Hello,
x = ... condition for signal 1
y = .... condition for signal 2
dn = DateNum();
barx1 = ValueWhen( x, dn );
barx2 = ValueWhen( y, dn );
x_y_are_on_same_bar = ( barx1 == barx2 ); // note the result will also be array
(vector)
The other approach (if you operate in loop and processing bar by bar
and when you know the bar number (scalar)) you can use the following
dn = DateNum();
bar1 = ... some calculation that gives you scalar bar number
bar2 = ... some calculation that gives you scalar bar number
if( dn[ bar1 ] == dn[ bar2 )
{
// the DAY is the same for both bars
}

Ok. Thank you Tomek for help. I'll better read something more about AFL.
Maybe you can tell me one more thing:
I have two 5m bars : How can I compare them ( i mean bool information if it
is the same day or not) .
Thanks for help

This is absolutely must read for everyone, and especially for people who
think
"I know C++ and the syntax looks the same for me".
AFL is array (vector processing) language, it is much higher level than C++
and you need
to learn to think with vectors in mind.
Your question is way too general to give you answer. You need to specify
exactly what
you want.
There are lots of samples here:

Ok, I used loops and it worked ok ( habbits from C++)
But I'm sure that you are right ;)
In this case, how can I control my system ? I mean, for example i want
use different signals depends on current position (long,short or size of
position)?
Maybe someone can give me some example.
I will be grateful.
Best regards

Advice for the novice: *DO NOT* use loops!
They are only needed in very few cases
and NEVER if you are beginner.
Correct formula would be WITHOUT any for loop and WITHOUT
subscripts.
CoverPrice = TimeFrameExpand( Wsk,inDaily);
