1. When you post code please use the CODE button (Alt-S)! (For large amounts of code, attach it.) Please edit your (original) post.
             General rules and best pratices of the Forum. - General - MQL5 programming forum
             Messages Editor

2. What happened?

3. That's nice.

4. Help you with what? You haven't stated a problem, you stated a want. Show us your attempt (using CODE button) and state the nature of your problem.
             No free help
             urgent help.

5. Your stochastics() function is never called in OnCalculate().

6. double  StocSlow;
   double  StocFast;
   double  StocSlow1;
   double  StocFast1;
   void stochastics(){
      double  StocSlow=
      double  StocFast=
      double  StocSlow1=
      double  StocFast1=

   Fix your warnings.

Do you want to run this as indicator or as expert advisor? You need to make up your mind. And depending on this, you have either OnCalculate() or OnTick() function to define. Also, OnInit() should be defined, it is missing in your code.

Before you want to write a code you should study the MQL language, Help and mql samples to see how it works, what are the basics etc.
