mt4 script

 
Respect to everyone. There is an mq4 script, can I write new things in it and use it in the mt4 terminal? I'm new to this, can someone explain me how to do this script?
 

It's possible to make any kind of indicator, of course

  1. Trend: Respect to everyone.

    Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?

    Next time, post in the correct place. I have moved this thread.

  2. Trend: There is an mq4 script,

    There are numerous scripts, EAs and indicators, in the codebase and market.

  3. Trend: can I write new things in it and use it in the mt4 terminal?

    Do you know how to code in MT4?

  4. Trend: I'm new to this,

    What is “this?;”

  5. Trend: can someone explain me how to do this script?

    What script?

You have only four choices:

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

  2. Try asking 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.

Hi

If you have the code of the script you can modify it as you wish and use it later in mt4. You can access the code when you simply open the mq4 file of the script (not ex4) which is in your Experts/Scripts folder on your data folder of the platform. it should open in the meta editor program and you can code your own functions within. When you are done click „Compile” button at the top of the editor and from now on this file would work as you coded it and you can use it on the platform.
Of course you need to know how to code in mql4 a bit to make the changes (use the recommended links to learn how to code). Or you can find a freelancer to code this for you.
