I have been using indiors for years, all sort. I had ups and downs but ultimately and fortunately I stopped using them two weeks ago and never traded and I'm doing now, that means that you need to develop a system that has just price, past and present, as input parameter and no other calculation on it, that's exactly what indiors are.

So indiors are just smoke and that for me is a fact, not an opinion. I trade now with them and won't ever come back to them because even if my system or trading is not yet constant or viable in the long run, I understand now that I really don't need them to improve my trading or system and this really is liberating and game altering.
