Greetings All ! Thank you all in advance !

Bug of this type:

There is a line Low_D1_Level relative to which we are looking in arrayBar_data_D1 [][6]; new levelMin_D_Level

//---global variables

double_D1_Level;

double Bar_data_D1 [][6]; //copies bar data of the specified chart into the array and returns number of copied D1 bars

The first dimension of the array contains the number of bars. The second dimension has 6 elements with the values:

0 - time,
1 - open price,
2 - lowest price (low),
3 - highest price (high),
4 - close price (close),
5 - volume.

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

void Level() 
ArrayCopyRates(Bar_data_D1,_Symbol,PERIOD_D1); // Копирует в массив данные баров указанного графика и возвращает 
Low_D1_Level   = iLow (_Symbol,PERIOD_D1,1);   // Возвращает значение минимальной цены бара  D1

Please help.

I've tried everything and still get error 130.

Everything works for me, no errors

[Dark Kchlyzov]

In the strategy tester, run from 2016.12.15.

2016.12.16

Run the optimisation. Optimisation is interrupted by a CriticalError message

from the fact sheet

Dark Kchlyzov:

I don't understand, where does the loop end?

for(int i = 1; 0 <= Bar_data_D1 [i][2] ;i++)

It's supposed to be the last element of the array. No?

And then do a check for inequality

for(int i = 0; i<ArrayRange(Bar_data_D1,0) ;i++)
   {
   if(Bar_data_D1 [i][2]>=0)
      {
      
      }
   }

Then there will be no surprises of going outside the array

[Tretyakov Rostyslav]

Aliaksei Karalkou:

Start the optimisation. Optimisation is interrupted by the message CriticalError

No errors, with optimisation from 01.12.2016 to today

Okay, I got it. I'll try it right now.

Thank you!
