array out of range in 'MySc.mq4' (505,14)

[MatlabCoder98]

i write a code to scan some indicators in definite time frame and i define some functions 

in a function i want to compare stochastic index for some shift time 

void twoColumn(string symbolName,int x,int y,string text,int fontSize=8,string fontName="Calibri")

{

   double Stochastic[];  

   int limit; 

   int counted_bars=IndicatorCounted();

   if(counted_bars<0) counted_bars=0;

   if(counted_bars<1) limit=Bars-1;

   else limit=Bars-counted_bars;

   for(int i=0; i<limit; i++)

   {

    Print(IntegerToString(i)+" x");

   Stochastic[i]=iStochastic(symbolName, MATimeframe, 14, 4, 4, MODE_SMA, 0, MODE_MAIN, i);   

   string tooltip=symbolName+".: "+GetPeriodStr(MATimeframe)+"\n Stoch :"+DoubleToStr(Stochastic[i],2)+"\nStoch : "+DoubleToStr(Stochastic[i-5],2);

   DrawLabel("ma_"+symbolName,x,y,DoubleToStr(Stochastic[i-1],1)+"    "+DoubleToStr(Stochastic[i-1],1),fontSize,fontName,clrWhite,tooltip);

   }

 }

but it show error in windows and stop running when i change time frame

what is my errors and how can solve it  ?

   Your array has no size, therefor array exceeded. Perhaps it should be a buffer.

You can do :

void twoColumn(string symbolName,int x,int y,string text,int fontSize=8,string fontName="Calibri")

{

   double Stochastic[];  

   int limit; 

   int counted_bars=IndicatorCounted();

   if(counted_bars<0) counted_bars=0;

   if(counted_bars<1) limit=Bars-1;

   else limit=Bars-counted_bars;

   ArrayResize(Stochastic,limit);

   for(int i=0; i<limit; i++)

   {

    Print(IntegerToString(i)+" x");

   Stochastic[i]=iStochastic(symbolName, MATimeframe, 14, 4, 4, MODE_SMA, 0, MODE_MAIN, i);   

   string tooltip=symbolName+".: "+GetPeriodStr(MATimeframe)+"\n Stoch :"+DoubleToStr(Stochastic[i],2)+"\nStoch : "+DoubleToStr(Stochastic[i-5],2);

   DrawLabel("ma_"+symbolName,x,y,DoubleToStr(Stochastic[i-1],1)+"    "+DoubleToStr(Stochastic[i-1],1),fontSize,fontName,clrWhite,tooltip);

   }

 }

You can do :

thank you

but it does not work and show errors again

Where are errors ? Have you try to debug step by step ? Coding and debugging is an art :-)

THANK FOR replying.

it show same error as past errors.

MySc EURUSD,H1: array out of range in 'MySc.mq4' (638,139)

i have a critical challenge and problem in working with arrAY in mql4.

and debug step by step does not help me to solve it.

i think that i should add a forgotten command or function to donot permit to exeed size of array. but i donot know what command i should add ?

It tells you to look on line 505 cursor position 14.( line 638, pos 139 on the next one)

That is the exact location of the error.

Also this:

DoubleToStr(Stochastic[i-1],1)

If i == 0 and you do i-1 then that is -1 and that array location does not exist.
