Help write a function that returns the bar of the last MA crossing, given that there are 10 bars between the last and penultimate crossing and from the point of last crossing to the minimum there is a given number of points. for the third day I'm struggling all is not working out a file with the code attached

Frankly, I have exhausted myself but still do not understand how to reproduce these calculations in Five:

//--- counted in the 1-st buffer
   for(i=0;i<limit;i++)
     {
      int bars=iBarShift(Symbol(),PERIOD_M1,iTime(Symbol(),PERIOD_CURRENT,i),false);
      ExtBuffer[i]=(
                    iMA(NULL,PERIOD_CURRENT,1,0,MODE_SMA,PRICE_HIGH,i)
                    +iMA(NULL,PERIOD_M1,1,1,MODE_SMA,PRICE_OPEN,bars)
                    );
      Print(bars);
     }

I suggested a universal code

Try

int  Bars(
   string           symbol_name,     // имя символа
   ENUM_TIMEFRAMES  timeframe,       // период
   datetime         start_time,      // с какой даты
   datetime         stop_time        // по какую дату
   );

Time the i-th bar and put the resulting bar number instead of i.

It works in both mql4 and mql5.

I immediately suggested a universal code

it works in mql4 and mql5.

But how in 5 to get

start_time,      // с какой даты

there

iTime()

does not work.

does not work.

CopyTime works.

But it is not needed in this case, because time of current period is in time[i], it's an indicator...

iTime(Symbol(),PERIOD_CURRENT,i) == time[i]

Hi all. Help me with OrderProfit() function. How to make Comment display the current profit of all open orders. I get the same number.

double CalcProfit()

{

double Profit = 0;

for (int i=OrdersTotal() - 1; i>=0; i--)

{

if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES))

{

if (OrderSymbol() == Symbol() && OrderMagicNumber() == Magic)

{

if (OrderType() == OP_BUY)

{

Profit += (OrderProfit() + OrderSwap() + OrderCommission())

}

}

}

}

return(Profit);

}

How to make the value of the profit change accordingly with each tick (price change).

That's it. Got it.

I personally first write in 4-Rock, then I change it to 5-Rock, otherwise it's too much trouble for me, because 5-Rock code is harder to read, functions are too long in number of letters..., so it turns out the text for gum scholars, not for engineers ))))

and behold
