Hi ABers,

I'm trying to do something really simple but am stumped by AFL's
behavior, and the docs don't clear it up.  If I want to do a
comparison of the current price with a price x bars ago, how do I pull
out a single value for the if-statement to work on?  i.e. someone
please correct,

price_today = close[0] ;
price_yesterday = close[-1] ;

if (price_today > price_yesterday)   etc. etc.


...a negative index number is not accepted, and the tutorial
"Understanding how AFL works" implies the latest price is the highest
array index number??  How does that work, without knowing the array
size beforehand?  Is there another doc I'm missing?  Thanks,

kw
