Size of struct

[Ingvar Engelbrecht]

 Working on class to send trade information from a MT5 EA to an MT4(Latest) EA using named pipes.

 I am using the tick server example as a guidance. So I am planning to use a struct like this to send the info:

 struct TradeInfo
 {
   string symbol;
   datetime  timestamp;
   double price;
   double TP;
   double SL:
   double size;
 }

To use this I need to supply the length of the struct. How do I calculate that?

Can you edit your message please.

  That is simple  :-)

  Thanks.

  Since one of the variables is string and the size is calculated at compilation time it seems proper to prime the string

  with a symbol name before getting the length by "sizeof"
