Last 15 minutes of TICK data maintained in array - How can I do it?

[xazarlx20]

The main problem I have is figuring out how many ticks there are before resizing the array.

int duration=900; //15 minutes

Do

{

    for (int i=arraySize-1; i>1; i--)

    {

     array[i]=array[i-1];

    } 

}

while(currentTickTime < firstTickTime  + duration )

I am just stumped!!!

2.  for (int i=arraySize-1; i>1; i--) array[i]=array[i-1];

   No need to keep moving values and then updating array[0] (which your code doesn't do), just add the last to the enlarged array.

   Perhaps you should read the manual. ArraySize/ArrayResize. You start with zero size, enlarge it by one for each tick. The size of the array is “how many ticks there are before.”

EDIT your original post, please do not just post the code properly in a new post.

SymbolInfoTick(_Symbol,currentTick);
int i=ArraySize(ticks);
while(--i > 0 && ticks[i].time + duration < currentTick.time);
ArrayResize(++i + 1);
while(--i >= 0)
  {
   ticks[i+1]=ticks[i];
  }
ticks[0]=currentTick;

Assuming you need an array of tick structs ordered newest first.

Moving ticks up is unnecessary, even if you want that.

int i=ArraySize(ticks);
ArraySetAsSeries(ticks,false);
ArrayResize(ticks, i + 1);
ArraySetAsSeries(ticks,true);
ticks[0]=…;
