stochastic rsi codes

Kutluhan Yesilkaya  
If the stochastic risk line crosses 20 up, buy. If it cuts 80 down, sell. How can I write these codes?

You have only four choices:

  1. Search for it (CodeBase or Market). Do you expect us to do your research for you?

  2. Beg at:

  3. MT4: Learn to code it.
    MT5: Begin learning to code it.

    If you don't learn MQL4/5, there is no common language for us to communicate. If we tell you what you need, you can't code it. If we give you the code, you don't know how to integrate it into your code.

  4. Or pay (Freelance) someone to code it. Top of every page is the link Freelance.

We're not going to code it for you (although it could happen if you are lucky or the problem is interesting.) We are willing to help you when you post your attempt (using CODE button) and state the nature of your problem.
