[amibroker] Re: What's AFL for 'selling on close 3 days later'

["onlyobsession2k3" <jmpatton@xxxxxxxxxxxxx>]

I'm new to AFL so forgive if these questions seem simple:

1) Regarding the post below, the AFL Function reference says that in
the Ref function, a positive number refers to the future, so wouldn't
"three days later" be Ref(Close,3) and not -3? Is the help
documentation incorrect?

2) How would I write a simple formula like "Buy on Close, Sell on
Open"? I tried the following, but it seems to buy & sell on the same day?
Buy=Close
Sell=Ref(Open,-1)
