Yes they probably could be used ... but I have no knowledge of how
useful or time saving this would be ... I would think that unless the
individual indicators themselves are extremely time consuming that it
might not be worth it and how one tells where the breakeven point is
before the fact I have no idea. Therefore I would think from a
development perspective one would have to make a choice to do it this
way or that way all the time depending on what the benchmarks showed.
