[amibroker] Re: AFL code question

Hello Ara and Barry,

Thank you for your contribution but, please take into account my vast
two week experience in using AmiBroker and explain where do I
substitute my entry condition? In Barry's code "ai" array is not
initialized and gives an error. I assume that, this is not a complete
code. Can you please give me a simple working example which I can use
to understand the logic of the AFL code?

Is there an example somewhere in the AFL library which shows using
valuwhen to identify specific bar break out?

Regards
Richard
