RE: Testnet Server

santhosh.ms said: 

In order to create our own server like FTMO we will need to first understand the basics of server setup and maintenance. We must carefully choose the right hardware and software components that will support our desired functionality. Once we have all the necessary tools and resources we can start building and configuring our server according to our specific requirements. It is important to regularly monitor and update our server to ensure optimal performance and security. By following these steps diligently we can successfully create a server similar to FTMO for our own use.

 

 

Hi there,

Thank you, and if the symbol is mapped correctly, then there is no problem to copy trades  from one broker to another, right?

Hi there,

There is a mapping between symbols with different names. If you think a symbol is not mapped correctly accross symbols, feel free to share more information about it.

Best regards,

Yes this is correct

Which means when my robot execute #USSPX500 in FxPro, for my investor who using ICMarket will execute US500 at the same time when my robot trigger execution but there might be different spread/commission/swap which lead to different PnL result, investor account will execute any order whenever strategy provider account execute any order, is that correct? 

Yes

As explained in your other thread, this is an issue of your cBot, you need to handle this situation inside your cBot code

I saw that other people had the exact same problem, and the same issue happens even if you use an algo bot ctrader generated bot. I don't think it's a “me” problem, there's even a post on quora about someone who had the exact same issue and didn't find any answer here or in the ctrader database. Looks like it's something like a latency issue with ctrader while using bots, if there's a command to input a stop loss and the ctrader doesn't compute that command and proceeds with the order it doesn't look like something an external code should fix.

Hi there,

I have explained why this happens and how it can be handled. If you have evidence that this is not what happens i.e. you set a stop loss outside the spread but it is not placed, then provide us with clear instructions on how to reproduce this and we will have a look.

The thing is, the actual bot is misbehaving, it occurs when the bot is trying to set a stop loss and a sudden movement happens. It happened live just some moments ago.

Hi there,

The stop loss is ignored when it falls within the spread since it is invalid. You need to handle this situation within your cBot code and detect when stop losses are not set due to invalid values.

Best regards,

Panagiotis

And how is it possible to fix this issue? I'm trying to find any article in the support database that makes possible to implement a stop loss verification but can't find one.

Hi there,

You can check if a position has a stop loss using the Position.Opened event. See below an example

using System;
using cAlgo.API;
using cAlgo.API.Collections;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None, AddIndicators = true)]
    public class CheckStopLoss : Robot
    {
        protected override void OnStart()
        {
            Positions.Opened += Positions_Opened;
        }

        private void Positions_Opened(PositionOpenedEventArgs obj)
        {
            if(obj.Position.StopLoss == null)
            {
                // Do something...
            }
        }

        protected override void OnTick()
        {
            // Handle price updates here
        }

        protected override void OnStop()
        {

Hi there,

An obvious problem in your code is that you are using the current open bar's value for your checks. This value can change by the time the bar closes therefore this can lead to false or missing signals. You should only check closed bar values. Try the below instead

           double shortMAValue = shortMA.Result[lastIndex - 1];
           double longMAValue = longMA.Result[lastIndex - 1];
           double prevShortMAValue = shortMA.Result[lastIndex - 2];
           double prevLongMAValue = longMA.Result[lastIndex - 2];

RE: Custom Indicator Values Controlled by cBot in cTrader

cortes.br said: 

I want to plot on the chart points that represent quantities calculated during the execution of the robot, such as limit and stop prices. I need the ability to draw values on the chart for debugging and visualization purposes. Specifically, I am looking for a function equivalent to PlotTimeSeries found in WealthLab.

 

 

PlotTimeSeries

public void PlotTimeSeries(TimeSeries ts, string name, string paneTag, WLColor color = default(WLColor), PlotStyles plotStyle = PlotStyle.Line, bool suppressLabels = false)

Plots a TimeSeries on the chart. The ts parameter is a TimeSeries instance. PlotTimeSeries is useful when plotting the results of mathematical operations on indicators and other TimeSeries. These operations always return instances of the TimeSeries class.

The name parameter should be a descriptive name of the data being plotted. This appears in the pane label.

The paneTag specifies which chart pane to plot the data in. You can specify Price for the price pane, Volume for the volume pane, or some other string value for a custom pane.

The color parameter is optional. If not provided, WealthLab will use a default color.

The plotStyle parameter is also optional, and is a member of the PlotStyle enum. If not specified, WealthLab will use PlotStyle.Line.

The suppressLabels parameter lets you disable to indicator pane labels and the value markers along the chart's right margin for this plot.

Why don't you do all of this in an indicator?

Your problem is this line of code. This is not correct C#

 var line LRs[lr.Name].Children.Add(Chart.DrawTrendLine("Center " + lr.Name, start, pr1, end, pr2, Color.Blue, 1, LineStyle.DotsRare));

Maybe you are trying to do this?

                    var line = Chart.DrawTrendLine("Center " + lr.Name, start, pr1, end, pr2, Color.Blue, 1, LineStyle.DotsRare);
                    line .ExtendToInfinity = true;
                    LRs[lr.Name].Children.Add(line);
