It works because you are comparing the changing value of BarIndex() to
the fixed (numeric) value of LastValue().
The result is an array full of 0's with a single 1 marking the actual
last day of the selected/current symbol.
It's the same as saying Buy = cond1 AND C > 10;
Here you are comparing the Close to a numeric value of 10 since you only
want to Buy stocks whose price > $10.

Subject: [amibroker] A question for this simple code with BarIndex()
in BarIndex() function help, has the following example code
ThisIsLastBar = BarIndex() == LastValue( BarIndex() );
my question:
1. BarIndex() return array but LastValue return a number, when array
type can compare with number type?
I tried it, it even works :-)
