Questions from Beginners MQL5 MT5 MetaTrader 5 - page 1233

Any advice - I'm doing forward optimisation, but for some reason there are no 2 options by criterion in the optimisation results. as I understand, there should be back and forward data. there's nothing similar in the context menu either. how can I see back and forward data from the optimisation results?

A word of advice to a beginner.

When a Start event occurs in the script, it is handled by the OnStatr() function.

I have written a script called Print_1.

void OnStart()
  {
   int x, y, z;
   x=5;
   y=4;
   z=x+y;
   printf(IntegerToString(z));
  }

I think this function should print to terminal log number 9 when user clicks on Print_1 script. But nothing happens.

How and where in the terminal to see output z on the screen? What is the source of the Start event? How to start it so that number 9 finally appears on the screen? And run it from the terminal.

How can I track the moment when an order triggers in order to place another order in the same direction and at a certain distance? (on mql5)

Print and printf print the information to the "Toolbox" window, to the "Experts" tab.

Print	Prints a message into the journal
PrintFormat	Formats and prints the sets of characters and values into a log file according to a preset format

I've heard it's not a good idea to doOnTradeTransaction, as it doesn't always work

If a hedge account, is it possible to track the triggering of an order by changing the number of orders?

New problem, need to select the last open position in the hedge

Sysmart:
New problem, you need to select the last open position in the hedge

OnTradeTransaction+ variable declared in EA header. The variable stores the type of the last position opened. It is of long type and initialized with value '-1'. In OnTradeTransaction, you catch the moment when a position was opened and write it into the variable.

Then you check this variable in your code - if it is equal to '-1', then go through the loop and compare the time when each position was opened. Find the 'youngest' position andwrite it into the variable. If the variable is not equal to '-1' - then you compare it with the position type.
