FrameNext not able to retrieve previous frames inserted with FrameAdd

[afusetti]

Hello, my target is to save from Expert Advisors two different sets of information in order to work with that data offline.

To do that, I used FrameAdd to save the data. Having two different arrays I used two different IDs:

FrameAdd("Stati",4,(double)dati_rep.numperiodi, dati_rep.datiperiodi);
FrameAdd("Stati",7,(double)dati_rep.numopdett,dati_rep.listaop);

I noticed that later I was not able to retrieve part of the data I previously saved with FrameAdd. To debug, I took example from Alain Verleyen's code:

if(!FrameNext(pass,name,id,value,data))
      printf("Error #%i with FrameNext",GetLastError());
   else
      printf("%s : new frame pass:%llu name:%s id:%lli value:%f",__FUNCTION__,pass,name,id,value);

It works fine for the first data sets - from a certain point in advance I see the following:

2019.07.04 15:55:06.555 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:1508 name:Stati id:4 value:25.000000
2019.07.04 15:55:09.719 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:1508 name:Stati id:7 value:67.000000
2019.07.04 15:55:12.914 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:2216 name:Stati id:4 value:25.000000
2019.07.04 15:55:16.157 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:2216 name:Stati id:7 value:107.000000
2019.07.04 15:55:19.515 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:74 name:Stati id:4 value:25.000000
2019.07.04 15:55:22.953 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:74 name:Stati id:7 value:90.000000
2019.07.04 15:55:25.282 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:0 name: id:0 value:0.000000
2019.07.04 15:55:25.306 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:0 name: id:0 value:0.000000
2019.07.04 15:55:25.306 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:0 name: id:0 value:0.000000
2019.07.04 15:55:25.348 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:0 name: id:0 value:0.000000
2019.07.04 15:55:25.349 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:0 name: id:0 value:0.000000
2019.07.04 15:55:25.521 FusoNewConf (EURUSD,H1) OnTesterPass : new frame pass:0 name: id:0 value:0.000000

So I am not able to retrieve part of the data I previously saved with FrameAdd. 

What I checked so far is that neither FrameAdd nor FrameNext return errors.

I noticed also that file FusoNewConf.EURUSD.H1.0.mqd (where the frames are saved) grew up to 5 GB.

Any clue please? Did I save too many data? Are there any constrains I'm not aware?

Thank you in advance

You need to use a loop :

while(FrameNext(pass,name,id,value,data))
{
  ...
  printf("%s : new frame pass:%llu name:%s id:%lli value:%f",__FUNCTION__,pass,name,id,value);
}

if(_LastError!=0) printf("Error #%i with FrameNext",GetLastError());

For anyone who can't get their Frameadd/Framenext code to work or output print statements in OnTesterPass() then make sure you don't have to many chart windows open.  I couldn't get anything to output until  I cleared all the open charts using Alt-W.

Now it works as intended.
