I don't think you should post in this thread any more - it's not here to teach you how to read/write or how to speak. It's about helping newcomers. And you're not a beginner, you're a baby :)

ZS. I already gave you a link on where to start. And it doesn't matter that it's on fives - it's the same language. The API is different.

Well.... before you get banned...... , according to the rules of freelancing, babies are not forbidden to pee. So I wrote - what can you do with a baby - he does not know what he's doing. And there are a lot of branches here, the tree is big, growing, I wish the tree good health.

IMHO ( I'll pretend too ) there are a lot of links and they do not fit in your head. And here people ( not references ) gave a little help - they did good and did not send us to ...... or to Siberia into exile.

Brothers in exile! Help me figure out how to solve the second task! There is one line Coment ( str ) and on the monitor "Hello" should light up.

this can be done via the terminal's global variables. Provided you have the source code of the indicator and can edit it.

It means that indicator will perform calculations by getting parameter not through extern but from calling GlobalVariableGet(). And accordingly the Expert Advisor will change this variable through GlobalVariableSet

I would like to make a couple of improvements to MT5:

1. Reduce the number of digits on the chart from 5 to 4, the broker does not want to do this.

2. For some reason, when I set the bid line colour, the price background becomes the same colour and merges with the background.

If I set the colour black, I will get a solid line across the whole screen which is very distracting.

As far as I understand, the best way to do it is to output the price value as a text marker. How can I make it move when the price changes?

It's possible that my question has already had a solution for a long time, but I haven't found anything by searching.

As long as they haven't created a "Any Questions for Babies" thread, I'll pretend to be a newbie and ask questions here. I meant the second assignment. I copied it exactly. There's only a couple of words I put in the template, but there's a lot of error

String str ="Hi ";

Comment (str );
