Ah ha! This is the proper way to buy at the Open price (O). This is what
you want to do to simulate putting in an order to buy before the market
opens. I don't believe I have seen this described anywhere in the docs, but
I may have missed it since I hadnt been looking for it.
Note that the Buy expression is checking the previous bar's condition (i.e.
Ref(condition, -1)). You should not buy at the open price based on any
other information for that time (i.e. H, L, C, V), because that would require
time travel, but AmiBroker lets you do it without warning.
Most code examples assume Buy at the Close based on any information during
that time bar.
Thanks emp!
