HELP me --> Metatrader Bag (Angle Line)--OBJ_TRENDBYANGLE

New comment
 
Hello my frinds .
I Have big problem .


Description for Up picture :

When the line is made, it does not give me its Angle twice.
One in that OnInt ().
One in that OnTick ().
The third time a new price tick appears, it returns the correct value.
What is wrong ?
Why not turn the angle the first time?
Is there a problem with MetaTrader?
Is there a problem with the code?
In any case, thank you for your help.
A world, thank you dear friend.

If there is a real problem with my code, thank you for Tell me what code to use to fix my problem.

Hello.

Thank you for watching my questions.

I'm very sorry, but instead of being upset, guide me.

You return from OnTick. Then the objects are drawn. Don't read them prior.

 

Objects are drawn asynchronously.

https://www.mql5.com/en/docs/objects/objectcreate

Return Value

The function returns true if the command has been successfully added to the queue of the specified chart, or false otherwise. If an object has already been created, an attempt is made to change its coordinates.


You have to make sure the object exists on the chart before attempting to read its properties.

Hello Dear William Roeder .
Thank You . 
Can you explain more?
Thank You very much .
I have been working on the method for a long time to solve the problem.

Hello Dear  Alexandre Borela Thank you very much . 


I used the ObjectFind function, but it returns the output of function 0, which means the object is created. But it returns the angle to 0 again.

I had not read the reference. However, with your explanation, new knowledge was added to me. But my problem is still unresolved.

I did not solve my problem using the ObjectFind function because ObjectFind returns a value of 0, which means that the object is built.

But it returns the angle to zero again.

my dear friend .

If you do not have the power to help me and you can not help me, please do not make fun of me and shut your mouth and just watch.

I am not your friend in any way.

Your issue has been discussed numerous time on this forum, so my posts. You are not only unable to use the search engine but also to stay civil, using a lot of fake "dear".

You don't deserve any help.

If you could help, you would help me instead of making fun of me.

You're not God who determines deserve.
