You can use Notifications class for both sound and email alerts.

Best Regards,

Dear Panagiotis,

I also have this issue even though I have switched to onBar. Please explain in details what bottlenecks to expect so that I can manage it. 

Thanks in advance.
