As far as I understand accrual, as in the demo or in the tester...
what's that? Re-accrual or accrual
 
Dmitriy2:

So when outputting values to the log, only once (for the first time) the parabolic function, i.e. CopyBuffer, returns 0 and not -1, as it should be in case of error (although it shouldn't be either, all data is there, all downloaded, no great multidimensional arrays, no error should occur!) And this happens ONLY in the tester and ONLY ONE time. From here on everything works fine.

In basic code I don't care what the functions return, eventually when it comes to a trade request, the values received for the request are checked by the universal function, and if everything is OK we send the request, if not - we wait for it to be OK...

Try the following code in your function of getting parabolic value.

double Параболик(ENUM_TIMEFRAMES период,double step,double maximum,int бар)
  {
   double ЗначениеParabolic[1];
   int Parabolic=iSAR(Symbol(),период,step,maximum);
   int cb=CopyBuffer(Parabolic,0,бар,1,ЗначениеParabolic);
   if(cb!=1) Print("BarsCalculated ",BarsCalculated(Parabolic),", CopyBuffer ", cb, ", ArrayValue ",ЗначениеParabolic[0]);
   return(ЗначениеParabolic[0]);
  }

You'll get something like this in the log

2010.09.15 14:53:53     Core 1  2010.09.01 00:00:07   BarsCalculated -1, CopyBuffer -1, ArrayValue 0
2010.09.15 14:53:53     Core 1  2010.09.01 00:00:07   BarsCalculated -1, CopyBuffer -1, ArrayValue 0
2010.09.15 14:53:53     Core 1  2010.09.01 00:00:07   BarsCalculated -1, CopyBuffer -1, ArrayValue 0
2010.09.15 14:53:53     Core 1  2010.09.01 00:00:07   BarsCalculated -1, CopyBuffer -1, ArrayValue 0
2010.09.15 14:53:53     Core 1  2010.09.01 00:00:07   BarsCalculated -1, CopyBuffer -1, ArrayValue 0
2010.09.15 14:53:53     Core 1    SLпоПервойТочкеПараболика=true

It will explain why you get 0 and not -1.

I'll repeat it for the 3rd time. The data is there, but the indicator values at that moment MAY not yet be calculated. It is written about it in the help!

Try this code in your function to get the value of the parabolic.

You will get roughly this output in the log

This will explain why you get 0 and not -1.

I will repeat it for the 3rd time. The data exists, but the indicator values at that moment MAY not have been calculated yet. It's written in the help!

Exactly, we're getting the parabolic value, not the CopyBuffer response...

ok... change the parabolic function to the one you provided (with the prints).

I add the prints in the for loop (it has no zero protection)

if(НапрСигнала==ORDER_TYPE_BUY)
     {
      if(SLпоПервойТочкеПараболика==true)
         for(i=0;;i=i+1)
           {
            Print("бай, параболик до иф ",Параболик(PERIOD_CURRENT,0.02,0.2,i+1));
            if(iLow(PERIOD_CURRENT,i+1,1)<Параболик(PERIOD_CURRENT,0.02,0.2,i+1))// || Параболик(PERIOD_CURRENT,0.02,0.2,i+1)<=0
              {
               Print("бай, параболик после иф ",Параболик(PERIOD_CURRENT,0.02,0.2,i+1));
               break;
              }
           }
      ЗначениеSAR=NormalizeDouble(Параболик(PERIOD_CURRENT,0.02,0.2,i)/ТИК,0)*ТИК;
      if(БИД>ЗначениеSAR) //bay
         slтики=(int)NormalizeDouble((АСК-ЗначениеSAR)/ТИК,0);
     }
   if(НапрСигнала==ORDER_TYPE_SELL)
     {
      if(SLпоПервойТочкеПараболика==true)
         for(i=0;;i=i+1)
           {
            Print("селл, параболик до иф ",Параболик(PERIOD_CURRENT,0.02,0.2,i+1));
            if(iHigh(PERIOD_CURRENT,i+1,1)>Параболик(PERIOD_CURRENT,0.02,0.2,i+1))// || Параболик(PERIOD_CURRENT,0.02,0.2,i+1)<=0
              {
               Print("селл, параболик после иф ",Параболик(PERIOD_CURRENT,0.02,0.2,i+1));
               break;
              }
           }
      ЗначениеSAR=NormalizeDouble(Параболик(PERIOD_CURRENT,0.02,0.2,i)/ТИК,0)*ТИК;
      if(БИД<ЗначениеSAR) //sell
         slтики=(int)NormalizeDouble((ЗначениеSAR-БИД)/ТИК,0);
     }

no errors in the journal

look at the picture in the Experts tab; no error messages as well

you can count parabolic points, everything coincides well, on the twelfth one, exit the cycle...

 

I realised a long time ago that in MQL5 at "that moment" or at that... The data here or there may not be calculated... But it's not right, you have to fix it, not to write crutches in the code

by the way, it's the same with all other indicators, not only with parabolic

 
maryan.dirtyn:
i don't know what fc is. i just need to know HOW it will be at the championships.

FC - Forex Club and say its terminal Rumus2.

Do you have a test account for the championship? Try it and everything will be clear...

I will never believe that MQL5 and MQL4 were written by the same team.(((

MQ4 - flying...

This topic has been discussed more than once. It was revisited not too long ago(https://www.mql5.com/ru/forum/1951)

I haven't seen this thread... same thing...

The point is that I'm not going to stupidly make checks on every line for all occasions, confusing and cluttering up the code. If that's out of the question then... crutches are added, a big enough project is finally completely redone and working...

And in general, I'm just amazed at this approach... It turns out that not the first time such a question arises (and I'm sure more than once in the future will arise in other people), and every time "for the first time" to spend a lot of your and others' work time to explain what you need to do to bypass this bug ...

The only thing to do is to add into TESTER that recommended in that thread only ONE Sleep(1000) at start of Expert Advisor.

It must not be so that the shell would imply glitches, and those glitches must be avoided in the code. And the TERMINAL is working correctly and correctly, there are NO ERRORS (in this situation). But the operation of the tester is DIFFERENT from that of the terminal.
