Hello
Also Me I have a Question here that is about the " XShift " I would like to project into future from last Bar. Below is the code . how can we do that?
@ Milosz I start this code few weeks ago and I was interesting about the Xshift and not for the main code but yes right SelectedValue(BI)
@ Alan try this. diff = ( stop - start); "\ndiff Bi to Bi "+ WriteVal(diff);
Apparently we are going to answer slow-slow all the questions that Posted by: abdullahalrafee1, with this conversation, and I really like that.

First of all… yes FX he is right. But all of us we know that about SetBarsRequired(). I think?
And I really like him answer my question.
For example, if my selected area from point A to point B is 1000 bars before the last bar. And now I like to Zoom maybe to 150 visible bars and also to press key "END" to see the future bars. How can I do this without not using SetBarsRequired()?
Thanks in advance

So if I wanted to use this code to perform some function like find the difference between the two prices I would use for variables
"bi == start" as one variable and "bi == stop" as the second variable and subtract the two like this: diff = bi == stop - bi == start. Is this correct?

That code has some flaws/overkills
overkill:
using SetBarsRequired( sbrall, sbrall ); just makes code slow because of using all bars
If you want to know overall bi in Information window then use status( "quickaflfirstdatabar" )
Like so,
qfdb = status( "quickaflfirstdatabar" );
printf( "startBi: %g\nendBi: %g", (qfdb + start), (qfdb + stop) );
Then you don't require SetBarsRequired(sbrall)
coding flaws:
using LastValue( SelectedValue( bi ) )
just use SelectedValue( bi )
since both LastValue and SelectedValue are used on arrays but not on scalars.
Using both together makes not sense.
some other note
IIf(bi==start,1,0) can be repalced by just using bi == start (same for stop)
StaticVarSet( "StartbarBi"+getchartid(), SelectedValue(BI)) is never called by any StatiVarGet.
So it is code cadaver, so to say. So it can be removed. It just confuses.
