Dynamic Array : array out of range

[Icham Aidibe]

Hi, here's a code :

   double ArrayHigh[];
   double ArrayLow[];
   CopyHigh(Symbol(),TStf,0,N,ArrayHigh);
   CopyLow(Symbol(),TStf,0,N,ArrayLow);
   double LastHeight=0;
   double LastPrice=SymbolInfoDouble(Symbol(),SYMBOL_LAST);
   for(int i=0; i<N; i++) LastHeight=LastHeight+ArrayHigh[i]-ArrayLow[i];
//--- calculating the average size of the last N bars
   LastHeight=LastHeight/N;

With the error I running a test :

2014.10.29 14:08:54     MQL5 Cloud Europe       genetic pass (0, 275) tested with error "critical runtime error 502 in OnTick function (array out of range,  line 721, col 58)" in 16 ms (PR 177)

Any help would be very appreciate !

CopyHigh and CopyLow can return less than N value. You have to check the returned value of both functions.

What's the limitation ? Since I'm trying to optimize ...

Try to use something like this:

(if you need at least "N" bars then you should skip these results)

int limit=MathMin(N,ArraySize(ArrayHigh));

for(int i=0; i<limit; i++)

Great ! thanks Lost ! I don't need to do it also with arraylow, supposing it should be the same thing ... right ?

Yes, it should be the same but you can do the this:

int limit=MathMin(N,MathMin(ArraySize(ArrayHigh),ArraySize(ArrayLow)));
