[amibroker] Help with Loops

["oceanchimes" <oceanchimes@xxxxxxxxx>]

Hello,
I have been trying to get a loop to work that has only 7 elements.
Method #1
It keeps giving subscript 'out of range',
The 7 elements are overwritten each iteration.

If I use full array size of barcount it works ok. Method #2
A code section is below to illustrate what I am trying to do.

Which is the method to employ? or is there a basic mistake in method#1? 

I suppose I could use non-array  variables for each exit condition,
but more it is easier to code (convenient) to use an array later in
the code to determine sell signal and type

thanks for your help
and the heap of tips from the group in the past

=========================================================
SetOption("InitialEquity", 20000 );
SetTradeDelays(1,1,1,1);
SetOption("MaxOpenPositions", 20);

// simple system...
p1 = 10;
p2 = 22;
MaxNumExit = 7;
// MA crossover
Sell=0;
Buy=Cross( MA(C,p2) , MA(C,p1) );
Buy =ExRem(Buy,Sell);
Sell = ExRem(Sell,Buy);

Filter = Buy OR Sell;
//set up array to Check if exit Conditions(7) are met;
//an array of 7 elements holds the result of each exit condition per
iteration=i
//the exit array is initialised to zero at beginning of exit condition
code
//at end of exit condition code determine if exit signal and exit type
number 

//METHOD #1 - ERROR
in_Trade = 0;
// want to iterate to find exit conditions
for(i=1; i<BarCount; i++)
{
 in_Trade[i] = ( in_trade[i-1] OR (Buy[i] AND !Buy[i-1]) ) AND !Sell[i-1];
 //-BELOW ALWAYS SUBSCRIPT OUT OF RANGE ERROR
 for(k=1; k<=MaxNumExit; k++) { ExitP[k] = 0; } //initialise exit array

// exit condition 1 to 7 here

  for(k=1; k<=MaxNumExit; k++)
  {
   //determine exit type here-SUBSCRIPT OUT OF RANGE
  }
}

//METHOD #2 - OK

in_Trade = 0;
//if change to array size,for all loops
for(i=1; i<BarCount; i++)
{
 in_Trade[i] = ( in_trade[i-1] OR (Buy[i] AND !Buy[i-1]) ) AND !Sell[i-1];
 // NO ERROR
 for(k=1; k<BarCount; k++) { ExitP[k] = 0; } //initialise exit array
 }
