You should remove the extra semicolon ...

void OnStart() // <- remove the ";"
{

Also, please edit your post (don't create a new post) and replace your code properly (with "</>" or Alt-S), or attach the original file directly with the "+ Attach file" button below the text box.

Thankyou! I removed it and now have 10 errors instead of the one.

 😅 That is to be expected of a newbie coder that still does not know their way around the language and the platform. It's part of the learning experience.

Also, please fix your post as I demonstrated in the animation. Copy the code from your original code file and not from the post itself.

Is this supposed to be MQL4 or MQL5?

Please edit your post and use the code button (Alt+S) when pasting code.

EDIT your original post, please do not just post the code correctly in a new post.

MQL5

(Alt+S) did not work with my Mac. Hope that works and I appreciate the help.

MQL5

Well this appears to be MQL4

 // Open a buy order
   int order = OrderSend(_Symbol, OP_BUY, volume, Ask, 3, sl,
   tp, "My gold trade", 12345, 0, Green);
   
   
   // Check if the order was successfully placed
   if (order > 0)
   
   Print("Buy order placed successfully, ID: ", order);
   else
   
   Print("Error placing buy order:"),
   ErrorDescription(GetLastError()));

I'm sure that must be the problem Keith. Thanks! Is there an easier way to convert it to MQL5?

Yes, in the short-term, but in the long-term you will end up not learning MQL5 properly, making it much more difficult to progress.
