Good afternoon, all.

Try

//--ТРАЛ ПО ПАРАбОЛИКУ
void Tral_parabolik()
{ // НАЧАЛО ТРАЛ ПО ПАРАБОЛИК
//+------------------------------------------------------------------+
   int    Tral = tral;
   double Sar  = iCustom(_Symbol,PeriodForWork_tral_parabolik,"Parabolic",step_tral_parabolik,max_tral_parabolik,1);
//+------------------------------------------------------------------+
   for(int pos=0;pos<OrdersTotal();pos++)
     {
      if(OrderSelect(pos,SELECT_BY_POS,MODE_TRADES))
      if(OrderSymbol()==_Symbol)
        {
         if(OrderType()==OP_SELL)
           {
            if(OrderOpenPrice()>Ask+Tral*Point&&OrderOpenPrice()>Sar)
              {
               if(OrderStopLoss()!= Sar&&Sar>Ask)
                 {
                  if(OrderModify(OrderTicket(),OrderOpenPrice(),NormalizeDouble(Sar,Digits),OrderTakeProfit(),0,clrBlack))
                    {
                     Print("Order SELL Modify",GetLastError());
                    }
                 }
              }
           }

            if(OrderOpenPrice()<Bid-Tral*Point&&OrderOpenPrice()<Sar)
              {
               if(OrderStopLoss()!= Sar&&Sar<Bid)
                 {
                  if(OrderModify(OrderTicket(),OrderOpenPrice(),NormalizeDouble(Sar,Digits),OrderTakeProfit(),0,clrGreen))

Thanks for all the help BUT my brains are not enough to do what I need!

i mean like this ? only here the lot is increased when positions are in deficit - and you, i assume, need to increase when positions are in surplus ?

All profits depend on these two functions. You have to configure them properly and give them to a good Expert Advisor.

input string   t0="------------ Exchange TP SL --------"; //
input double   InpTProfit       = 10;            // Exchange TP
input double   InpStopLoss      = 1000000;       // Exchange SL
input string   t1="------------ Lots Parameters -------"; //
input double   InpLots1         = 0.01;          // : Lots 1
input int      InpLots_01       = 2;             // Exchange Lots
input double   InpLots2         = 0.03;          // : Lots 2
input int      InpLots_02       = 4;             // Exchange Lots
input double   InpLots3         = 0.06;          // : Lots 3
input int      InpLots_03       = 8;             // Exchange Lots
input double   InpLots4         = 0.12;          // : Lots 4

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

and this is from the Expert above - which is just an example

all profit - depends on these two functions . You just need to set them up properly and cram them into a normal Expert Advisor

Need help! How to create an array for iCustom to find the nearest value not equal to 0? MT4

 

Fellow traders!

How to combine iLowest (the smallest value in x bars) and iAD indicator value (which does not give percentage data but actual data in pips), the smallest value in x bars according to iAD is needed. Thank you. МТ4

Работа по Накоплению/Распределению и что из этого можно сделать
  • www.mql5.com
Индикатор Накопления/Распределения A/D имеет одно интересное свойство - пробитие трендовой линии, построенной на графике данного индикатора с определённой долей вероятности говорит нам о скором пробое линии тренда на графике цены. Данная статья будет полезна и интересна людям, только начинающим программировать на MQL4, поэтому я постарался изложить всё в наиболее доступной для понимания форме и использовать самые простые конструкции построения кода.

Hello. Can you tell me if the Roll Over thing is still on? I can't remember the last time it was on.
