array out of range

[texoro]

The code excerpt from where the error is this

 

   for (i = Bars; i >= 0; i--) {

      TrendUp[i] = EMPTY_VALUE;

      TrendDown[i] = EMPTY_VALUE;

      atr = iATR(NULL, 0, 10, i);

      medianPrice = (High[i]+Low[i])/2;

      up[i]=medianPrice+(Multiplier*atr);

      dn[i]=medianPrice-(Multiplier*atr);

      trend[i]=1;

The lines which gives the error are these

      TrendUp[i] = EMPTY_VALUE;

      TrendDown[i] = EMPTY_VALUE;"

 

Do you think why? then one thing is strange if I do run into a mql file with only the function code nn problems if I put it in a file with other code gives me the problem

I hope for an answer

Have you checked the your access to your array, the size of the array?

PLS use the SRC-button if you post code!

2. for (i = Bars; i >= 0; i--) {
         TrendUp[i] = EMPTY_VALUE;

   Assuming TrendUp is a buffer it's size is always Bars. That means the index is [Bars-1 .. 0], [Bars] does not exist, array out of range.
3. Your lookback is 10 (iATR(NULL,0, 10, i) Do your lookbacks correctly.
