How to reduce the number of deals in a strategy tester?

T-G 2010.07.14 08:19 #7011

keekkenen:

static int time = Time[0];

if (time < Time[0]){

// old candle

} else {

// new candle

time = Time[0];

}

There are now half as many deals as there were before

T-G:
Now the trades are half as long as they were before

Instead of checking for a new bar, just pause between openings, set in seconds:

//|  Описание : Возвращает количество секунд после открытия последней позиций. |
//+----------------------------------------------------------------------------+
//|  Параметры:                                                                |
//|    sy - наименование инструмента   (""   - любой символ,                   |
//|                                     NULL - текущий символ)                 |
//|    op - операция                   (-1   - любая позиция)                  |
//|    mn - MagicNumber                (-1   - любой магик)                    |
//+----------------------------------------------------------------------------+
datetime SecondsAfterOpenLastPos(string sy="", int op=-1, int mn=-1) {
  datetime t;
  int      i, k=OrdersTotal();

  if (sy=="0") sy=Symbol();
  for (i=0; i<k; i++) {
    if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
      if (OrderSymbol()==sy || sy=="") {
        if (OrderType()==OP_BUY || OrderType()==OP_SELL) {
          if (op<0 || OrderType()==op) {
            if (mn<0 || OrderMagicNumber()==mn) {
              if (t<OrderOpenTime()) t=OrderOpenTime();
            }
          }
        }
      }
    }
  }
  return(TimeCurrent()-t);
}

I check it this way (in bold, ignore /*PauseMain*/ - it's a random value of delay in minutes - from 5 to 9):

// Тут начало функции открытия позиций (открытие Buy)....

// Ниже код открытия Sell:        
          PauseMain51=random(5,9)*60;
         if (!Lot()) return;               // Средств не хватает на миним.- выходим
         if (!OpnSell51 || !Trade) return;
         if (ExistPositions(NULL, OP_SELL, 51, 0))  // Если есть такой же открытый Sell
               {
                 if (SecondsAfterOpenLastPos(NULL, OP_SELL, 51)<=/* PauseMain51*/ 7*60) return; (7*60 сек = 7 минут)
                  // Если прошло мало времени - валим
               }
//---------------------- Позиции ещё нету - открываемся...-----------------------------
         divider=1;
         Lots=GetSizeLot();
         Magic=51;                                          // Задаём магик... 5 и 1; 5 = пять минут, 1 = стратегия 1
         New_Comm="Sell_M5_Стратегия_1_Основная позиция";   // Задаём комментарий для позиции
         Lots_New=NormalizeLot(Lots/divider, False, NULL);
         OpenPosition(NULL,OP_SELL,Lots_New,0,pb-tp*po,Magic,New_Comm);

         return;

I hope it makes sense...

Question - is it possible that graphical objects are not simulated in the strategy tester in the non-visual mode? For example, I was testing code that opens trades by breaking the channel OBJ_REGRESSION - it trades in the visual mode, but if I turn it off, there are no trades... How to conduct optimization in this case?

Any rookie question, so Strategy tester not working Questions from Beginners MQL5

ToLik_SRGV:

Boris, small correction in the code, forgot to add a reset of the array position, when returning to the original lot:

THANK YOU VERY MUCH! Everything worked out. Goes well and puts the right lots!!!

Please tell me what to do and change or add to the code to set the bar width of the histogram?

Igor Makanu 2010.07.14 14:23 #7016

How can I change or add something to the code to set the bar width in the histogram?

in indicator settings - line type, colour and width/thickness

odiseiff 2010.07.14 14:30 #7017

IgorM:

in the indicator settings - line type, colour and thickness/width

SetIndexStyle(0, DRAW_NONE);
SetIndexStyle(1, DRAW_LINE,EMPTY);
SetIndexStyle(2, DRAW_NONE);
SetIndexStyle(3, DRAW_NONE);
SetIndexStyle(4, DRAW_NONE);
it's here ....... but my tool has a line width of 0 and I want to set the width of 2 so I don't have to deal with settings ...... I don't know how to do it .... I'm not a programmer .... help me please ))))

Variables with SetIndexStyle? Histogram Lines to size SetIndexStyle(2,DRAW_HISTOGRAM,0,5,Lime); DOES NOT work

I don't know anything about programming at all. I wanted to make CCI Filter (https://www.forex-tsd.com/indicators-metatrader-4/3356-cci-filter.html) the same for WPR, changed CCI to WPR and changed levels in coloring conditions of bars (not -100, 0, 100 like CCI, but -60, -50 and -40, because in MT WPR has range -100 to 0, I think, right?) But for some reason it compiles with an error, and the screen shows a monochrome indicator. What is wrong? Thanks in advance

Infinity:

Memory is useless).

I want to know what kind of currency, prescribed the variables

string EUR="EURUSD";
string GBP="GBPUSD";

string symbl = "";

I write the following at start :

symbl = symbl(); //receive the value of the symbol

I want to compare the received value of symbl with the values of my variables, and if they match, then make a decision.

switch (symbl) {

case .......... then nothing happens (( break;

case ................ break;

}

Refresh my memory))

I figured out that only a character constant can be used, but how do I do it?
