   limit=rates_total-prev_calculated;

      limit++;
Taken from the MACD example supplied with the terminal.

Thank you, but in this case limit=0 and in the loop the calculation is from the last bar to zero

Thank you, but in this case limit=0 and in the loop the calculation goes from the last bar to zero

In that case, if 0 is counted, we take all the bars, and in other cases, we take as many bars as are not counted:

  limit=rates_total-prev_calculated;
  if(prev_calculated<1) limit=rates_total-1;

Then, if 0 is counted, we take all bars, in other cases, how many are not counted:

Thank you very much! I dont understand why it works, when I loadrates_total and prev_calculated are equal to equal number of bars and then limit = 0, further the condition which is not true, why it works ? Explain it to me please,

I want to understand why it works ...

When loadingrates_total=Bars, a prev_calculated=0.

When loadingrates_total=Bars, a prev_calculated=0.

Oh that's right, I just didn't look closely at the log, first tickprev_calculated=0. thanks again!!!!

You can. Just leave more space for it, folders of history and logs are growing, I have more than 5 Gb of history, and once my Expert Advisor had 20 Gb of errors in its logs, it's good that it's not on a flash drive ))))
Right. I see. Thank you all!
 

Hi all. I want to use data from H4 in strategy tester on H1 timeframe. When I initialize the indicator it is rendered correctly, but when I start the tester it is not redrawn.

Is this a feature of the tester? How can I overcome it?

int shift = iBarShift(Symbol(), PERIOD_H4, Time[i]);

bufBuffer[i] = iClose(Symbol(),PERIOD_H4,shift);

Yes, the tester blocks access to data of other TFs in the visualization mode. In normal testing without visualization, the data goes properly, but rendering suffers.

There is no way to solve this problem directly - we can only complicate the algorithm and draw objects, but is it worth it?

 
Good afternoon, 5 kopeck question))) Can you please tell me what the "&" sign means when passing to a function? Example: int determineSection_D1(int & askSection_D1,int & bidSection_D1) ? Thank you.
