Friends, please help!!! I cannot write a code that would open a buy if the price goes from the bottom to the top of a certain level, and for sell - vice versa. I can't decide if the price comes from the bottom or the top.

Many variations are possible.

For example:

 double price1 = iClose(NULL,0,1);           // Цена закрытия последнего сформированного бара
 double price2 = iClose(NULL,0,2);           // Цена закрытия второго (предпоследнего) бара 
 double Level = 1.7658;                      // Какой-то уровень
 
 if(price1>Level && price2<Level)OrderSend(Symbol(),OP_BUY,......); // Если цена на предпоследнем баре была ниже уровня, 
                                                                    // а на последнем выше, то покупаем...
 if(price1<Level && price2>Level)OrderSend(Symbol(),OP_SELL,......);

What if one of the prices is equal to Level ?

What about the zero bar? It is the very first one. But it has not been formed yet. You confuse the person. Then it is like this:

//----------------------------------------------------------------------------------------
int    dg=MarketInfo(Symbol(),MODE_DIGITS);
double price1 = iClose(NULL,0,1);           // Цена закрытия первого бара
double price2 = iClose(NULL,0,2);           // Цена закрытия второго бара 
double Level = 1.7658;                      // Какой-то уровень
 
   if (NormalizeDouble(price1-Level,dg)>0 && NormalizeDouble(Level-price2,dg)>=0) {
      // ... код открытия позиции Бай ...
      }
   if (NormalizeDouble(Level-price1,dg)>0 && NormalizeDouble(price2-Level,dg)>=0) {
      // ... код открытия позиции Селл ...
      }
//----------------------------------------------------------------------------------------

Again.

There are very(!) many variations.

By the way, the zero bar is not the first one. It is zero, i.e. it is not there yet.

 
goodnight! I suddenly found a bunch of folders on my C drive and some kind of C++, decided to install, and it's asking me something!!! I'm not good at English, no, I vaguely understood that either the original in the sense of some original version, or something there my computer and did not install for some reason ... In short, it is not clear.

Select one of the options:

Repair - "repair"/restore Visual C++ 2008

Uninstall - remove Visual C++ 2008 from your computer

It makes no sense to normalize the double values to compare them since the two values 1.778946 and 1.778949 will be equal after normalization and this is incorrect since the first value is smaller than the second one.

Normalize double is only needed to send a command to the Dealer, but not for "internal consumption" - comparison of the two values.

 
Got it!!! Thanks a lot!!!!Good thing you asked!!!
