#42 add AND, IF and SUM() functions to scanner

[Samwise]

maybe I am just not seeing it, but I am missing functions like AND, IF, or SUM().

In older versions of qtstalker I could combine several indicators/triggers by summing up the results of a bunch of logical comparisons.

See here more detail on what I mean:
