Can you please tell me how to use bollinger bands for momentum, not for price? I tried it like this:

BandOPeriodT - external variable, period of bollinger bands.

MomentumPeriodT - period of momentum, respectively.

BandOBottom=iBands (NULL,0,BandOPeriodT,1,0,iMomentum(NULL,0,MomentumPeriodT,PRICE_OPEN,0),MODE_LOWER,0);

and also like this:

MomO=iMomentum(NULL,0,MomentumPeriodT,PRICE_OPEN,0); - internal variable which returns the value

BandOBottom=iBands(NULL,0,BandOPeriodT,1,0,MomO,MODE_LOWER,0); - the variable should return the value of the lower Bollinger line for the previous variable value.

Also, am I right in assuming that MODE_LOWER means I get the value of BOLLINGER BOLLINGER in a variable? If not, how do I get it exactly?

See trailer - there Bands for RSI - do the same for Momentum.

Description - in the log - see code at the beginning.

Thank you, because I'm very new, and not much of a programmer either:)

Let us assume that the open position has already been selected and we know for sure that this position is opened
for the symbol to which the Expert Advisor is attached. Also assume that the value of trailing stop
in pips is contained in the TrailingStop variable.

   int err;
   if (OrderType() == OP_BUY)
     {
       // позиция на покупку
       if ((Bid-OrderOpenPrice())>=(TrailingStop*Point))
         {
           // выставляем Stop Loss
           if (OrderModify(OrderTicket(), OrderOpenPrice(), Bid-TrailingStop*Point,
                                    OrderTakeProfit(), 0))
             Print("#", OrderTicket(),": trailing stop ", Bid-TrailingStop*Point);
           else
             {
              err = GetLastError();
              Print("#", OrderTicket(),": trailing stop error ", err);
             }
         }
     }
   else
     {
       // позиция на продажу
       if ((OrderOpenPrice()-Ask)>=(TrailingStop*Point))
         {
           // выставляем Stop Loss
           if (OrderModify(OrderTicket(), OrderOpenPrice(), Ask+TrailingStop*Point,
                                    OrderTakeProfit(), 0))
             Print("#", OrderTicket(),": trailing stop ", Ask+TrailingStop*Point);
           else
             {
              err = GetLastError();
              Print("#", OrderTicket(),": trailing stop error ", err);
             }
         }
     }

The OrderProfit() function returns the profit for the order selected using the OrderSelect() function.

Suppose that we want to calculate the profit that we have gained from closed positions.

   int profit = 0;
   int pos;
   for ( pos = 0; pos<HistoryTotal(); pos++ )
     {
       // выделим позицию
       if (OrderSelect(pos, SELECT_BY_POS, MODE_HISTORY) == true)
         {
           // это не отложенный ордер?
           if ( OrderType() <= OP_SELL) profit += OrderProfit();            
         }
       else
           Print("Ошибка ", GetLastError(), " при выделении ордера ", OrderTicket());
     }
   Print("Суммарный профит по закрытым позициям = ", profit);

And the full code that calculates the profit for all closed positions,
that are opened today, will be:

   //---- вычислим начало дня - переменная day_start
   int c_time = CurTime();  
   datetime day_start;
   day_start=c_time-TimeHour(c_time)*60*60-TimeMinute(c_time)*60-TimeSeconds(c_time);
   //---- подсчитаем прибыль
   int profit = 0;
   int pos;
   for ( pos = 0; pos<HistoryTotal(); pos++ )
     {
       // выделим позицию
       if (OrderSelect(pos, SELECT_BY_POS, MODE_HISTORY) == true)
         {
           // это не отложенный ордер?
           if ( OrderType() <= OP_SELL)
             {
               // ордер был открыт сегодня?
               if (OrderOpenTime()>=day_start) profit += OrderProfit();
             }
         }
       else
           Print("Ошибка ", GetLastError(), " при выделении ордера ", OrderTicket());
     }
   Print("Суммарный профит по закрытым позициям = ", profit);

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Maybe there is something else missing in the code:

double OrderLots(

)

Returns the number of lots for the selected order.
The order must be pre-selected using OrderSelect().

Example:

 if(OrderSelect(10,SELECT_BY_POS)==true) Print("lots for the order 10 ",OrderLots()); else Print("OrderSelect() has returned an error - ",GetLastError());

The PVT indicator itself is missing (are you sure you have one?).
