How do I get credits or how do I deposit them?

Here is the code for Expert Advisor which uses this indicator TrendToTrend_open

code below

Question - why does my Expert Advisor set this indicator with a close price?

//--- входные параметры
input int LongTrend=14; // Период LongTrend
input int ShortTrend=7; // Период ShortTrend
input int EA_Magic=0;   // Magic Number советника
input double Lot=0.02; // Количество лотов
input double STR= 0.14;
input double TR= 0.1;
input double TP= 0.55;

//--- глобальные переменные

int TrendToTrend;
int TrendToTrendOpen;

//+------------------------------------------------------------------+

     {
      Alert("На графике меньше 60 баров, советник не будет работать!!");
      return(-1);
     }
TrendToTrend=iCustom(_Symbol,0,"TrendToTrend",LongTrend,ShortTrend);
TrendToTrendOpen=iCustom(_Symbol,0,"TrendToTrend_open",LongTrend,ShortTrend);

if(TrendToTrend<0||TrendToTrendOpen<0)

Hello!

Can you please point me in the direction of the answer to your question?

I have an EA with two strategies that open trades on different principles. It has a common position as the end result.

A bit later, I need to understand how each strategy has contributed to the position. So, which strategy (or two) opened the position.

How do I do it?

Thank you!

If your EA has the ability to disable one of the strategies and you can change the magic number in the settings. Then you should add two EAs in your account and disable one of the strategies in each of them and set different magic numbers for positions and then use magic numbers in the history to track which one gives more profit or loss.

Thanks for the reply. I made through static variables that change their value if the strategy position is open (on closing and stop loss the values also change). In general this works fine, but I understand that after restarting the EA it will lose its orders.

Why isn't the money ticking?

The calculation update isn't frequent. Once a day maybe.

thanks, buddy... i'll keep that in mind.

I've got computers in the basement, ...., mining the pots... let's do something.

I don't understand why the function returns 0:

int BarsAmountPassed(datetime open_time)
  {
   datetime time_array[];
   int n;
   Print("inpupt time=",TimeToString(open_time));
   CopyTime(_Symbol,_Period,open_time,TimeCurrent(),time_array);
   n=ArraySize(time_array);
   Print("number of elements in array=",n);
   return(n);
  }

Calling like this for example:

int bars;
bars=BarsAmountPassed(1365198000);  
Print(__FUNCTION__+": Баров прошло с этого времени ",bars);

n writes correct, but returns 0.

Calling it like this for example:

n writes correct, but returns 0.

It is strange, if I change the function type to short or double, it returns the calculated value (it turns out to be 4 in this example). But with int 0.
