cAlgo.API is not thread safe. Please avoid accessing API objects and methods from separate threads. If exception happens, the entire application will crash.

Not a big help for the moment ... like "Doctor, when I touch here I feel pain ... so don't touch here!"

Do you use cAlgo OnTimer method or system timer?

Here you are the code:

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;
using System.Globalization;

    public class testClipboard : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }


        protected override void OnStart()
        {


            Timer.Start(TimeSpan.FromMilliseconds(1));
            //start timer with minimal interval

            //Timer.Start(1);
            //start timer with 1 second interval
        }

        protected override void OnTimer()

            copy_to_clipboard();

        }

            string ClipboardData = "";
            double AskEUR_CT = 0;
            double BidEUR_CT = 0;



            Symbol EUR = MarketData.GetSymbol("EURGBP");
            Symbol USD = MarketData.GetSymbol("GBPUSD");
            Symbol CHF = MarketData.GetSymbol("GBPCHF");
            Symbol JPY = MarketData.GetSymbol("GBPJPY");

            AskEUR_CT = EUR.Ask;
            BidEUR_CT = EUR.Bid;

            ClipboardData = AskEUR_CT.ToString("0.00000") + "," + BidEUR_CT.ToString("0.00000") ;
            Clipboard.Clear();

        protected override void OnStop()
        {

            //  Timer.Stop();
        }


    }
}

its a little changed from the first version (do not write to csv file), but the error is the same. Obviously its related to clipboard work. And I'm using OnTimer method.

You are right, time in the left column is your local time. You can add Server.Time to the Print statement.

Problem solved ... the system time was wrong ... I have to find a way the system timer to stay always same with the server time ?!?

Hello,

I worked on the following code and its not working very well:

var dailyEurGbpSeries = MarketData.GetSeries("EURGBP", TimeFrame.Minute);
var dailyClose = dailyEurGbpSeries.Close.Last(1);

 

I'm starting this code on tick graph with the idea to get the last M1 close (not current). I added Print(dailyClose) to the code and the result was strange.

07/08/2014 22:15:59.909 | GBP, EURGBP, t1 | Previous Close is0.79377

07/08/2014 22:16:00.143 | GBP, EURGBP, t1 | Previous Close is0.79377

07/08/2014 22:16:00.564 | GBP, EURGBP, t1 | Previous Close is0.79377

...

07/08/2014 22:16:06.211 | GBP, EURGBP, t1 | Previous Close is0.79377

07/08/2014 22:16:06.243 | GBP, EURGBP, t1 | Previous Close is0.79381

As you see it took 6 seconds to show me the true Close M1. Where is the mistake ?

 

First of all, please rename dailyEurGbpSeries variable, because it is minute, not daily series. It is not clear why do you think that GetSeries took 6 seconds. Please try to clarify your question.

The code is ran on 1 tick graph. It is made every tick to show me Previous 1 Minute Close using above example.

From the above raport, there are 5 given only tick raport from a minute 22:16 ... until 22:16:06.211 the script shows Close Quote from minute 22:14 ... from 22:16:06.243, the script shows close quote from minute 22:15.

Normally, the Last Minute close have to be given after 22:15:59.909 ... am I right ?

or Is it possible the fiven time to be client time, not server time ?

When my broker agent told me about cTrader, he assured me that there is a great tutorial and very useful forum when I can receive information about the coding ? Any idea why he lied me ? One WEEK I can't receive an answer of simple question ?! I suppose its better to rethink the idea of using non supporting software for trading.

Hello,

I got a problem using the clipboard. I got data in the clipboard that I want to assign it on a variable. I found a post in the forum

/forum/cbot-support/799

but i have trouble with it, I suppose because I have no reference to System.Windows.Forms.dll ... I have no this DLL and have no idea how to make this reference to cAlgo.

Please provide me with step by step tutorial how to deal with the DLL and assign the clipboard data to a variable.

 

Thank you in advance.

I found the button Manage References and made the reference to .net framework. So how to get data from clipboard ?

5. Of cource for observation needs, I need a code that places datas every tick in CSV file like ask(bid) quotes, server time (hour,minute, second, millisecond), connection speed to the server, current order (type (buy,sell),SL, TP, volume, magicnumber)

You can find an example of writing to a CSV file there: /algos/cbots/show/495. You will need to put your to code to the OnTick handler. You can retrieve prices from Symbol.Ask and Symbol.Bid properties. Server.Time property has DateTime value which stores hour, minute, second and millisecond. Connection speed is not available in the API. There is no current order entity in our API. You can enumerate all Positions with foreach instruction. All position properties are presented there: /api/reference/position.

I can't handle this :(

I'm trying to save data every tick Ask and Bid together with Data and HH:MM:SS.mmm in CSV file. The problem is that the code saves me only last data. Please tell me where I'm wrong.

using System;
using System.Globalization;
using System.IO;
using System.Linq;
using System.Threading;
using cAlgo.API;
using cAlgo.API.Indicators;

            Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
            var desktopFolder = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
            var folderPath = Path.Combine(desktopFolder, "cTraderData");
            Directory.CreateDirectory(folderPath);
            var filePath = Path.Combine(folderPath, Symbol.Code + "-" + Server.Time.Day + "-" + Server.Time.Month + "-" + Server.Time.Year + ".csv");

            using (var writer = File.CreateText(filePath))
            {

                writer.WriteLine(ConcatWithComma(Server.Time.Date, Server.Time.TimeOfDay, " ", Symbol.Ask, Symbol.Bid));

            }//using
        }//onTick

    }//DumpCSV
}//cAlgo

Aslo, I can't put on the first row label of colomns and can't add properly mileseconds to the HH:MM:SS.mmm ...

Also any ideas how to put working directory different than Desktop (maybe without granting full access rights ?). Thanks in advance

3. When I make an order, then its possible to change StopLoss and TakeProfit of this order. On MT4 there was a possible Stoploss and TakeProfit (pips away from current price). Is there something in cTrader and how to get this possible Stoploss and TakeProfit

There is no restriction for minimal pips away from spot prices.

6. How much money i have to possess in mu account to buy the minimum 10k eurusd, or 10k gold ... etc ... newbee question.

In order to calculate required margin you can use the following formula:

        private double GetRequiredMarginForLongPosition(long volume, Symbol symbol)
        {
            return volume / Account.Leverage * symbol.Ask * symbol.TickValue / symbol.TickSize;
