newdigital,
Sorry for using large size font in previous post.
Sorry for my poor english. I raised previous post as " To Do And Not To Do " with EA with GlobalVariables, I did not mean that I wanted to learn how to code EA with GlobalVariables. I cannot code, I am just a general user and I just want to know correct way to use EA (with or without GlobalVariables).
I asked this question as I experienced that some EAs were locked when I removed the EA with position opened and I had to raised a new account and install a new MT4 Terminal. I raised the same question in other forums but nobody can give a full answer.
I think it may be better to move previous post to General Discussion Section or Set Up Question Sectiom of this forum.
Thanks in advance.

I don't know the answer.

As to small threads so I am always menging small stand-alone threads with the other big threads. because forum is big and sometimes members are trying to open separated threads for just one question and in the end of the day we are having 10 or 20 separated threads with 1 or 2 posts. So, i am always merging ...

This programming section is for the people whio probable know the answer for your question.

Yes Sir !
You know what is the best to this Forum and you are at the position to maintain it.
Sorry for giving you extra work load.
Regards.

I think " if ( alertTag!=Time[0]) " means if not same send mail and alert

but I do not understand " alertTag = Time[0]; " meaning at all .

alet and send mail is finish.why need this code????



if ( (fasterMAnow > slowerMAnow) && (fasterMAprevious <
slowerMAprevious) && (fasterMAafter > slowerMAafter)) {
CrossUp[i] = Low[i] - Range*0.5;
if ( alertTag!=Time[0]) ←
{
PlaySound(SoundWAV);// buy wav
Alert(Symbol()," M",Period()," MA cross BUY");
SendMail(Period()+" hit MA long ",Bid +"long");
}
alertTag = Time[0]; ← what mean???

}

It is needed to run the sound/alert/mail routine maximun only once per bar

Ok, I've done my due diligence to try and solve this problem to no avail. I have downloaded and used many mq4 advisors/indicators.. I know the process for that. However, EX4 files are something different. I know ex4 files are suppose to be like mq4 files but with the code hidden. Anyway, whenever I save these files into metrader4 experts/indicators ...close program and reopen they are not in the folder. What am I doing wrong. It seems Metrader only recognizes mq4 files. Any help is appreciated. I cant seem to find any info. it seems othere people are having the same problem but no one has supplied an answer.
Thanks

ex4 is compiled file from mql4 ...maybe your MT4 not yet updated or there's wrong syntax code in your mql4 ...

Forex Indicators Collection

Friends, can anyone please explain me in simple english that what is SHIFT parameter in iMA method?

double iMA(string symbol, int timeframe, int period, int ma_shift, int ma_method, int applied_price, int shift)

according to MT4 help, its "Index of the value taken from the indicator buffer (shift relative to the current bar the given amount of periods ago)." - what is indicator buffer???

please help.

cheers

0 means current value of ma
1 means value of ma of last candle
2 means value of ma of last but one candle
etc....

In an EA, I have SL=50.

How change it to have SL=50 or crossing of 2 MAs ?

Thanks for help.
