where can get this code ?

 
when set up a new mt4 terminal ,the orignal charts have "BUY "/"SELL" on it ,but i can not get the code from the script fold ,where are they ?
 
You mean the small order window? There's no script for that. You just click the triangle next to the symbol name (top left corner).
 
yes, thanks .  but  i  want to add buylimit/selllimit/buystop/sellstop  function to it , may we do it ?
 

I can't answer your question, but you already have some right-click options:
