I've been reading for three days now. :=( It's easier in php, but I can't understand it here.

I agree with the moderator, it's better to mark orders/positions than to compare open prices. In addition to magic number, you can use check for comments. You can write the opening price in the comment (e.g. "EURUSD 1,251").

In addition to the magic number, comment checking can also be used. The opening price can be written in the commentary (e.g. "EURUSD, 1.251").

This is dangerous: the server can change/add comments to orders under certain conditions, so in this case you risk getting caught unawares. Even in the tester, when something like "[sl]" is attached to the comment.

Help a self-taught programmer.

Built a trend line with standard tools.

Trend line by angle. I use the first coordinate and angle. The ObjectSet() function is used to set the line angle (OBJPROP_ANGLE property)

Need to determine if the price is above or below the trend line at 0 or 1 bar.

The first coordinate of the trend line is known, but the second coordinate is unresolved. It is mandatory for the calculation formula.

It is present on the chart when it is selected with the mouse. Is there any way to determine it?

We have some other ways of determining it.

Preferably share the code if you can.

Or approach it in some other way.

Since you have already built it, how about ObjectGetValueByShift()?

Offset relative to the current bar deep into history. Returns 0.

There is no second coordinate.

That's not it or I don't get it.

Hello!

Can you advise a newcomer on whether a include file needs to be compiled?

What is the difference between a include file and a library? Where is it better to store functions: in a include file or in a library and why?

Eh... I don't need coordinates, we pass the name of line object and bar number (0 or 1, as you wrote) into the function, the output is the line value on this bar. We compare it to the price... Or I don't understand the problem?

no

What is the difference between a include file and a library?

The first one does not need to be compiled, because it is included into the program code itself, the second one does, because its functions are included from the ex4-file

Where is it better to store functions: in a include file or in a library and why?

For your own use, it would probably be better in mqh; if you need to distribute the library and don't want to open the source code, then ex4. The function call from ex4 is quite slow, but if the performance is not critical, then in principle, whatever

s="doun";
if (ObjectFind(s)==0) {ObjectDelete(s);}
ObjectCreate(s,OBJ_TRENDBYANGLE,0,Time[W1],High[W1]);
ObjectSet(s,OBJPROP_ANGLE,310);

double price=ObjectGetValueByShift("doun", 1);

Comment(price);

returns 0.

line is present.

Somebody write a normal tester, multi-currency and with floating spreads))))

ps and also with real ticks, blackjack and whores

Thanks everyone for the tips and help)))) If someone will write a tester and share, I think there will be a lot of grateful people.... I do not have enough knowledge for that yet.... learn, learn and learn...))))
