Kalenzo:
Well i think you are complicating things too much. Try using few shorter parts of code instead of one big function. This should give you some hint:

Thank you for your help. I tried to add the code you said, but to tell you honestly I am lost. After I added the code, the EA is showing a slue of problems. I have been going through the syntax but but I am lost.

I also had a question about using functions inside the int start() function. Is that allowed? Isn't the vairables initialized within a function unable able to be seen by other functions?

So

int start()

{

function( int x)

{

// Do something

return(x)

}

// Do Something ... "Can x be called in the start() function?'

return0;

}

Ive attached my EA source. Your help is very much appreciated.

Limstylz:
Hi All,

I originally posted this as a new thread, but it was moved into another programming thread (I have no objections to its move BTW) and now seems to have got lost due to the amount of posters in that thread.

Perhaps someone here can help me?

Limstylz take a look at this Ask! thread page 39. I think there might be some information that might help you. Good luck

 

Cheers buddy...

Thanks cutzpr, but I managed to sort it out already... bloody internet connection was down all day and I had to use my own brain cells for once

Anyway, to answer your question about the int start ()... This is your main body of the EA and is updated continuously, every tick (I think thats right).

Your code is a little discombobulating... can you explain where you are experiencing an issue? I might be able to help if you can break down the problems, although I'm really just only learning MQL4 myself.

 

what`s wrong with this?

Could someone here help me,if i copy this indicator to my meta,i need more than 5 minutes just to open my meta.But when i deleted it,and i reopen my meta, it become normal again.

Thanks!!!it'great!

Embeded custom indicator into expert advisor

Hi folks, anyone know how to add the custom indicator below into an expert advisor ? So that we no need use the icustom to call it from the file ?

You must use the iCustom function in your EA to call this indicator:

iCustom(Symbol(),0,"ARSI",ARSIPeriod,0,0);

The number in red is the bar you want to look at. Change it as you need.

Thanks for your reply. Ya, i know that we can use the icustom function, but as i know, we can embed the indicator function by input the coding from the indicator, the following website Indicators embedding in Expert Advisors (iCustom alternative) | www.metatrader.info that explained by codersguru describe about that, but for the ARSI indicator, i not sure how to embed it into an expert advisor. Thanks for any recommendation !!

 

improvement of 10points3

Hi everyone.

We are trying to improve 10points3. We need to change the code to close last third trade. Please refer to the last posts here:

https://www.mql5.com/en/forum/174975/page259.

We are getting good results here.
