A couple of things to remember
barindex() starts from 0 at the first bar (oldest) of your database
and counts up from there to the end (most recent) of the database.
Bacount is the total number of bars in the database, but Barcount-1 is
the last barindex() value
If you are using certain bar functions like loops in a chart then you
often need to voercome the amibroker method of faster chart drawing,
where it uses the least number of bars to calculate what shows on the
screen. Using Setbarsrequired function allows this behaviour to be
overridden and all the bars in the array can be used.
If you have a function as part of a buy or sell condition that dows
not get its first value until the number of bars is met (periods in
the function eg MA(C,10) is 10 bars to get first MA value) the you
could be required to tart the loop after this minimum number of bars
for( i=10;i<barcount;i++)
