How to edit ea.

any one who can help or teach me how to modify EA?i want to add trailing stop to EA.Dont know how to write in.

Here you go, bit of homework for you:

https://www.forexstrategiesresources.com/forex-articles/exit-strategy/expert-advisors-mt4-trailing-stop/

To modify an Ea if you have the MQL file, right click it and click modify. Then write your code, the link above should have some examples of code.

totally dont have knowledge on it.i just want to put trailing stop setting on EA.

Do you have the source code for the EA? If you open the navigator and right click the EA does it ask you if you want to modify it?

If it doesn't then you can't, if it does, then click it and you'll be able to edit it.

A crude way, only problem you need to have account number of client you're selling to. Hard code the account number, compile and only release the .ex4 file.

int accountNo = xxxxxx; // client account number
     
if(AccountNumber() != accountNo) // Checks account number and will only trade if account number matches
    Alert('Your account number does not match!');
else
{
    Code for EA
}

But if someone really wants your code, then they can hack and decompile it, but still a hassle to do.

I can code it (hardcoded MQL4/5) for you or anybody else who needs this for his EA for a low fee (to be prepaid). If you like, msg me for more details.

Warren, you could try this guide out

What is the best way to learn how to be able to write an EA, can someone recommend a methodical method or know someone they would recommend offering tutorials, thanks to all.

If you have studied coding before, you will pick it up fairly quickly, probably like 1 week or so, if you have not, then it might take awhile, but it is not impossible. It is incredibly fun.

You can check out the expert advisors here:
https://www.mql5.com/en/code/mt4/experts

Best way to learn from my experience is to, download the source file and view the source code and play around with that, make changes, see what pops. Find out what each code does, after sometime, it will be like second nature to you.

Once you have a template up and running, you just need to change the buy and sell signals and how the trades are managed and closed. Like example, sometimes you just want to set a trade order with a standard tp or you want a trade's tp level to be hidden from your broker and you just have a function that OrderClose when the TP is met, or you could send a hedging trade to hedge off your current losing trade.

Once you have got a new EA fired up, you can then do your own optimization tests or code it to MT5 to take advantage of the multi threaded capabilities.

From there you could move on to more advanced methods like reading off a dll file, that further expands your capabilities to data mine or scrape off data from other reliable data sources.

Quoted this in another thread, but I'm sure this will be very helpful.

Yea those videos are good too. Giving you an immediate view of how to code.

Easiest way is to leave your EA alone and use this. https://www.forex-tsd.com/metatrader-4/7552-swiss-army-ea-automatic-order-management.html
