Quicker to figure out and understand
write down the prices, how to take them afterwards, when what?
to insert in this loop instead of rHello, I have made a function which should increase the stop loss after the last order has closed in minus.
Increases it by the set step, until it reaches the maximum. As a result, it always sets the original value of stop loss.
What is wrong? Thank you!

What am I writing it wrong?
It should go like this http://prntscr.com/lu1kb9
Tried to insert the data under the current template
But it's still not the same. help meGood afternoon.
I am mastering emq-el by Sergei Kovalev's tutorial.
I downloaded the Expert Advisor from there, compiled it, it even seems to work, but when compiling it displays some comments, not errors, but warnings.
What should I change to make it compile without any errors? Thank you in advance.
Where can I find the error codes? Where is this documentation?
In the menu of this website - look up![](https://c.mql5.com/3/257/vzdoh2__1.gif)

Artem, there is documentation on mql5, and the questions are in the mql4 section
Sergey Branin:

Here is mql4 documentation. You may also press F1 in MetaEditor
Artyom, is the mql5 documentation there? and the questions are in the mql4 section
There is a documentation on mql4. And it is better to press F1 while in the MetaEditor
Ahh... Well all the same - it's not so complicated either - it's faster to put your finger on F1 and find everything you need than to wait 24 hours for an answer on the forum. I don't understand ...![](https://c.mql5.com/3/257/neznaet__1.gif)
I do not know how to do it, may any programmer write a simple code block for an example. c/o Denis
