RE:

Hi,

I have solved this as following:

// For xxx.yyy and x.yyyyy currencies listed in setVolumeConverter()
                int lots = (int)(Risk/(riskInPips/volumeConverter));                

                lots = lots/10000; lots = lots*10000; // Round off using integer truncation
 
                Volume = lots;

The volumeConverter is set when the robot starts using this: setVolumeConverter();

The setVolumeConverter() method looks like this:

 private void setVolumeConverter()            
            {
            
            switch (Symbol.Code)
            {
             // x.yyyyy currencies  
                case "EURUSD":volumeConverter = 1;
                break;
                case "USDCAD":volumeConverter = 1;
                break;
                case "EURCAD":volumeConverter = 1;
                break;
                case "GBPCHF":volumeConverter = 1;
                break;
                case "GBPUSD":volumeConverter = 1;
                break;
                case "EURAUD":volumeConverter = 1;
                break;
                case "AUDCAD":volumeConverter = 1;
                break;
                case "EURTRY":volumeConverter = 1;
                break;
                case "AUDUSD":volumeConverter = 1;
                break;
                case "GBPAUD":volumeConverter = 1;
                break;
                case "USDSGD":volumeConverter = 1;
                break;
                case "GBPCAD":volumeConverter = 1;
                break;
                case "USDCHF":volumeConverter = 1;
                break;
                case "EURGBP":volumeConverter = 1;
                break;                 
                case "NZDUSD":volumeConverter = 1;
                break;
                // xxx.yyy currencies   
                case "EURJPY":volumeConverter = 100;
                break;
                case "GBPJPY":volumeConverter = 100;
                break;
                case "USDJPY":volumeConverter = 100;
                break;
                case "CADJPY":volumeConverter = 100;
                break;
                case "AUDJPY":volumeConverter = 100;
                break;
                }
            Print("volumeConverter: {0}", volumeConverter);
           }

This solution is not particularly elegant. Maybe someone has a better solution?

RE:

Hi,

from what I have read I don't think you can use a boolean as a parameter.

To solve this I use an integer and set it to 1 or 0 (to represent true and false).

I would rather use a boolean as the user would be restricted as to what input they can enter, and the programming is neater. But as the user is me and I know not to enter a different value it works.

The entry above did not display the pasted in  images, so I will try again:

----------------------------------

Hi,

1. If I set the default value of a parameter to 0 0.00015 value is shown in the parameter list as expected:

      [Parameter("Better entry ", DefaultValue = 0.00015, MinValue = 0)] // Try to get a better entry than the signal
      public double BetterEntry { get; set; }   

Note: This value is greater than one pip (AUDUSD)

But:

2. If I set the default value for the parameter to be less than 0.0001 like this:

      [Parameter("Better entry ", DefaultValue = 0.00005, MinValue = 0)] // Try to get a better entry than the signal
      public double BetterEntry { get; set; }   

the display shows the following:

Note: Trying to enter a value less than one pip (AUDUSD) fails.

3. Also if I use the parameter set in 1. above and enter 0.00005 by hand the 5E-05 is displayed as in 2:

This is awkward as I cannot enter a value in the interface to be less that one pip.

Why does this happen? Is this wanted behaviour?

Thanks,

Hi,

good news - the plaform ran all last week (with two robots running on Win 8) with no problems. The only known difference is that I deinstalled the Norton Online Backup.

I will update this post if the error appears again.

Hi,

the platform ran as expected until the end of the week when the same error occured again.

However I have noticed that two programs are active near the time of the crash (which seems to occur at a regular time):

- antivirus (update)

- Norton Online Backup (reminder to update)

I have now deinstalled Norton Online Backup.

It is awkward to sync the out of memory error with the event writer logs as I cannot get an exact time when the problem occurs (as I cannot watch the computer constatntly). But I think I will get there in the end.

The next step will be to run the platfrom again without Norton, then if the error still occurs try another antivirus. And keep watching the event writer.

I will keep you posted with any developments.

Hi,

I will run the robot another week real time just to check that the error does not result from network problems (to save you going through the code).

I would still be interested if there are additional error codes related to an Order Execution Error which I can intercept.

I know about these:BadVolume, TechnicalError, NoMoney, Disconnected, MarketClosed

Are there any other error messages that might relate to an Order Execution Error?

Thanks,

Hi, does this only work in real time? Backtesting, I get nothing written to the screen.

The example in the API reference under DrawText (example 1) starts:

if(IsRealTime)
....

which implies that this is indeed a solution for real time. If so, is it possible to write to the chart when backtesting?

What I really want to do is to highlight in the charts where I create/delete pending orders, enter and exit  trades and so on, when back testing. Currently I have to find the places in the charts going back and forth using the account history or the log with my Print functions. This takes ages...

Any ideas how to do this?
