Hi,

I have a strategy which works in Historical Tester while backtesting and when I run the strategy in DEMO Remote Server it exits. I believe the line in red is the problem as it runs properly when I remove it and hard code a value for pipAmount. The blue line is from the log of the backtest, showing that it works as expected by returning a value of 0.00009. API Version is 3.0.18.

acc=USD ins=GBP/JPY getEquity=48935 getBalance=48935 slPips=0.24000 riskAmount=979 pipAmount=0.00009 pipValue=0.01000 slPips10=24.00000 riskPips=207.98489 lots=0.47000 riskPips2=200.49435 lots2=0.98000 position=0.66000

Here is the method and the erroneous line is below in red, basically the first line of code. Now is this a bug? It would seem so if it works in one environment and not another.

double pipAmount = myJFUtils.convertPipToCurrency(tradeIns, myAccount.getAccountCurrency());

Thanks,
Chrysos.

    private double calculatePosition(int posType, Instrument tradeIns, double getEquity, double entry, double slPips, double atrPips, double pipValue) throws JFException {
        double pipAmount = myJFUtils.convertPipToCurrency(tradeIns, myAccount.getAccountCurrency());
        double riskAmount = getEquity * (myRisk / 100d);
        double slPips10   = slPips / pipValue;
        double riskPips   = slPips10 * pipAmount * 100000d;
        double lots       = round((riskAmount / riskPips) / 10d, 2);
       
        double atrPips10  = atrPips / pipValue;
        double riskPips2  = atrPips10 * pipAmount * 100000d;
        double lots2      = round((riskAmount / riskPips2) / 10d, 2) * 2d;
        
        double position = round((((myRisk / 100d) * getEquity * entry) / (slPips * pipAmount * 10000d)) / 1000000d, 2);
       
        print2(String.format("acc=%s ins=%s getEquity=%.0f getBalance=%.0f slPips=%.05f riskAmount=%.0f pipAmount=%.05f pipValue=%.05f slPips10=%.05f riskPips=%.05f lots=%.05f riskPips2=%.05f lots2=%.05f position=%.05f",  myAccount.getAccountCurrency(), tradeIns, getEquity, myAccount.getBalance(), slPips, riskAmount, pipAmount, pipValue, slPips10, riskPips, lots, riskPips2, lots2, position));

             if (posType == 1)
                 return lots;  
        else if (posType == 2)
                 return lots2;
       
        return lots;
    } 

Cannot reproduce. Please, provide strategy example.

Hi and thanks for the response,

I'd like to do that but I'd like to run the strategy with the latest API, but now that has given me trouble. Here's the errors I get.

It says line 8 of the POM file is in error. Line 8 is the 2nd line below.

For some reason Maven doesn't see JForex API jar file.
1)Check location('C:\Users\CHRYSOS\.m2\repository\com\dukascopy\api\JForex-API\2.13.46\JForex-API-2.13.46.jar') for the presence of jar file.
2)Open cmd from JForex SDK folder and do 'mvn clean install'

Hi,

I tried what you suggested - go to CMD in the JForex-3-SDK directory and it said command 'mvn' and 'mvn clean install' not a recognized internal, external or batch command.

Here is what is in directory of C:\Users\CHRYSOS\.m2\repository\com\dukascopy\api\JForex-API\2.13.46

It seems the JForex-API-2.13.46.jar file has a Type of LASTUPDATED as well as .lastUpdated extension and the dates are 26/12/2017.

Can I back out of this and install the SDK as I did the very first time? I have the code saved elsewhere and I can just copy it. That means I would have to delete the .m2 directory and what else?

Thanks,
Chrysos.

Seems like you have some problem with dependency references in pom.xml. Have you also updated JClient version? You can copy and post here all code inside <dependecies></dependecies> tags
And i advise you to install Maven: https://maven.apache.org/install.html

I haven't updated the JClient but I did install Maven and run the command 'mvn clean install'. I now have 3 errors but importantly, my Java strategy is error free and compiles. However, it behaves worse than before. It only runs for a couple of minutes and stops even though I have commented the line I think is the problem.

Now this line causes a problem.

IBar prevBar = myHistory.getBar(instrument, period, OfferSide.BID, 1);

Please tell me how to completely uninstall everything so I can install it all again so I can start as new.

I delete the workspace, then what about directory C:\Users\CHRYSOS\.m2, C:\Users\CHRYSOS\.jmc ?

Alright, I've fixed the problems with the API, but the original strategy problem still stands. It runs in backtest, but not in real time DEMO. How can I look at the log of it running on real time DEMO? The logs in C:\Users\UserName\JForex\logs do not seem to show where the error occurs.

Here is the error. I then comment some code out and get the second error - overload. What is wrong? How can I look at the logs to fix this? There appear to not be too be useful logs for Remote Server strategies. The strategy subscribes to 15 instruments. It would seem this might cause a problem, but why?

By this information isn't possible to identify problem.
Write on [email protected]. Attach your strategy

Thanks,

I am going to try to add some asynchronous coding for subscribing to instruments and getting historical data and then send the strategy to support.

Regards,
Chrysos.
