how to capture a list in a bool flag trap

[PaulMohn]

Chelsea seems to be out of the office today so I post in general thread this question

I succeeded to trap an int in bool flags (x1 and x2 below) but I've a hard time doing the same with orders from sublists.

I'm trying your method with several lists, as it seems simpler,
since I've just found out about the
.Except()
or .Intersect() uses:

I'm testing using 2 Sublists, y1 and y2.
I set it so y1 captures the orders of the 1st Entry group (with a incrementer and a bool doOnce...).
but the problem is y1 doesn't just capture the 1st Entry Group, instead it keeps adding the new Entry orders.

I don't know how to get the capture working and can't find an answer online.
I suspect the problem comes from my State.DataLoaded instances of y1 and y2. But I don't know why.
Is it the syntax that is wrong? Is y1 = new List<Order>(); telling to keep adding the 2nd Entry orders to y1 inspite the condition
if (doOncelistCount1stOrdersGroup && (LongEntriesCounter == 1)). Why?


Why does the list keep incrementing despite the incrementer and a bool doOnce?
y1

y1 = submitTargetsOrdersList; 

should only capture the orders present in the list at the time the Numpad.Multiply is pressed for the 1st time.
Then,

y2 = submitTargetsOrdersList.Except(y1).ToList(); 

y2 should just Except the previous orders of the "superlist" (submitTargetsOrdersList), leaving only the 2nd Entries orders in y2.

I tested printing the count (y1.Count) on 2 entries (1st 2 orders/contracts, 2nd 3 orders/ contracts).
and it does prints 2 on the 1st entry, but then it prints 5 on the 2nd entry.

x1 : 2
x2 : 0
Buy
NP7. y1.Count : 2
x1 : 2
x2 : 3
Buy
NP7. y1.Count : 5
NP8. y1.Count : 5
NP8. y2.Count : 0
Error on triggering custom event for NinjaScript 'ProfitSnipers' on bar 5022: You are accessing an index with a value that is invalid since it is out-of-range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

I need it to print 3 on the 2nd entry not 5.
What am I missing to get the y1 list to capture only the 1st entry orders count? Thanks!

Below the reduced relevant snippets (if it's clearer also the script is attached):

{

   y1 = new List<Order>();
   y2 = new List<Order>();

      {

       y2 = submitTargetsOrdersList.Except(y1).ToList();


       doOncelistCount2ndOrdersGroup = false;

       {
         Print("NP7. y1.Count : " + y1.Count);


        for (int index = 0; index < Orders1stGroupQty; index++)
        {
         currentPTPrice = y1[index].LimitPrice + (ProfitTargetMove * TickSize);
