MetaTrader 4 - Minimum Lot Size in offline mode

New comment
 

Hello,

When I am using MT4 in online mode with my current broker (Oanda) I can use 2 digit lot sizes (e.g: 0.11) but if I do backwards testing on a weekend where I have to use the offline mode in order to be able to use the weekday spreads and not the week-end spreads for the whole testing I can only use 1 digit lot sizes (e.g 0.1). If I try to use 2 digit lot sizes I am getting a 131 error.

Does anyone know where to set the amount of lot size digits for the offline mode?

Thanks,

Wolfgang

 
More likely the problem is not offline but your code (which you don't show and there are no mind readers here.)
double NormalizeLots(double lots, string pair=""){
    if (pair == "") pair = Symbol();
    double  lotStep     = MarketInfo(pair, MODE_LOTSTEP),
            minLot      = MarketInfo(pair, MODE_MINLOT);
    lots            = MathRound(lots/ls) * ls;
    if (lots < minLot) lots = 0;    // or minLot
    return(lots);
}
 

There is no magic here .... I am just using the OrderSend method:

ticket=OrderSend(Symbol(),OP_BUY,volume,Ask,Slippage,StopLossLevel,TakeProfitLevel,comment,12345,0,LongOrderColor);

I can run it with a volumne of 0.12 in online mode and in offline mode it will throw an error 131.

The issue is that ...

MarketInfo(Symbol(), MODE_LOTSTEP)

returns 0.01 in online mode and 0.1 in offline mode. WHY??????

I thought you were talking about running the tester without a net connection to control the spread. Nothing should be changing. Describe exactly your procedure. Did you install in \program files* on Vista/Win7?

Are you talking about an offline chart, like Renko, Range bars etc.? You can not use MarketInfo(Symbol(), ...) or MarketInfo(NULL, ...) because the server has no knowledge of an offline chart. You must use the REAL symbol for those values.

 

Yes. MT4 is install ed in c:\Program Files\ on Win7.

The data I am using was downloaded from histdata.com.

MarketInfo("AUDNZD", MODE_MINLOT)

is returning 0.1 as well. It should return 0.01

 
Im running into this exact problem right now,  and have no idea how to proceed
