angevoyageur: The bars from 897 to 2 are never calculated. I don't see how this is an answer to the OP.
So it needs to be fixed so next tick it does 897 to 797, etc.
   int iBar = rates_total - 1 - indicator_counted,
       iEnd = iBar - MAXCHUNK; if(iEnd < 0) iEnd = 0;
   for(; iBar >= iEnd iBar--){
      Buffer[iBar] = ...;
   }
   return(rates_total - 1 - iEnd); // ?
Never said I tested it. :)
 
WHRoeder:

False. On a disconnect/reconnect, only Bars changes, the old IndicatorCounted() doesn't, so it only processes the new bars. Only on older history download would IndicatorCounted return zero. Same for the new prev_calculated: "if since the last call of OnCalculate() price data has changed (a deeper history downloaded or history blanks filled), the value of the input parameter prev_calculated will be set to zero by the terminal."


No, my previous post was correct I have previously tested for this undocumented behaviour, because it caused me some issues.

Bars is never reset to zero. IndicatorCounted() resets to zero but not immediately on reconnect, it will return its previous value for two ticks, then it will return its previous value+1 for two more ticks, then it will reset to zero ... I didn't entirely figure out the reasons for these behaviours, you can see from the logs what it does:


2014.02.20 15:32:16 IndicatorCounted EURUSD,M1: Alert: IndicatorCounted == 250035 //---- Several more ticks after this one will continue arriving in rapid succession
2014.02.20 15:32:16 IndicatorCounted EURUSD,M1: Alert: IndicatorCounted == 250035 //---- Notice these ticks have been arriving in rapid succession (probably artificial)

2014.02.20 15:32:16 IndicatorCounted EURUSD,M1: Alert: IndicatorCounted == 250028 //---- 3rd tick IndicatorCounted() returns the old value+1

2014.02.20 15:32:16 IndicatorCounted EURUSD,M1: Alert: IndicatorCounted == 250027 //---- 1st tick: IndicatorCounted() returns old value again.
2014.02.20 15:32:15 IndicatorCounted EURUSD,M1: Alert: IndicatorCounted == 250027 //---- Internet Resonnected several bars later. IndicatorCounted returns old value (as before disconnect).

SDC: No, my previous post was correct I have previously tested for this undocumented behaviour, because it caused me some issues. Bars is never reset to zero.
  1. No, both are posts were correct. I stated that IndicatorCounted didn't change, and your log shows that I was correct. It also shows that afterwards you get a zero and you are correct.
  2. I never said Bars resets to zero.
  3. Now someone (you) needs to see if the new OnCalculate has the same problem.
 

I was planning to lol ... I'll start a new thread I might copy that IndicatorCounted test to it too.

 

I didnt start a new thread because it is mentioned in the docs that prev_calculated also resets to zero when chart history is added, it does very similar to IndicatorCounted().

You can see rates_previous operates almost identical to IndicatorCounted()

prev_counted == IndicatorCounted() - 1 except on inital zero and history added, then prev_calculated == IndicatorCounted().

Internet disconnect causes identical behaviour.
