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. I have the setup for max 15 pips of stop loss on this strategy. When buying there was a massive movement to go down. Stop loss wasn't setted and now I'm in a huge loss. This is severe, please fix. 

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.

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()
        {
            // Handle cBot stop here
        }
    }
}

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

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);

First of all, thank you for your attention. I have already submitted the form with a link to this forum.

The idea is that the cBot will determine and set the indicator values during each OnBar event, and these values will then be plotted on the chart by the indicator.

Can you please explain to us why this design is necessary?

Hi there,

The result of the method is units, which is what you need as an input for all the order methods of the API. There is no reason to convert it to lots and then back to units. But if you need to convert it to Lots, you can use the Symbol.VolumeToQuantity() method.
