Lot size

New comment

SteeveNi25 2021.06.10 06:50

I need help for my code plz

I want to increase the lot size every month only

For eg:

This code should be calculated from the initial balance of the month

If the initial balance is 1000usd in 1january

1050usd in 2 january

.........

2100usd in 31 january

So during this month,the AccountBalance() should be always 1000usd because it's the initial balance

For the next month(february), the //Lot code should be actualised,I mean,if the balance become 2200usd,the AccountBalance should be calculated from this new account balance on first of february(AccountBalance()=2200usd) .... and soon as

Lots=(((AccountBalance() * MaximumRisk / 100) / (StopLoss))); //Lot code

//--- SELL 
   ma12=iMA(NULL,PERIOD_M15,12,0,MODE_EMA,PRICE_MEDIAN,1);
   ma4=iMA(NULL,PERIOD_M15,4,0,MODE_EMA,PRICE_TYPICAL,1);//--- sell conditions
   if(TimeCurrent()>StrToTime(TradeStartTime) && TimeCurrent()<StrToTime(TradeStopTime)
     && (ma4<ma12) && CandleSell && !isWhiteHammer01 && !neutralSell && !WarningTradeSell && !WarningTradeSell1)
     {

      if(sl==TRUE){
         if(MathRound(closeM5-ma)/Point<=500)
            {_sl=600;}
         else _sl=MathRound(closeM5-ma)/Point;
      double StopLoss=1.5*_sl*Point;

Hi,

it looks a little bit difficult, but one way to solve your problem is to save the AccountBalance
in a file on the first day of the month and read the value on the other days out of that file.

Best regards,

Using data from demo Expert log size modification I have a problem

Best regards,

Can you give a little function to save an information in the file and to read it?plz

Werner Klehr 2021.06.10 07:43 #3

Hi,

this little function should do what you want:

double GetInitAccount()
{
        int FileHandle;
        string FileName = "MyAccountBalance.dat";
        double InitAccount = 0.0;

        if ((TimeDay(TimeCurrent()) == 1) && (TimeHour(TimeCurrent()) == 6) && (TimeMinute(TimeCurrent()) == 0) && (TimeSeconds(TimeCurrent()) < 5))
        {
                FileHandle = FileOpen(FileName, FILE_WRITE); 
                if (FileHandle == INVALID_HANDLE)
                {
                        Print("FileOpen failed / FileName: " + FileName + " / Error: " + IntegerToString(GetLastError()));
                        return(-1.0);
                }

                InitAccount = AccountBalance();
        
                FileWriteDouble(FileHandle, InitAccount);
                FileClose(FileHandle);
        }
        else
        {
                FileHandle = FileOpen(FileName, FILE_READ); 
                if (FileHandle == INVALID_HANDLE)
                {
                        Print("FileOpen failed / FileName: " + FileName + " / Error: " + IntegerToString(GetLastError()));
                        return(-1.0);
                }
        
                FileReadDouble(FileHandle, InitAccount);
                FileClose(FileHandle);
        }

        return(InitAccount);
}

The file will be saved in the MQL4/Files subfolder.

I hope this will help you.

Best regards,

Thanks so much, I will try it now

Werner Klehr 2021.06.10 08:20 #5

Hi,

i'm sorry, but i think i forgot a little thing: you must use the FILE_BIN Option in the FileOpen statement - the
correct code should look like this:

double GetInitAccount()
{
        int FileHandle;
        string FileName = "MyAccountBalance.dat";
        double InitAccount = 0.0;

        if ((TimeDay(TimeCurrent()) == 1) && (TimeHour(TimeCurrent()) == 6) && (TimeMinute(TimeCurrent()) == 0) && (TimeSeconds(TimeCurrent()) < 5))
        {
                FileHandle = FileOpen(FileName, FILE_WRITE | FILE_BIN); 
                if (FileHandle == INVALID_HANDLE)
                {
                        Print("FileOpen failed / FileName: " + FileName + " / Error: " + IntegerToString(GetLastError()));
                        return(-1.0);
                }

                InitAccount = AccountBalance();
        
                FileWriteDouble(FileHandle, InitAccount);
                FileClose(FileHandle);
        }
        else
        {
                FileHandle = FileOpen(FileName, FILE_READ | FILE_BIN); 
                if (FileHandle == INVALID_HANDLE)
                {
                        Print("FileOpen failed / FileName: " + FileName + " / Error: " + IntegerToString(GetLastError()));
                        return(-1.0);
                }
        
                FileReadDouble(FileHandle, InitAccount);
                FileClose(FileHandle);
        }

        return(InitAccount);
}

Best regards,

I tried to Alert the initial balance after reading the write file for verification but it does not give a value, however it should give the balance at (TimeDay(TimeCurrent()) == 4) && (TimeHour(TimeCurrent()) == 6) && (TimeMinute(TimeCurrent()) == 0) && (TimeSeconds(TimeCurrent()) < 5)

int FileHandle;
        string FileName = "MyAccountBalance";
        double InitAccount = 0.0;

        if ((TimeDay(TimeCurrent()) == 4) && (TimeHour(TimeCurrent()) == 6) && (TimeMinute(TimeCurrent()) == 0) && (TimeSeconds(TimeCurrent()) < 5))
        {
                FileHandle = FileOpen(FileName, FILE_WRITE | FILE_BIN); 
                if (FileHandle == INVALID_HANDLE)
                {
                        Print("FileOpen failed / FileName: " + FileName + " / Error: " + IntegerToString(GetLastError()));
                        return(-1.0);
                }

                InitAccount = AccountBalance();
        
                FileWriteDouble(FileHandle, InitAccount);
                FileClose(FileHandle);
        }
        else
        {
                FileHandle = FileOpen(FileName, FILE_READ | FILE_BIN); 
                if (FileHandle == INVALID_HANDLE)
                {
                        Print("FileOpen failed / FileName: " + FileName + " / Error: " + IntegerToString(GetLastError()));
                        return(-1.0);
                }

                FileClose(FileHandle);

        return(InitAccount);

How to code? INVALID_TRADE_PARAMETERS HELP [ARCHIVE!] Any rookie question,

What if there are no ticks during a specific candle period? There can be minutes between ticks during the Asian session, think M1 chart.

So it should be like this?

isn't i?

(TimeDay(TimeCurrent()) == 4) && (TimeHour(TimeCurrent()) == 6) && (TimeMinute(TimeCurrent()) == 0) && (TimeSeconds(TimeCurrent()) < 60)
