Vladimir:

Why just for this, such a simple theory about the impossibility of winning without a prediction? I didn't say that... This amount of data is interesting in itself, there are 80 billion of them now. And the implications of this theory are many, in particular, the hopelessness of any martingale scheme, however twisted. And also other series, which are not based on predictions, but on very different signs, not related to the prediction.

If you open randomly, yes, expectation of profit is exactly equal minus spread. Signals are another matter, they may have their own expected payoff characterizing the quality of their forecasts. But it cannot be estimated, we can only take a sampling average, not expected value. And I think, I don't need to tell you how samples are created.

Am I right to understand that you use statistical data in trading and select corresponding mm to shift the expected payoff in positive direction? I.e., a knowingly losing strategy may turn out to be profitable with certain mm and constant statistical processing?

No, a knowingly losing strategy (with expected payoff less than zero) cannot become profitable by any trading volume management. Basically this data is used to test hypotheses. Of course, to simulate real trading. It also finds out who quotes how.

mt4 used to be able to optimise an EA, but now there is no optimisation checkbox

Gentlemen, is there a BB indicator that would just give an audible signal when the upper and lower line is broken and I would make my own decision on the trade?

Hello! Here is the situation:

There is an indicator that opens a currency pair chart under certain conditions and applies a template to it, with an EA. When I manually apply a template in the terminal,"Allow the EA to trade" is checked, but when the template is loaded programmatically, this option is disabled, is it possible to correct?

Can you suggest a broker with MT4 or MT5 that has Petrol and Fuel Oil quotes?

Hello, can you tell me how to calculate the losing orders going in a row? And with a profitable one, the account would go to zero. I invented something, but I don't have enough...

int LossOrders()
{
int oldticket;
ticket = 0;

for (i = OrdersHistoryTotal() - 1; i >= 0; i--)
{
if (OrderSelect (i, SELECT_BY_POS, MODE_HISTORY))
{
if (OrderSymbol() == Symbol() && OrderMagicNumber() == magic)
{
oldticket = OrderTicket();
if (oldticket > ticket)
{
ticket = ticket;
if(OrderProfit()<0)
{
orderloss++;
}else orderloss=0;
}
}
}
}
return(orderloss);
}

Here

int LossOrders()
  {
   int orderloss=0;
   int total=OrdersHistoryTotal();

   for(int i=0;i<total;i++)
     {
      if(!OrderSelect(i,SELECT_BY_POS,MODE_HISTORY))continue;
      if(OrderMagicNumber()!=magic)continue;
      if(OrderSymbol()!=Symbol())continue;

      if(OrderProfit()<0)orderloss++;
      else orderloss=0;

     }
   return(orderloss);
  }

Hello.

Is it possible to find out the actual spread values in the past ?

Thank you.
