Have you tried making it a separate function to search for the presence/absence of items?

For example:

Magic - magic number of EA (set in settings, or generated by EA automatically). Then to check the absence of position Buy by current symbol should be written:

Note - not just a command to open a Buy order, but a full function with handling all order opening parameters and errors returned by the server.

However, the tester may do without checking the entered parameters for valid values...



Could you please show this function in full as ready-to-use working code with start function and all descriptions? And better yet, Magic is generated by the EA automatically, i.e. as I understand it, this is the case at the very bottom.

bool ExistPositions(string sy="", int op=-1, int mn=-1) {
   if (sy=="") sy=Symbol();
   for (int i=0; i<OrdersTotal(); i++) {
      if (OrderSelect(i, SELECT_BY_POS)) {
         if (OrderMagicNumber()!=mn)   continue;
         if (OrderSymbol()!=sy)        continue;
         if (OrderType()>1)            continue;
         if (op<0 || OrderType()==op)  
            return(True);
         }
      }
   return(False);
}

if (!ExistPositions(Symbol(), OP_BUY, Magic)) {
   // ... Тут код для вызова функции открытия позиций ... 
   }

Magic cannot be generated, if your computer hangs up (power failure, cat steps on the keyboard, ...), at a new start the EA will lose order control (if it does not write magiks to a file).

It depends on how to generate. My EA is generated using symbol, tf and it's not going anywhere but normally picking up at restart. Picked it up once somewhere and have been using it ever since.

Can I see an example of how it...

Interesting, cite the code please.
 

Hi all, again...)

How do I make objects (any objects) show up on the chart in the foreground and NOT behind the candlesticks...? is there a function for this?

There are no layers on the chart (imho), I switch to show bars but not candlesticks, you can get used to it with time.

I see, thanks...

 
Also, how do I remove the script from the chart?
 

Well, here's a rough one. Took it from ikatsko's advisor. Maybe he's the author, maybe not, the style looks like KimIV... I don't know, but I like it, I'm using it now.
