Invalid Pointers Access Help!

[Christ Krishna]

Hi community,

I'm so new to all this so please bare with me...

long story short I've got pointer access issues. I'm using Creating Multi-Expert Advisors on the basis of Trading Models - MQL5 Articles as my start point to which I've made little adjustments.

I get this when trying to run my code, which I will provide. The Bot used to run but now at runtime i get this error.

2021.12.11 14:01:51.967 ModelTest2 (AU200,H1) Load indicators...

2021.12.11 14:01:51.967 ModelTest2 (AU200,H1) cannot load indicator 'Moving Average' [4302]

2021.12.11 14:14:13.047 ModelTest2 (XAGUSD.s,M5) cannot load indicator 'Moving Average' [4302]

2021.12.11 14:14:13.047 ModelTest2 (XAGUSD.s,M5) Error creating MACD indicator

2021.12.11 14:14:13.047 ModelTest2 (XAGUSD.s,M5) invalid pointer access in 'ModelTest2.mq5' (112,30)

I'm also pretty sure that the virtual orders don't get added...

bool CModel::Add(ulong Ticket,double stop_loss,double take_profit)
  {
   CTableOrders *t=new CTableOrders;
   if(!t.Add(Ticket,stop_loss,take_profit))
     {
      Print("The order addition has failed. Check order parameters.");
      return(false);
     }
   if(ListTableOrders.Add((t))==-1)
     {
      Print("Can't add order to the orders table. Error!");
      return(false);
     }
   Print("Order ",Ticket," has been added successfully");
   return(true);

Someone please help! 

Update!

Fix first issue, it had to do with symbol suffix for broker I which to having not realized it!

Second isssue still persists… During runtime only the last print statement outputs indicating that in theory something did get added to the list. But elsewhere in the EAs work it doesn’t see it!

Try reading the log. It states the problem.

Elsewhere in model_ma it’s supposed to print the list.total() but prints 0

Maybe you begin with this:

 cannot load indicator 'Moving Average' [4302]

Solved that by adding all symbols to watchlist… total elements still outputs 0

Thank you, I knew this one would come… 

I think my problem is understanding the all object and pointers thing…!
