Hello, do you know if mql4 will be supported in the future, when it seems that mt4 is no longer available?
It has never been sold, it has always been free.
 
Alexey Viktorov:
That was never the case, it has always been free.

do brokers use mt for free at the metaquotes?

 

Dear friends, help me out here. I have tried to write my own indicator based on ZigZag, or to be more precise, to output its averages. I've got awrong drawing and in the comment the average is not standing still and grows withevery tick, while the array is clearly shown. Please advise me the correct code. I'm attaching mine:


that's how he draws


Here's the code:

hello, is there any info on whether mql4 will be supported in the future, if it seems like mt4 sales have stopped?

 
Alexey Viktorov:

Read between the lines, even if it is just one line ))

I have to practice... I'll try to start training tomorrow.

MT4 development is stopped, MQL4 support is very limited (or stopped too), that's all the info from the forum.

It's time for MT5.

Time for MT5.

Updated to 1127 yesterday - about support. About development - not anymore.

 
Sergey Basov:

The development of MT4 is stopped, support for MQL4 is very limited (or also stopped), that's all the info from the forum.

I am thinking of going deeper into mql4 or am I just wasting my time?

I have some skills with mql4 , i think i will go deeper, but i don't know if it will be a waste of time?

 
Вадим Мотеюнас:

My opinion: If I have "some", there will not be much "loss" in switching to mql5. The languages are pretty much the same with only minor differences/wording. The difference is in the trading API and functions to work with it.

So, start writing in mql5 and with its study the knowledge on mql4 will be increased.
