Hello. Can youwrite an EA for this indicator? The indicator can draw until the close of the candle, as the candle closed arrow is not missing. Can we make the order open after fixing the arrow indicator? Ie on the next candle after the arrow. Fixed lot and the ability to transfer to Breakeven trades after a specified number of points. I would be very grateful!demonoid123000@mail.ru

Nah, it's not a question... I wanted to answer the person who asked how to get an Ask. Without avatars, it's hard to see who's asking and who's answering, and who's answering too. Sorry.
 
Sergey Gritsay:

I think this would be more interesting

version 1

version 2

More interesting, but not clear, for beginners - that's me...

This is a custom function, here's an example of how to use it

I understand that it's a custom function.

In the second example it is not clear where the Day() function sends to

What do you mean where? This is the function from the documentation

Day

It returns the current day of the month, i.e. the day of the month of the last known server time.

intDay();

Returned value

The current day of the month.

Note

During testing, the last known server time is simulated.

Example:

if(Day()<5)return(0);

Wow I'm dark - thanks for the enlightenment - didn't know.

Time to teach the forum to highlight functions in full!

 
Guys, help me write a simple Expert Advisor! I would be very grateful!!!
