Graham,
You gave a very good suggestion. I did not think about function cross
().
However, it is still not working. I have checked to make sure the
intraday data around that time period are there.
And another issue I have is that I can only scan it once. If I try it
again, there is no output to the Alert Output window.
I have to restart the whole amibroker.
