I assume you will spend more than a second thinking of a new trading
strategy and describing it with sufficient precision for your program
to be able to test it. If it takes several minutes for you to do your
part, is it so important for the program to do its part in under a
second?

Write your program. Use it. If it's too slow, you can always change its
scanning method later.
