2) There cannot be UPPER and LOWER fractals on the same bar at the same time, respectively, check

belongs to the category of programmer idiocy.


Both fractals can be on the same bar

he meant minutes, but forgot about months
Hello

There is the following line in the code

 if (G_time_344 == Time[0]) return (0);
As I understand it, it is responsible for the EA delaying recalculation until a new bar appears. Until the zero bar open time changes, the recalculation stops.

Accordingly, if I open an EA on minutes, it will be recalculated with every new minute. And if I open it on H4, it will be recalculated every 4 hours.

How to write this line correctly, so that the EA will not take the opening time of the current bar, ie, the bar at which the terminal is open, but the one that I will specify in the settings? That is, I place the EA on H4, for example, and it will recalculate every 5 minutes, because I have set it so. Or every minute.

What's the difference between minutes and months?


evillive:
What is it complaining about in the modification log? "Stupidly opens new pending orders" because there is no limit, but there is an OrderSend.
No errors, just yellow triangles.

I agree, there are nice moments on the M1 as well. but on the months every bar is like that.
No further questions, I've worked it out myself.
TarasBY:

1) Any strategy must be defined by the number of orders open at the same time. Accordingly, before opening the next order, we should check how many are already open.

2) On one bar, there cannot be UPPER and LOWER fractals at the same time, respectively, the check is classified as

belongs to the category of programmer's idiocy.

3) Before writing the conditions for returning buffer indicator values, you need to know exactly what value is "empty" for it? Have you checked that it is 0?

4) The construct.

Although it will work (in most cases), but is unnatural, because it is a "free-will" idea of the developer, and is uninformative for the trader. An alternative - the tracking of a new bar.

5) You have to start from the basics, because this:

The best way to understand is to study how other people's codes work and modify them for your own purposes. Good luck.

I'm trying to write as I've read, looked, understood. Your critique reminds me of an MQL4 manual - I understand it only if somebody explains it to me. 
if(Up>0&&Down==0&&Volume[0]<2)     //если верхний фрактал есть а нижнего нету и прошло не больше 2х тиков то:

      }
    


And this code 

if(Digits==3||Digits==5) {tp=TP*10*Point;sl=SL*10*Point;} // условие для пятизнака
  else if(Digits==2||Digits==4) {tp=TP*Point;sl=SL*Point;} // условие для четырехзнака

it is better to write in init() and better not like this

double   point; // на уровне глобальных переменных

int OnInit()
{
   point = Digits%2 == 0 ? _Point : _Point * 10;
}

and then in start() 

tp = High[3]+TP*point;

I need a buy stop followed by a fractal trailing behind the price and a sell stop with the same procedure.
