Oh you again. You're the guy with a lot of ideas. You should know we can't help you with only partial code

:)

 

yea, is me ...

please help me to done my first work...


why the global scope not allowed ??

 
can i just copy and paste and just change some word to make it ?
 

I think RaptorUK told you not just to copy paste and should learning first. But still, you learning by copy pasting without any idea how things work. Would you please be so kind to read the book first (click here) before even asking a question here in the forum.

For a starter, you writing the code in deinit() which will never get executed !!!

Not literaly copy paste, but yes if you know how it works and do it in the right way. I did/do that too.
 

ok...

i learning from there, then ask again next week...

This is the end of deinit(), and still you write the code outside deinit(), and that's why you get [expression on global scope not allowed]

   return(0);
  } ?? <<======================= the end of deinit()
//---- minimums counting
   a=Bars-KPeriod;
 

I see no sense making it the separate indicators are giving same value as put togheter if it is rvi on stochastic or stochastic on rvi

It just make no difference.....

 

i just try to combine it,

just for practice.....
